ELISA Test (Enzyme-linked immunoassay)
The enzyme-linked immunoassay (ELISA) is used to identify antibodies in the blood produced due to a harmful substance that has entered the body. This test is widely used to detect blood-borne viruses like HIV, HBV, HCV, and HTLV.
Four types of ELISA- Direct ELISA, Indirect ELISA, Sandwich ELISA, and Competitive ELISA.

Findings of ELISA test
The ELISA test helps identify the situations that lead the immune system to produce antibodies, which the swab tests cannot easily identify.
It helps find out about the viruses like HIV, HBV, HCV, and HTLV in the blood that lead the body to produce antibodies.
You must visit a doctor for abnormal findings and get a complete diagnosis and treatment.
Frequently Asked Questions
No, each ELISA can detect a specific antigen.
The plasma of the human body where the heterophilic antibodies are found is capable of binding to both the capture and detection antibodies used in capture ELISA by cross-linking with the assay antibodies and resulting in false-positive signals.
Typical ELISA test detection ranges from 0.1 to 1 fmole or 0.01ng to 0.1ng.
This test is recommended if you are exposed to HIV as well as to diagnose other infectious conditions.
Horseradish peroxidase (HRP) and alkaline phosphatase (ALP) are commonly used enzymes.
The test can be accurate by 99.9% when used in combination with the confirmatory Western blot test.
Specific antibodies bind to the target antigen by detecting the presence of antigens, and to get the correct value, the plate must be coated with the antibodies with high affinity.
When a person has some infectious conditions, the test determines if the patient has antibodies developed due to any infection.
The ELISA test is sensitive due to the binding characteristics of the antibodies.
It requires a small draw of blood, around 4 milliliters.
