HIV test

Various tests have been used to detect HIV and production of antibodies thereto; some HTs shown below are no longer actively used, but are listed for completeness and context. See HIV, Immunoblot.
HIV tests
Culture The direct culture of HIV in the appropriate cell–human lymphocytes
IgA assay An immunoblot-type assay which allows the early diagnosis in infants of perinatal HIV infection
p24 antigen The measurement of HIV's p24 antigen by immunoassay, confirmation by neutralization; very low sensitivity
PCR Amplification of HIV nucleotide sequences by PCR, used to confirm indeterminate Western blot results
RNA testing
Western blot An immune assay which detects specific antibodies to HIV antigens, including p24–often the first antibody to appear; low-risk individuals with a persisting indeterminant Western blot at 3 months may be regarded as negative and require no further followup

Patient discussion about HIV test

Q. The HIV test came back POSITIVE! My very close friend 'Demonte'. One day in December as he was returning from a business trip, his wife met him at the airport with terrible news. During a routine pregnancy check up, her doctor had administered an HIV test along with other blood-work. The HIV test came back POSITIVE! The doctor wanted to begin administering drugs immediately but the cost of these drugs here when compared to their family income was prohibitive. I helped him with some of my savings. He already sold his favorite sentimental car to save his precious wife. Now i want to know is there any NATURAL medicine to cure this? Hope it costs less and available.

A. there are no effective natural remedy for HIV. the medications are very hard ones that try to control the virus from spreading (cannot eliminate it though). no herbal remedy or nutrition change will do that.

Q. what tests do i need to do to check that i don't have HIV? and how long does it take to get an answer? i had unprotected sex with this girl i met , and i am really afraid , things just happened really quickly and we had sex and i did not use condom , what should i do ?

A. If you think that you have HIV or you just want to be sure, you should go to your nearest clinic and get tested. They will know what tests you would need to take. Some clinics even do this kind of testing for free. Here is a website on different testings a nd prices: You should always use precaution when having intercourse. You can never be to safe. Hope this helps.

In addition, there are two types of viral tests for HIV that measure the amount of virus in the blood directly: the p24 antigen test and the RNA viral load test.

If this does not confirm the result of the first test, it will be followed with a P24 antigen test to retest the antigen component.
There are also two viral tests for HIV that measure the amount of virus in the blood directly: the p24 antigen test and the RNA viral load test.
"Today's approval is particularly significant since Procleix can be used as an alternative to the currently-licensed p24 antigen test for HIV-1.
The most common tests used to diagnose PHI are the quantitative HIV RNA (viral load), which uses polymerase chain reaction to detect the presence of HIV, and the p24 antigen test, which detects a viral protein and indicates ongoing viral replication.
The results showed that while the p24 antigen test has a specificity of 100% (there were no false positives), it only has a sensitivity of 88.7% (5 of the 40 PHI patients were not detected by the test).
Yet blood banks may never use the p24 antigen test because it would cost a lot, yet save few additional lives, he and others assert.
The alternative would be a p24 antigen test in the case of indeterminate results.
The test for these proteins is called the p24 antigen test. Also, a doctor can check for HIV in the blood by doing a viral load test.
During 2001 and 2005, HIV 1 and 2 antibodies (with a window period of about 22 days) and HIV p24 antigen tests (with a window period of about 16 days) were used to screen all blood donations.
