Do you know what is IFA? What about HIV? You know it well, don’t you? So, what is the correlation between the IFA and the dangerous virus? A tissue sample for the presence or absence of the HIV-1 virus is examined by doing an IFA or immunofluorescent assay HIV test. Blood drawing or plasma samples from the patients are involved in this test. And they are allowed to undergo laboratory analysis. So, what is the purpose? The purpose of this test is to verify detectable levels of the antibodies which is made by the immune system against the HIV.
After a positive or inconclusive result has been returned by ELISA test or the more standard western-blot test, then IFA test will be used. This type of test for the first-step screening procedure for the HIV virus does not regularly executed by a doctor. When you want to read a result, you should be sure to ask for help from your doctor or a professional who specializes in sexual health.
If the IFA testing needs your blood, the doctor will ask you to give your blood or plasma sample. If you have any questions regarding the techniques used when conducting an IFA HIV test, you should not hesitate to ask your doctor. You will see that there is a certain antibody to the antigens which is generated against the HIV-1 virus during the IFA testing. One of four processes is usually employed by the antigens, and these are heterogeneous, noncompetitive, homogeneous-immunoassay, and/or competitive testing. This test cannot be used to discover the antibodies which are formed to fight the HIV-2 virus because it is only limited when you read the presence of HIV-1.
Also, you should ask your doctor to give an explanation about the protocol specific to the lab to finally finish the testing on your sample. You have to present a precised amount of HIV-1 antigen prior to concluding a test reactive or positive. And a follow-up test should be undergone if positive results are given by your IFA test.
