In blood, what you are checking for is viral antibodies not HIV RNA. Your body produces antibodies to antigens (e.g. HIV proteins) to combat foreign bodies.
The first test for HIV is called ELISA. This is a sensitive test that will be positive for many people that are not infected. The reason for this is to capture everybody that could POSSIBLY be infected. This is done to rule out those that do not have HIV.
The next test that follows ELISA is a Western Blot test. This is a specific test for HIV viral proteins. This test is to rule in those that do have HIV.
If you have an acute infection of HIV, you may not have the antibodies that are produced for the tests above. It takes approximately 2 months for antibodies to show up in your blood. In this case you can do a viral load count using PCR.

Is HIV RNA?
Yes, HIV is an RNA virus. However infectious HIV is more than just RNA.
What is the meaning of HIV not detected?
"HIV not detected" means the HIV test is negative.
What is the meaning of not detected HIV test result?
The meaning of a not detected HIV test result means that the viral load can not be detected. If this is the first HIV test, you need to retest in 3 months. If you have already have been diagnosed with HIV, continue taking the prescribed medication.
When human immunodeficiency virus HIV attaches to a host cell what genetic material is released into the cell's cytoplasm?
Within the HIV capsid is the genetic material RNA along with two reverse transcriptase enzymes to copy the RNA into DNA inside the invaded cell.
Hi Peter, I understa?
Hi Peter, I understand that you are very frightened. I would be happy to answer your question. Whether or not the negative result is reliable or not depends on what the test was. There are two ways to test for HIV: antibody and RNA levels. The most common and widespread way of testing for HIV involves testing the blood for levels of antibodies against HIV. If a person is exposed to HIV, his or her body will develop antibodies against the virus to try to fight it off, and these can be detected in the blood. Antibodies can take a relatively long time to be detected (2-8 weeks or even longer in some individuals). RNA testing measures HIV directly (the virus itself instead of the antibodies against it), and this can return positive much more quickly than antibody testing-typically, 9-11 days after HIV exposure. So, if you were exposed to HIV 11 days ago, you would most likely not demonstrate any antibodies until 2 weeks after the event at the earliest, but the virus would most likely be detectable by now. Since your doctors told you to "not worry", I suspect they checked your HIV RNA, not antibodies to HIV. For your peace of mind, you can ask your doctor the type of test that was done-if it was the antibody test, you will need to wait several months and be tested again. But if it directly tested for HIV and was negative at 11 days, odds are you are in the clear.
Is the HIV virus double-stranded?
No, HIV is a retrovirus - it has a single-stranded RNA genome.
What would the HIV viral sequence of AUCUU be converted to and by what enzyme?
The HIV virus is an RNA virus, so you know the sequence AUCUU is the RNA sequence. (You also know it is RNA because it contains uracil.) HIV is a retrovirus, so its RNA will be transcribed to DNA by the enzyme reverse transcriptase and then inserted into the host's genome. The RNA sequence of AUCUU would be transcribed to TAGTT.
What does it mean if HIV antibodies are detected by the western blot analysis?
It means that the person has HIV.
Is HIV virus alive?
HIV is a virus. Because it is a retrovirus HIV has 2 fragments of RNA Moleculehiv is rna virusNo HIV attacks t cells which produce white blood cells. White blood cells attack infections and disease and viruses etc. so with no white blood cells or few of them no virus can be fought off, so something like a cold is the thing that actually kills you.hiv contains rna, the rna i the virus go into ribosomes and effect the human body
Example for bacterial RNA viruses?
Flu and HIV
Is a HIV virus an exemple of DNA containing virus?
HIV is an RNA-virus. It does not contain DNA.
What is the HIV window test?
The window period with respect to HIV testing is the time of infection, until the time it can be detected during testing (which means antibodies are being produced from the body's immune system).
