What Is an ELISA? An enzyme-linked immunosorbent assay (ELISA) is a specific type of enzyme immunoassay (EIA) that allows for the quantitation of a molecule of interest using antibodies. Antibodies are used to specifically identify the analyte (eg, peptides, proteins, antibodies, small molecules...
An antibody assay is a type of lab test that is used to check for the presence of antibodies in a sample of blood, urine, tissue...
Sandwich ELISA assays are the most commonly used assay test. In a sandwich ELISA assay, two specific antibodies sandwich an antigen or antibody of interest, known as matched antibody pairs. The capture antibody is coated on a microplate. Target proteins from the sample bind to the captured ...

What is an IgE Blood Test? An IgE blood test is a particular type of blood test that measures the levels of immunoglobulin E (IgE) antibodies in a person’s blood. IgE is a specific type of antibody that the immune system produces in response to allergens or other perceived threats that...
What is the best test for Lyme disease? Evidence-Based Answer: If a patient develops erythema migrans after a tick bite in an endemic area, no testing is required. Simply treat the patient. If the diagnosis of Lyme disease is uncertain, obtain a sensitive enzyme-linked immunosorbent assay (...
