antibodies against the antigen
Assaying the samples in triplicate is another control. If you do not get the same result in all triplicate wells, you have a problem with your experimental technique or you have made a pipetting error. In a clinical laboratory, the experiment would have to be repeated.
For this test, the patient is seated in a darkened room and recording electrodes are placed near the eyes. Warm and cool water or air are gently introduced into the each ear canal and eye movements are recorded.
there is only one way to find out if something is real or not. when you test it to find out if its fake or not, put it in direct sunlight and leave it there for a little while.

Indirect is used to test for ANTIBODIES and direct is used to test for ANTIGENS. For example, Indirect ELISA is used to test for HIV antibodies.

The Western blot test is used to confirm the results
ELISA is a technique used to determine the presence of antigen or antibody in a sample. ELISA is used in diagnosis of HIV... ELISA is of three types: direct method, indirect method and sandwich method. The principle of three methods are same.
direct fluorescent antibody test
The ELISA test is usually the first test given; quick results and inexpensive. See the related link.
Western Blot Test: is a blood test that produces more accurate results than the ELISA test.
There is only one test that can give the accurate results for HIV. The only test that can do this would be the Elisa test.

The AGID test is the agar gel immunodiffusion test and ELISA is the enzyme-linked immunosorbent assay. Both test for the presence of certain proteins (called antigens) by binding them with antibodies.
An Elisa Test is used to test for a substance using antibodies for colour change. The test has been used in medicine and plants. Performing the test involves using an antibody and enzymes.
Nothing is better then ELISA and CLIA methodology, NAT testing also does not eliminate the window period but only reduces it. The cost is much higher then ELISA updated: western blot test
