The two Coombs tests are the direct Coombs test (DCT, also known as direct antiglobulin test or DAT), and the indirect Coombs test (also known as indirect antiglobulin test or IAT). The direct Coombs test is used to test for autoimmune hemolytic anemia; i.e., a condition of a low count of red blood cells (aka RBCs) caused by immune system lysis or breaking of RBC membranes causing RBC destruction. In certain diseases or conditions, an individual's blood may contain IgG antibodies that can specifically bind to antigens on the RBC surface membrane, and their circulating RBCs can become coated with IgG alloantibodies and/or IgG autoantibodies. Complement proteins may subsequently bind to the bound antibodies and cause RBC destruction.[1] The direct Coombs test is used to detect these antibodies or complement proteins that are bound to the surface of red blood cells; a blood sample is taken and the RBCs are washed (removing the patient's own plasma) and then incubated with anti-human globulin (also known as "Coombs reagent"). If this produces agglutination of RBCs, the direct Coombs test is positive, a visual indication that antibodies (and/or complement proteins) are bound to the surface of red blood cells. The indirect Coombs test is used in prenatal testing of pregnant women and in testing blood prior to a blood transfusion. It detects antibodies against RBCs that are present unbound in the patient's serum. In this case, serum is extracted from the blood sample taken from the patient. Then, the serum is incubated with RBCs of known antigenicity; that is, RBCs with known reference values from other patient blood samples. If agglutination occurs, the indirect Coombs test is positive.[2] The two Coombs tests are based on the fact that anti-human antibodies, which are produced by immunizing non-human species with human serum, will bind to human antibodies, commonly IgG or IgM. Animal anti-human antibodies will also bind to human antibodies that may be fixed onto antigens on the surface of red blood cells (also referred to as RBCs), and in the appropriate test tube conditions this can lead to agglutination of RBCs. The phenomenon of agglutination of RBCs is important here, because the resulting clumping of RBCs can be visualised; when clumping is seen the test is positive and when clumping is not seen the test is negative. Common clinical uses of the Coombs test include the preparation of blood for transfusion in cross-matching, screening for atypical antibodies in the blood plasma of pregnant women as part of antenatal care, and detection of antibodies for the diagnosis of immune-mediated haemolytic anemias. Examples of alloimmune hemolysis[edit] Hemolytic disease of the newborn (also known as HDN or erythroblastosis fetalis) Rh D hemolytic disease of the newborn (also known as Rh disease) ABO hemolytic disease of the newborn (the indirect Coombs test may only be weakly positive) Anti-Kell hemolytic disease of the newborn Rh c hemolytic disease of the newborn Rh E hemolytic disease of the newborn wikipidea https://en.wikipedia.org/wiki/Coombs_test Watch Again https://youtu.be/4MJA8Wzp2XM Subscribe https://www.youtube.com/channel/UCOmrniWfKi-uCD6Oh6fqhgw -~-~~-~~~-~~-~- CHECK OUT NEWEST VIDEO: "Nucleic acids - DNA and RNA structure " https://www.youtube.com/watch?v=0lZRAShqft0 -~-~~-~~~-~~-~-

