On Mitochondrial antibody test by Elisa, 0-20 neg,21-24.9equivocal, 25&>pos? would a level of 29 be a low positive?
Anti-DNA antibodies: Simple blood tests can be performed to test for anti-dna antibodies. Usually the screen is started with a basic ANA test which can then be followed with more specific antibody testing to determine if a specific disease can be identified. Of course, symptoms must also correlate since we do not simply provide diagnosis based on lab findings. ...Read more
I had my 5 weeks 3 days ELiSA antigen antibody HIV test and came negative, how accurate is it and can I be assured while waiting for my 3 months test?
Is there a test similar to the elisa, or the IFA that detects higher than normal levels of antibodies across a wide array of third world diseases all at once with one test? Basically an antibody test where mass cross-reactivity is preferred?
H. pylori infection: .. which causes gastritis with symptoms of early satiety, abdominal pain, heartburn. If you are symptomatic, then you will need the treatment. If you are not symptomatic or have responded to treatment already, then your test result indicates ongoing antibody production (normal immune response to previous infection) and no treatment is required. Good luck! ...Read more
Is HIV 1/2 antibody combo(cmia) test as accurate as ELISA test? Also if the combo test at 75 & repeated at 100 days concl. If they are non reactive?
HIV testing: Yes the combination of testing for p24 antigen and antibodies to HIV 1 ; 2 is quite accurate, even if done using techniques other than elisa. The negative results at >3 mos after exposure make it almost certain that you are not infected with this virus, although there have been very rare cases in which antibodies were not detected until 6 to 12 mos later. You are probably fine. ...Read more
I have read in medical journals that opiates have been shown to have a negative effect on the bodies ability to produce antibodies. Would this make a person less likely to test positive for a disease using the elisa test if they had to go on opiates?
Not aware: Do you have the reference on the opiate effect since I am not aware of such link. However people may potentially have a depressed immune system when they suffer from a chronic illness or pain. Nonetheless, I don't expect opiate per se to affect testing on antibody either in quantity or quality . ...Read moreSee 2 more doctor answers
Yes.: The test can technically be done in less than an hour. However, time taken for blood draw, transportation to the lab and if the tests are batched, will all add time and it may take a day or so to get the results. ...Read more
Is ELISA test for HIV 1 & 2 antibodies conclusive after 8-9 weeks of exposure? Does NON-REACTIVE mean NEGATIVE?
ELISA for HIV: The ELISA test is not conclusive after any amount of time. The ELISA is a screening test and if it comes back positive, a Western blot will need to be done. Non-reactive is a good thing to be and it does mean that you are negative for HIV virus. Although there is a window period when you can have the HIV virus but still have a nonreactive result. Another test may be needed in that case. Suerte ...Read more
Are the results of hiv elisa test effected by orlistat consumption during the past 6 months. would it hamper antibody formation thus the test result.?
Does presence of dsdna antibody (ELISA 120 U) indicate lupus? the lab reference range was normal upto 200U and ANA titre is low with total ANA 55. Thx
Hi doctor i just have question 14 weeks from elisa test antibody hiv-1and hiv2 was negative is that conclusive and i tested also oraquick came up negative as well. do i need further testing?
Both are conclusive: Since the ELISA included HIV2 as well as HIV1, it is a "third generation" antibody test. Those tests are virtually 100% conclusive by 6-8 weeks after exposures. (No need to wait 3 months; that's old news.) The Oraquick oral fluids test is conclusive by 3 months. Therefore, your tests are definitive and prove you don't have HIV, assuming no more recent exposures. You don't need any more tests. ...Read more

HCV RNA pcr- not detected
18 years old No risk factors
What is my outcome?
Normal: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, you are not likely to have hepatitis C. Why was the test done in the first place? Unrelated to your question: Practice safe sex. Get HPV and Hep B vaccines. ...Read more
How long do antibodies remain detectable in the blood? I had a clear ELISA for Lyme disease after recurring lightheadedness and brain fog after a possible bite when hiking in the uk but the test was a good 10 months later -would it still be reliable?
last for years and some others (such as chicken pox) last a lifetime.....It is VERY unlikely that you had a Lyme exposure if the tests are negative in 10 months!
Hope this is helpful
