How accurate is NAAT urine tests for chalmdyia and is it possible to get two false negatives in a row?

How accurate is NAAT urine tests for chalmdyia and is it possible to get two false negatives in a row?

Testing: The negative predictive value of chlamydia NAAT urine tests are in the 99% range. This means that a negative test very likely indicates that there is no disease. 2 negative tests are even more likely to indicate that there is no disease. Nothing is impossible, but it would be HIGHLY unlikely that there would be 2 false negatives in a row. ...Read more

What is a naat HIV test? Is it accurate?

What is a naat HIV test? Is it accurate?

NAAT HIV testing: Again you keep asking about antibody testing. It is accurate if enough time has passed for the body to create potential antibodies. Usually up to twelve weeks after exposure. But tests after twelve weeks will of course be accurate.

It is just mind blowing that anyone is offering you these tests when there is a 100% accurate test that does not require such a length of waiting. ...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

Would a NAAT swab test show positive for chlamydia 3 days post possible exposure?

Would a NAAT swab test show positive for chlamydia 3 days post possible exposure?

A bit too early: The exact time for reliable chlamydia testing by NAAT isn't certain, but 3 days probably is a bit early. A negative result would be somewhat reassuring, but probably not conclusive. It would be safer to wait until 5 days or so, unless there is some urgency (e.g. if you have abdominal pain or other symptoms of a complication like PID). ...Read more

After how many weeks of Exposure would the 4th gen HIV test be more accurate than a NAAT or RNA test?

It depends...: Unless the exposure was especially high risk, e.g. unprotected non-oral sex with a KNOWN infected person, NAAT testing should not be done at all. The 4th gen blood tests usually are positive at 2-3 weeks and always by 4 weeks. That's probably what you need. If the risk may have been genuinely high (e.g. unprotected anal with another guy), don't test online; see doc or clinic in person. ...Read more

Help, I tested + for GC on a pap smear NAAT, got treated. The next day I got retested and it came --. My bf of 3yrs tested --. both no sympts, fals+?

Gonorrhea tests: This is a tough issue where one test says positive and the other negative. Our human tendency is to believe the result that we like but for safety reasons it is usually safer to treat based on the positive STD screen. NAAT is great for gonorrhea & chlamydia testing but false positive tests can occur. ...Read more

Does the HSV swab NAAT test conclude the site of infection? In theory, if a lot of discharge was on the swab, could it not detect infection elsewhere?

Does the HSV swab NAAT test conclude the site of infection? In theory, if a lot of discharge was on the swab, could it not detect infection elsewhere?

Immaterial: The test will detect the presence of HSV at the site from which the swab was taken. However, HSV has access to your whole body and it does not much matter where the primary site of infection is or was.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, 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.

How accurate is urine std testing using NAAT?

How accurate is urine std testing using NAAT?

Here are some. ..: In the US, whatever approved by its FDA & marketed is considered to be reasonably safe, effective, & accurate although some frauds may still exist. But in comparison, that is best we can come by due to its highest transparency; of course, nothing is perfect and behind what we know always still hides a lot what we don't know. So, NAAT testing is good enough for daily use. More? Ask Doc timely. ...Read more

No false results NAAT. 4 neg tests/retests for chlamydia before/during pregnancy. Now 2 positive after birth no sex of any kind at all between how?

A few possibilities: It is hard when people have one positive and one negative result on a test. Possible interpretations are: 1. The neg tests were false and the + test is correct 2. The neg tests were true and the + test is incorrect 3. Both are correct and you acquired it between tests. You and your doctor who know you can determine that best course of action. Consider testing your partner. ...Read more

Naat HIV test has the shortest window period of only about 2 weeks. Does this length apply even to those who take longer than average to seroconvert?

Dr. Ziad Akl Dr. Akl
2 doctors agreed:

Yes: The two things have nothing to do with each other. Naat looks for the viral nucleic acid, while seroconversion is the appearance of antibodies against the virus. ...Read more

If I had HIV 2 would my HIV 1 western blot be intermediate after 1 year of exposure? I got a negative western blot and naat test for hiv.

MIstreatment?: Any doctor who diagnosed you with a positive HIV test should be sending the HIV RNA test and not just the western blot test. You are in the U.S. You need a smarter or more experienced doctor for this. You have been left out to worry for over one year and it appears not once been given the right test. I don't know your personal life story and what your exposure was. ...Read more

HIV: Yes, this is worth further investigation. A common cause for biologically false test results may be autoimmune diseases, syphilis, and other illnesses. If you want to exclude HIV disease would suggest a pcr for HIV rna. Expensive but definitive. Good luck. ...Read more

2 false pos ELISA HIV tests, all 1 1/2 years post exposure. Neg western blot, ifa, naat and 2 neg oraquick home tests. What is my HIV status? Help!

2 false pos ELISA HIV tests, all 1 1/2 years post exposure. Neg western blot, ifa, naat and 2 neg oraquick home tests. What is my HIV status? Help!

Likely negative: There is typically a "window" of 3-6 months after exposure where you could be HIV positive but test negative. Since you didn't get your testing until well after that, i'd say the confirmatory tests (western blot, ifa) are what you should go by. The elisa is very sensitive and can have false positives- that's why we rely on the confirmatory tests. I would consider your status to be negative. ...Read more

Wht cause a false pos ELISA HIV test with neg naat and western blot? 2 neg oral fluid rapid results. After 1 year exposur. Ihave autoimmune hypotyroid

No answer: Please. How many times are you going to ask the same question. There is no right answer here. Your body has something triggering the simple HIV antibody test to be positive. It is not HIV causing this symptom. In the future you should avoid these tests and get the better test. You have been given this answer numerous times. It is time to move on. ...Read more
