widal test (slide & tube) procedure
 
14:22
Widal test is still a common way of diagnosing enteric fever cases in several countries. Although tube agglutination is the standard, some manufacturers have adapted it for slide agglutination. This video shows qualitative as well as quantitative test on a kit that can be used for both slide as well as tube agglutination. Procedure displayed here is as per manufacturer's directions. Procedure of tube agglutination test varies across kits. Kits designed exclusively for tube agglutination have different procedures.

Widal test
 
02:46
The Widal test is a presumptive serological test for enteric fever or undulant fever whereby bacteria causing typhoid fever are mixed with serum containing specific antibodies obtained from an infected individual. In case of Salmonella infections, it is a demonstration of the presence of O-soma false-positive result. Test results need to be interpreted carefully in the light of past history of enteric 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 it 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 easily identified on differential media such as Bismuth sulfite agar. Often 2-mercaptoethanol is 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). This video is targeted to blind users.

Salmonella typhi IgG/IgM Test
 
02:33
***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.

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

(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.

It was first described in 1916. 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.

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 -~-~~-~~~-~~-~-

Coombs Test or Antiglobulin Test - Direct and indirect

Coombs Test or Antiglobulin Test - Direct and indirect This is a teaser video. Watch the complete lecture in the member's area at https://www.DrNajeebLectures.com A Coombs test (also known as antiglobulin test or AGT) is either of two clinical blood tests used in immunohematology and immunology. 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—that is, a condition where the immune system breaks down red blood cells, leading to anemia. The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's own plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent"). If the red cells then agglutinate, the direct Coombs test is positive, a visual indication that antibodies or complement proteins are bound to the surface of red blood cells and may be causing the destruction of those cells. The indirect Coombs test is used in prenatal testing of pregnant women and in testing prior to a blood transfusion. The test detects antibodies against foreign red blood cells. In this case, serum is extracted from a blood sample taken from the patient. The serum is incubated with foreign red blood cells of known antigenicity. Finally, anti-human globulin is added. If agglutination occurs, the indirect Coombs test is positive ─────────────── DR. NAJEEB LECTURES ─────────────── Dr. Najeeb Lectures are the World's Most Popular Medical Lectures.
