What is viral load?
Living with HIV FAQ. Infectious Disease Consultants of South...A viral load test, or HIV RNA assay, measures the amount of virus circulating in your bloodstream at a given time. This gives us a better picture of how active your HIV infection is. High viral load values are associated with a more rapid progression to AIDS and indicate a need for more aggressive treatment. Additionally, the viral load will respond to changes in your medications within 2 weeks, so we can quickly assess how well the medicines are fighting HIV.
Related QuestionsPalmetto AIDS Life Support Services | Columbia SC | (800) 92...Viral load is simply how much virus is in the blood stream. Your doctor will order this blood test several times per year to determine if you should take anti-HIV medications or if your medications are working. It may be a good idea for you to track this number for yourself, too. When taking anti-HIV medications, some people achieve very low levels of HIV in their blood and have "undetectable" viral loads.Related Questions
VoyForums: HIV/AIDS NEWSThe viral load test measures the amount of HIV virus in your blood. There are different techniques for doing this: The PCR (polymerase chain reaction) test uses an enzyme to multiply the HIV in the blood sample. Then a chemical reaction marks the virus. The markers are measured and used to calculate the amount of virus. Roche produces this test. The bDNA (branched DNA) test combines a material that gives off light with the sample. This material connects with the HIV particles.Related Questions

Related QuestionsWhat is viral load? Why is it important?
Home PageViral load is the medical term used to describe the amount of HIV present in your bloodstream. This may range from a small amount to a large amount. Knowing how much HIV is present in blood shows how well your immune system is going to deal with the virus. You find out what your viral load is by having a simple blood test. The lower your viral load result the better.
Related QuestionsHOW ARE CHANGES IN VIRAL LOAD MEASURED?
VoyForums: HIV/AIDS NEWSRepeat tests of a blood sample can give results that vary by a factor of 3. This means that a meaningful change would be a drop to less than 1/3 or an increase to more than 3 times the previous test result. For example, a change from 200,000 to 600,000 is within the normal variability of the test. A drop from 50,000 to 10,000 would be significant. The most important change is to reach an undetectable viral load. Viral load changes are often described as "log" changes.
Related QuestionsARE THERE PROBLEMS WITH THE VIRAL LOAD TEST?
VoyForums: HIV/AIDS NEWSSome scientists think that only 2% of the HIV in your body is in the blood. The viral load test does not measure how much HIV is in body tissues like the lymph nodes, spleen, or brain. HIV levels in lymph tissue go down when blood levels go down, but not at the same time or the same rate. Viral levels in semen seem to be unrelated to blood levels. The viral load test results can be thrown off if your body is fighting an infection, or if you have just received an immunization (like a flu shot).
Related QuestionsWhat is the HIV viral load?
Chelsea and Westminster NHS Foundation TrustThis is a measure of how much replicating HIV is found in the circulating blood. In a HIV positive person this usually varies from a few hundred to a few million copies/ml. In patients on HIV treatment, the viral load is an accurate measure of how effective treatment is. The aim on treatment is to reach an "undetectable" level. Please note having an undetectable viral load does not mean the person is not infectious – he/she can still transmit HIV to others.
Related QuestionsQ11. If I am on antiretroviral drugs and have an 'undetectable' viral load; am I still infectious?
Frequently Asked Questions - Postive Action for Treatment Ac...Even if you are on treatment or your tests show that you have very low levels of HIV in your blood, the virus is never totally eradicated and you are therefore still capable of infecting others. Some drugs do not penetrate the genitals and disable HIV as easily as they do in the blood. This means that while you may have little active virus showing up on tests, there may still be quite a lot of HIV in your semen or vaginal fluids.
Related QuestionsIf my viral load is "undetectable" does that mean I am cured?
Welcome to Positive Healthcare - Florida - Frequently Asked ...No. Having an "undetectable" viral load means that there is very little virus floating around in your blood. This usually means that you are taking your medicines like you should and that the virus isn't reproducing, but you are still HIV+ and can infect someone else if you don't use safe sex practices.

Related QuestionsWhat does the viral titer or viral load tell me about my disease or treatment?
Welcome to NVGCThe level of virus in the blood stream or the quantitative PCR test for viral RNA in the case of Hepatitis C does not really tell us about the ability to resolve the infection with therapy, nor does it tell how severe the infection is. It may impart some risk of transmissibility i.e. the higher viral titers may be easier to transmit.

MultiGEN Diagnostics, Inc. : Frequently Asked QuestionsViral infections are mainly identified indirectly by detecting a patient's production of specific antibody (serology). But as antibodies are only produced a week or more after the start of an infection, results are delayed for a considerable period of time. In routine laboratories only a limited number of viral pathogens can be identified directly (usually with ELISA based methods), with positive results requiring a minimum concentration of the virus to be positive.
