Depends on exposure: Negative hep c antibody means no evidence of chronic hepatitis c infection. In acute hep c or in setting of immunosuppression, hcv viral load testing is helpful because hcv RNA can be detected within 2-3 days after exposure. Antibodies to hcv are detectable an average of 7-8 weeks after exposure. ...Read more
What is the test result range for both negative & positive for HSV antibodies IgM & igg? Ex. <0.9. .. Etc
Differs by lab: What you are asking is for the normal "reference ranges" for these tests. Reference ranges are established by each laboratory based on their testing equipment and vary from lab to lab. There is no universal reference range for these or other lab tests. You would need to ask for the range at the lab where the tests were run. ...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 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
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 exposure. (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
Any one: Depending on the concentration/titer of the antibody, it may be a false positive if it is low titer; if the titer is high it may portend an auto-immune disease like lupus or arthritis. However the person with ANA is still susceptible to all other diseases that affect other people with similar genetic background and environment. ...Read more
I have a test result of 1.8 for carcinoembryonic antigen, what does this mean? The test was one of many to apply for life insurance policy.
Carcinoembryonic: Carcinoembryonic antigen (cea) can be measured in the blood (plasma) and the normal range is usually reported as less than 2.5 ng/ml or less than 2.5 micrograms/liter. For smokers the normal cut off is 5 ng/ml. Age, infection, inflammation and some cancers can elevate the CEA level. ...Read more
Is an antinuclear antibody blood test result of 1.32 low, medium, or high? Is it something to worry about?
If 1:320, high-ish: Anas are reported as a ratio of how dilute the serum is when the antibody is still detectable, and the lowest ratio reported is usually 1 to 40, written 1:40. Meaning if you dilute the serum 40 fold, you can still find antibody. The next reading is 1:80, then 1:160, then 1:320. The number you write looks like it could be 1:320. That's a significant amount and might cause symptoms. Make appt w doc. ...Read more
Test result: CMV antibody IgG 38, it also states "current vs. Prior exposure unclear" why is it unclear? Am I contagious or not? Feel achy and ill
Need IgM test:
It's unclear because IgM levels are needed to determine recent vs. Prior infection.
A negative (CMV) IgM results suggest that the patient is not experiencing a recent infection.
Positive CMV IgM results indicate a recent infection (primary, reactivation, or reinfection)
Positive CMV IgG indicate past or recent CMV infection. May transmit to susceptible individuals through blood and tissue product ...Read more

Deciphering a thyroid hormone test result: is an antithyroglobulin antibody titer of 1:50 too high, or is it alright?
It depends: Antithyroglobulin antibody is not a thyroid hormone test. It tells you nothing about the function of your thyroid. It can indicate that you have autoimmune thyroid disease, but your level is not very high. Mild elevations are non-specific and occur more commonly in the population as we get older. Thyroid function is indicated by t4, tsh, and T3 (liothyronine) levels. ...Read more
