+ gonorrhoeae DNA amplification test, but, neg. Amp RNA test(source urine). Do they have gonorrhoeae? Is one test more reliable?
Complicated: Although these tests are very sensitive there are false positive results because of the potential presence of other benign species of neisseria. If you had to compare the two it would be without much relevant data. Bacterial culture will provide both a definitive diagnosis and allow determination of antibiotic sensitivities. ...Read moreSee 1 more doctor answer
C.trachomatis RNA TMA Result: Detected. Standard range: Not detected. Test performed using the Aptima Combo2 (R) assay gen-probe(r)
You have chlamydia: "Detected" means the test found chlamydia -- i.e. a positive result. Return to the doctor or clinic where the test was done for treatment. (If you tested yourself at a lab, see a doctor or clinic ASAP.) Your current or recent sex partner(s) also need treatment. Good luck! ...Read more
Elisa hbsag was negative in may 2013 befr my dnc.Now another lab test shows hbsag positive during blood test fr fertility treatmnt.can tis be true?
Yes, but...: If a person converts from HepBsAg negative to HepBsAg positive, her primary care doctor can evaluate her and order a larger panel of Hepatitis B tests to see what is going on. If HepBsAg is confirmed to be positive, the patient is contagious with HepB viruses (which are spread through blood and bodily fluids contact). That means all household contacts should have their HepB immunity confirmed. ...Read more
Pt in Kuwait, low risk sex activity. PCR equivocal. Repeating. Other tests neg. his question is this test done the same US, Germany, London,test +/-?
Depends: PCR is very specific and sensitive, but all tests have a false positive rate, and for PCR, the number is very small. I don't think it should matter where the test is redone as long as the technique is the same or similar ...Read more
4 month neg HIV test brief unprotected encounter with female is this conclusive 3 2ndgenantibodies test neg three rapids neg and a PCR undetectable ?
Probably, clarify.: The standard HIV test is first the elisa, for screening, and then the western blot for specificity. The western blot is done if the elisa test is positive. Nucleic acid tests, like pcr, are used in testing donor blood. Although the basic tests can be extermely accurate there is a chance of false negatives due to the up to 6 month seroconversion time it takes to make antibodies. See my comment. ...Read moreSee 2 more doctor answers
Enhanced chemiluminscence assay fr HIV (-ve) result conclusive after 14 months. Earlr immuno assay (-ve) at 17 days, RNA PCR (-ve) at 33 days. Pls adv?
Negative HIV: I understand that you've had a series of negative labs for hiv. I've glad to hear this. Very rare people never develop the antibody, and if you are still very afraid, see if you can get another pcr and be done with this. From now on, think about barrier protection both for yourself and whoever you love -- it's gentlemanly & may enhance your enjoyment in other ways. Good luck. ...Read more

Is the dna, sda chlamydia test unreliable? It showed me as a negative but i cmae up positive in the rna, tma test. How come?
Generally reliable: Both tests have very high sensitivity and specificity; however, the dna sda test can have false negatives if there is an inhibitor present, such as a high white count in the urine or blood. The rna/tma test is less subject to this, and due to the positive screen and risk/benefit ratio, i would recommend treatment. ...Read more

Hw reliable is the elfa test for hiv.I hv done it after 4 years zat i had unprotected sex.My result is non reactive for hiv. Is ELISA and elfa z same?
Likely negative: I'm not familiar with elfa. I thing you mean enzyme-linked immunosorbent assay (elisa) is a test that uses antibodies and color change to identify a substance..Namely HIV antibodies in your blood. It is very very accurate. After 4 years i can say with 100% confidence you do not have it. ...Read moreSee 1 more doctor answer

4 month PCR RNA HIV negative and 4,5,6 month 4th Gen Abbott Architect AG/AB negative, should I retest? Am I HIV free? How PCR works? Is it reliable?
Since you are neg.: for both the HIV virus itself (PCR RNA) and the antibody to HIV (AG/AB),, you can be confident that you don't have HIV. PCR tests for HIV RNA by multiplying the number of RNA fragments to detectable levels. AG/AB testing detects your immune systems response to HIV. Taken together, all these NEG tests are very reliable. Time to focus on behavior that may have put you at risk. Dr. Anne. ...Read more
Accuracy of ELISA: The elisa test is 99+% accurate (sensitive and specific) in individuals who have had the infection long enough for the assay to pick it up. For the 3rd generation tests used today, it can reliably detect individuals infected w/hiv at approximately 15 days. The 4th generation wh/tests for HIV antigen and antibody may show results even sooner. Always have testing done at a reliable certified lab. ...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!
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
