There are several enzyme substrate combinations available for use in the ELISA detection step. The most common enzyme is horseradish peroxidase (HRP), which can cleave the substrate molecules ortho-phenylenediamine dihydrochloride (OPD) and tetramethylbenzidine (TMB), among others. Cleavage of both OPD...
There may be many skin tests performed, depending on the person’s age, symptoms and other factors. A positive skin test appears as a raised, red itchy bump, similar to a mosquito bite. The test is compared to the positive and negative controls, which are 2 other skin tests placed along...

The Western blot test is used to confirm positive results from either gel-electrophoresis or ELISA tests. The Western blot test can identify proteins more specifically and can rule out false positives. Diseases The Western blot test is generally used to confirm positive test results for human immun...
While a total IgE test measures the total amount of IgE antibodies in the blood, an allergen-specific IgE test measures how much IgE the body makes in response to a single allergen. Here are more key distinctions between these two tests:...
The article discusses the cross-sectional study which states that enzyme-linked immunosorbent assay (ELISA) tests have shown high sensitivity and specificity in determining seropositivity for herpes simplex virus II (HSV-2) antibodies in the U.S. However, they are less specific for HSV-2 and ...
What this lab and similar labs are doing is really important though. ELISA is used for diagnosis of so many different diseases. The more developed and accurate ELISA tests are, the better it will be for patients. So I have a lot of respect for his work. When I didn't understand any ...