How Widal Test is done for Typhoid Fever?  | 1mg
 
01:40
Widal test is a blood test which detects Enteric fever (Typhoid fever and Paratyphoid fever)The Widal test measures the titres of antibody against the bacteria which cause Enteric fever. What is Typhoid Fever? Typhoid fever is a type of Enteric fever and results due to infection of the intestine by bacteria. The two types of Enteric fever are: Typhoid fever - It is caused by a bacteria Salmonella enterica serotype Typhi (S. Typhi). Paratyphoid fever - It is caused by bacteria Salmonella enterica serotypes Paratyphi A (S.Paratyphi A), Paratyphi B (S. Paratyphi B) or Paratyphi C (S. Paratyphi C). How Does the Fever Spread? The Typhoid fever spreads through the ingestion of contaminated food and water. What are the Symptoms of the Fever The following are the symptoms of Typhoid fever: High fever Stomach pain Headache Tiredness Weight Loss Diarrhea or Constipation What should be done if you have the symptoms? In case you have the above symptoms, consult a doctor. How is the basis of the Widal Test? Widal test is an agglutination test that detects antibodies (agglutinins) in a blood sample against two antigens (O & H) of bacteria, Salmonella enterica. Agglutination refers to the visible clumping of particles when a particulate antigen combines with its antibody in the presence of optimum conditions for antigen-antibody reaction. Widal test should only be performed after the first week, as an antibody against “O” and “H” antigens of Salmonella start appearing in the serum at the end of the first week of fever. It is preferable to test two blood samples at an interval of 7 to 10 days to demonstrate rising antibody titres. How is the Widal Test done? A blood sample is taken from your vein to do the WIdal Test wherein it can be done by the following two methods Slide agglutination method Tube agglutination method When the Widal test is performed in a test tube, it is called Tube agglutination and when it is carried out on a slide, it is called Slide agglutination. Widal test by Tube agglutination is recommended over Slide agglutination method. The antigens used in the test are “H” and “O” antigens of Salmonella Typhi and “H” antigen of S. Paratyphi. What does the test mean? Active typhoid infection is confirmed if the test shows the following Titre of 1:80 or more for O agglutination 1:160 or more for H agglutination A rise in titres (4-fold or more) in the two blood samples taken 10 days apart confirms the diagnosis. When can the test be false? In the early stages of the infection, the Widal test may give a false negative result. False-positive result may be seen due to past infections or vaccination Do not take medicine without consulting your physician. #widal_test #typhoid fever #typhoid_treatment Please visit https://www.1mg.com/labs/test/widal-test-1970 for more information.

Procedure of Widal  Test
 
05:08
Widal test In 1896 and named after its inventor, Georges-Fernand Widal, is a presumptive serological test for enteric fever or undulant fever whereby bacteria causing typhoid and malaria fever are mixed with a serum containing specific antibodies obtained from an infected individual. In cases of Salmonella infection, it is a demonstration of the presence of O-soma false-positive result. Test results need to be interpreted carefully to account for any history of c fever, typhoid vaccination, and the general level of antibodies in the populations in endemic areas of the world. Typhidot is the other test used to ascertain the diagnosis of typhoid fever. As with all serological tests, the rise in antibody levels needed to perform the diagnosis takes 7–14 days, which limits its applicability in early diagnosis. Other means of diagnosing Salmonella typhi (and paratyphi) include cultures of blood, urine and faeces. These organisms produce H2S from thiosulfate and can be identified easily on differential media such as bismuth sulfite agar. 2-mercaptoethanol is often added to the Widal test. This agent more easily denatures the IgM class of antibodies, so if a decrease in the titer is seen after using this agent, it means that the contribution of IgM has been removed leaving the IgG component. This differentiation of antibody classes is important as it allows for the distinction of a recent (IgM) from an old infection (IgG). The Widal test is positive if TO antigen titer is more than 1:160 in an active infection, or if TH antigen titer is more than 1:160 in past infection or in immunized persons. A single Widal test is of little clinical relevance due to the high number of cross-reacting infections, including malaria. If no other tests (either bacteriologic culture or more specific serology) are available, a fourfold increase in the titer (e.g., from 1:40 to 1:640) in the course of the infection, or a conversion from an IgM reaction to an IgG reaction of at least the same titer, would be consistent with a typhoid infection. A new serological test called the Tubex test is neither superior nor better performing than the Widal test. Therefore, Tubex test is not recommended for diagnosis of typhoid fever.[1] join with us: https://www.facebook.com/mtjmbd email us at: [email protected] watch our other video tutorials: Technique/ Procedure of Widal Test https://www.youtube.com/watch?v=pF28SaGEPjA Operating details of Short Wave Diathamy (SWD) https://www.youtube.com/watch?v=kP3wt49Sig4&t=2s Blood Group Procedure https://www.youtube.com/watch?v=jv2HzC0LFzE Calibration procedure in Automatic Biochemistry analyzer(Dimension) https://www.youtube.com/watch?v=PIjVRlDtIw0&t=2s How can you setup new dr list into CBC Cell Counter https://www.youtube.com/watch?v=bGLBNkPkRx8 How can make a CBC report by using Cell Counter machine https://www.youtube.com/watch?v=N_nni3KKoGQ Procedure of serum Bilirubin (total).new tutorial.using biotrade reagent. https://www.youtube.com/watch?v=GUj_CVWOsLA Procedure of urine culture https://www.youtube.com/watch?v=9I6_zsAvO1Y&t=9s Procedure of Creatinine Test https://www.youtube.com/watch?v=9xCP7pCY0Zw How can you performed ESR in Caretium auto machine https://www.youtube.com/watch?v=_g7Co-pAdv8&t=73s A to Z about the PHYSIOTHERAPY with practical https://www.youtube.com/watch?v=7bWXHihztII&t=4s

