Are RNA tests accurate for testing for HIV?

Are RNA tests accurate for testing for HIV?

Yes, but...: The HIV RNA tests are checking for the presence of certain parts of HIV. When positive, it can give us an idea of how much HIV is present. Most of the time, when positive, it highly suggests HIV infection. However, in rare instances, there can be false positive tests, which mean that a positive test may represent something else, not HIV. Thus, the best test for HIV is a standard HIV antibody test. ...Read more

How accurate are the oraquick hiv in home tests? I performed a test 3,6,9 months post exposure. All negative. Is it accurate as a blood ELISA test?

Oraquick: accurate, but as for every test there is limitation, a positive test means that an antibody against HIV is detected; However more test is needed to confirm it, a negative test does not rule HIV , specially if the test is performed during the window period of HIV detection ( window period: first 6 weeks after HIV infection, when there is not enough antibody is produced for the test to detect it) ...Read more

Bloods taken at clinic, sent off to lab and then a few days. Negative. Do these tests look for antigens? For HIV

Bloods taken at clinic, sent off to lab and then a few days.  Negative. Do these tests look for antigens? For HIV

Not necessarily: The laboratory will only test the blood for the items ordered by your doctor. If an HIV test is not ordered, the lab will not test for HIV. If you have any concern, you may ask your doctor for the HIV test. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more

What blood tests should be done to check for arthritis(all types)&rheumatic pain?Please list all tests needed&would taking Penicilin influence results

Not enough room: 400 characters won't list the labs that a mediocre rheumatologist in a fishing expedition could order. What I can tell you is that no specialty has more labs, and perhaps depends on them less, than rheumatology when it comes to making decisions about management. Penicillin won't affect them. Hoping you get a proper diagnosis. Best wishes. ...Read more

Why do so many doctors on Health Tapp recommend NAAT tests for HIV testing when HIV professionals recommend the 4th gen test as a better test.

It depends...: You need to read the context of each question. Which test is "better" depends on the clinical situation. Indeed 4th generation (antigen/antibody) tests usually are sufficient and should be the usual recommendation. But NAAT for HIV RNA or DNA (in addition to antibody testing) is proper when the risk is especially high or if there is clinical suspicion of acute retroviral syndrome (ARS). ...Read more

Are all amnio tests sent away for testing?

Not all.: At baylor college of medicine, we are privileged to have one of the preeminent genetics departments in the United States, so our amniocentesis results are all obtained in-house. Most practices, however, do need to send the amniotic fluid specimens they collect to outside genetics laboratories. Keep in mind that tests such as sequenom's maternit21 will render amniocenteses obsolete pretty soon. ...Read more

How many blood tests are taken to test for rheumatoid arthritis?

How many blood tests are taken to test for rheumatoid arthritis?

Basic two: Rheumatoid factor (rf) and cyclic citrinullated peptide (ccp) are the two tests that help confirm a diagnosis of rheumatoid arthritis. Other tests are done to measure inflammation, determine which drugs may be used, etc. Note: the rf and ccp only help confirm the diagnosis. The presence of an antibody does not definitively make the diagnosis. Also, persons may have RA and be rf and ccp negative. ...Read more

Why would urine be used to test for HIV and not blood? How accurate is urine for testing for hiv?

Why would urine be used to test for HIV and not blood? How accurate is urine for testing for hiv?

Blood is optimal: Blood tests are more sensitive, but antibodies are also present in the urine and collecting urine specimen is easier than collecting blood. Oral fluid can also be tested for HIV antibody. A positive urine screening test, like a blood screening test would need confirmatory testing, generally by testing blood. Urine can be used for confirmatory testing but a negative result may not be reliable. ...Read more

Probably twelve weeks is a good standard for them. HIV is twelve to twenty- four weeks unless you have access to the RNA test and then that is 21 days post exposure. ...Read more