Welcome to Harib Diagnostic lab we are providing Diagnostic Facilities Hematology Micro Bilogy Bio Chemistry Elisa Typhoid test fever temperature# Blood test , Harib Diagnostic Lab https://youtu.be/3j4pogYdSqY Causes S. typhi is spread through contaminated food, drink, or water. If you eat or drink something that is contaminated with the bacteria, the bacteria enter your body. They travel into your intestines, and then into your blood. The bacteria travel through the blood to your Lymph nodes, Gallbladder, Liver, spleen, and other parts of the body. Some persons become carriers of S. typhi and continue to release the bacteria in their stools for years, spreading the Disease. Typhoid fever is common in developing countries. Fewer than 400 cases are reported in the U.S. each year. Most cases in the U.S are brought in from other countries where typhoid fever is common. Symptoms Early symptoms include fever, general ill-feeling, and abdominal pain. High fever (103°F, or 39.5°C) or higher and severe diarrhea occur as the disease gets worse. Some people with typhoid fever develop a rash called "rose spots," which are small red spots on the abdomen and chest. Other symptoms that occur include: Abdominal tenderness Agitation Bloody stools Chills Difficulty paying attention (attention deficit) Delirium Fluctuating mood Slow, sluggish, lethargic feeling Weakness Exams and Tests A complete blood count (CBC) will show a high number of white blood cells. A blood culture during the first week of the fever can show S. typhi bacteria. ELISA urine test to look for the bacteria that cause Typhoid fever Fluorescent antibody study to look for substances that are specific to Typhoid bacteria Platelet count (platelet count may be low). Treatment Fluids and electrolytes may be given by IV (into a vein). Or you may be asked to drink uncontaminated water with electrolyte packets. Antibiotics are given to kill the bacteria. There are increasing rates of antibiotic resistance throughout the world, so your health care provider will check current recommendations before choosing an antibiotic. facebook https://www.facebook.com/profile.php?id=100015591840955 Google plus https://plus.google.com/b/101683933727326950082/collection/8uY-PE twitter https://twitter.com/HDLAB4 Please Subscribe my channel Like And Share Thanks For Watching

Salmonella typhi IgG/IgM Test

***Caution: This product is not 510(k) cleared by US FDA and thus is not for sale in the United States.*** INTENDED USE QuickProfile™ S. Typhi IgG/IgM Duo Test is an in vitro qualitative immunochromatographic assay for the rapid detection of anti-S.Typhi antibodies in human whole blood/plasma/serum specimen. The test results are intended to help in the diagnosis of S. Typhi infection. INTRODUCTION Typhoid fever is a life threatening illness caused by the bacterium Salmonella typhi, and was observed by Eberth (1880) in the mesenteric nodes and spleen of fatal cases of typhoid fever. It is common in developing countries where it affects about 12.5 million persons annually. The infection is acquired typically by ingestion. On reaching the gut, the bacilli attach themselves to the epithelial cells of the intestinal villi and penetrate to the lamina and submucosa. They are then phagocytosed there by polymorphs and macrophages. The ability to resist intracellular killing and to multiply within these cells is a measure of their virulence. They enter the mesenteric lymph nodes, where they multiply and, via the thoracic duct, enter the blood stream. A transient bacteremia follows, during which the bacilli are seeded in the liver, gall bladder, spleen, bone marrow, lymph nodes and kidneys, where further multiplication takes place. Towards the end of the incubation period, there occurs a massive bacteremia from these sites, heralding the onset of the clinical symptoms. The symptoms of the illness include high fever, headache, abdominal pain, diarrhea or constipation. A quick and accurate diagnosis of typhoid fever at an early stage is not only important for etiological diagnosis, but also to identify and treat the potential carriers and prevent acute disease outbreaks. QuickProfile ™ S. Typhi Antibody Duo Test takes only 10-20 minutes and requires only a small quantity of sample to perform. It is a easy and specific method for detecting S. typhi infection.

Can positive Widal Test indicate Typhoid without fever? - Dr. Anantharaman Ramakrishnan
 
01:15
The WIDAL test is an outdated test. So it does not have any value in the Indian scenario, whereas most Indians have been exposed to vaccinations for typhoid for typhoid fever in the childhood. So in such cases, WIDAL test is of not much use. Any fever can cause elevation in the WIDAL titres. This is called as an anamnestic reaction. So the generalized increased in antibodies in a person who has fever. In a person who does not have fever, and it is positive no matter whatsoever. So the only way to diagnose. Salmonella infection is a blood culture, stool culture or a urine culture. So that is the way to diagnose salmonella.

(excreta means toilet) Problem is diagnosis of this Fever.Unlike malaria,chikungunia,dengue etc fever their diagnosis is done by clinically with immediate lab report but diagnosis of typhoid takes time.Widal test positive after 1st week. Treatment consist of antibiotic therapy for 2 week.Cephalosporin & fluoroquinolone groupnof medicines used. In some patient may may reoccur within few days of treatment then antibiotics for 4 week suggested. In any disease prevention is easy then treatment so take care about it.

By virtue of its long history and of its simplicity, it has been one of the most widely employed tests for rickettsia on a global scale, despite being superseded in many settings by more sensitive and specific diagnostic tests. The basis of the test is the presence of antigenic cross-reactivity between Rickettsia spp. and certain serotypes of non-motile Proteus spp., a phenomenon first published by Edmund Weil and Arthur Felix in 1916.[1] The serum of patients diagnosed with epidemic typhus was found to agglutinate in the presence of bacteria now known as Proteus vulgaris. Ensuing work elucidated that it was in fact the somatic (O) antigen that cross-reacted with anti-rickettsial antibodies, and furthermore, that different Proteus O antigens would cross-react with different species of Rickettsia. Typhus group rickettsiae (Rickettsia prowazekii, R. typhi) react with P. vulgaris OX19, and scrub typhus (Orientia tsutsugamushi) reacts with P. mirabilis OXK. The spotted fever group rickettsiae (R. rickettsii, R. africae, R. japonica, etc.) react with P. vulgaris OX2 and OX19, to varying degrees, depending on the species.[2] The Weil–Felix test suffers from poor sensitivity and specificity, with a recent study showing an overall sensitivity as low as 33% and specificity of 46%.[3] Other studies have had similar findings.[4] As a result, it has largely been supplanted by other methods of serology, including indirect immunofluorescence antibody (IFA) testing, which is the gold standard. However, in resource-limited settings, it still remains an important tool in the diagnosis and identification of public health concerns, such as outbreaks of epidemic typhus. Slide method[edit] On a solid surface (glass slide, tile, card), a small amount (50–100 μL) of the patient’s serum is placed. A single drop of the desired antigen is added, and the resulting suspension is mixed and then rotated for one minute. Visible agglutination is indicative of a positive result, and corresponds roughly to a titer of 1:20. Positive results can be further titrated using the tube method, which is more labour-intensive. Tube method[edit] Using 0.25% phenol saline as a diluent, a series of tubes containing twofold dilutions of patient serum are made with a final volume of 1 mL. A drop of antigen suspension is added to each tube, and the mixture is incubated at 50–55 °C for 4–6 hours. A positive tube would show visible flocculation or granulation, which is accentuated when the tube is gently agitated. The titer corresponds to the most dilute tube in the series that still shows positivity. Generally, a titer of ≥1:320 is considered diagnostic.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ An antibody titer is a measurement of how much antibody an organism has produced that recognizes a particular epitope, expressed as the inverse of the greatest dilution (in a serial dilution) that still gives a positive result. ELISA is a common means of determining antibody titers. For example, the indirect Coombs test detects the presence of anti-Rh antibodies in a pregnant woman's blood serum. A patient might be reported to have an "indirect Coombs titer" of 16. This means that the patient's serum gives a positive indirect Coombs test at any dilution down to 1/16 (1 part serum to 15 parts diluent). At greater dilutions the indirect Coombs test is negative. If a few weeks later the same patient had an indirect Coombs titer of 32 (1/32 dilution which is 1 part serum to 31 parts diluent), this would mean that she was making more anti-Rh antibody, since it took a greater dilution to abolish the positive test. Many traditional serological tests such as hemagglutination or complement fixation employ this principle. Such tests can typically be read visually, which makes them fast and cost-effective in a "low-tech" environment. The interpretation of serological titers is guided by reference values that are specific to the antigen or antibody in question; a titer of 1:32 may be below the cut-off for one test but above for another.

What does SEROLOGY mean? SEROLOGY meaning, definition & explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Serology is the scientific study of serum and other bodily fluids. In practice, the term usually refers to the diagnostic identification of antibodies in the serum. Such antibodies are typically formed in response to an infection (against a given microorganism), against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in instances of autoimmune disease). Serological tests may be performed for diagnostic purposes when an infection is suspected, in rheumatic illnesses, and in many other situations, such as checking an individual's blood type. Serology blood tests help to diagnose patients with certain immune deficiencies associated with the lack of antibodies, such as X-linked agammaglobulinemia. In such cases, tests for antibodies will be consistently negative. There are several serology techniques that can be used depending on the antibodies being studied. These include: ELISA, agglutination, precipitation, complement-fixation, and fluorescent antibodies. Some serological tests are not limited to blood serum, but can also be performed on other bodily fluids such as semen and saliva, which have (roughly) similar properties to serum. Serological tests may also be used in forensic serology, specifically for a piece of evidence (e.g., linking a rapist to a semen sample).

In this medical video - HIV negative person undergoes an instant HIV test. Also with an HIV positive person. This video is all about the process of doing HIV rapid antibody test on HIV infected (positive) person and HIV negative person and reading the result Principle HIV antigens are immobilized on a porous immunofiltration membrane. Sample and reagents pass through the membrane and are absorbed into the underlying absorbent. As the patient’s sample passes through the membrane, HIV antibodies, if present, bind to the immobilized antigens. Conjugate binds to the Fc portion of the HIV antibodies to give distinct pinkish purple DOT(s) against a white background. The HIV TRI-DOT test is a visual, rapid, sensitive and accurate immunoassay for the differential detection of HIV-1 & HIV-2 antibodies (IgG) in human serum or plasma using HIV-1 & HIV-2 Antigens immobilized on an immunofiltration membrane. The test is a screening test for Anti HIV-1 and HIV-2 and is for in vitro diagnostic use only. Rapid antibody tests are qualitative immunoassays intended for use in point-of-care testing to aid in the diagnosis of HIV infection. These tests should be used in conjunction with the clinical status, history, and risk factors of the person being tested. The positive predictive value of Rapid Antibody Tests in low-risk populations has not been evaluated.
