I am very confused about my HSV test results. Apparently what was tested was "HSV 1/2 IgM, IFA; HSV 1 and 2-specific Ab, IgG."
The results state as follows:
HSV 1 IgM, IFA result 1:80 (high)
HSV 2 IgM, IFA result 1:40 (high)
REFERENCE RANGE <1:20
INTERPRETIVE CRITERIA:
or = 1:20 Antibody Detected
It also states "the IFA procedure for measuring IgM antibodies to HSV 1 and HSV2 detects both type-common and type-specific HSV antibodies. Thus, elevated titers to both HSV 1 and HSV 2 may represent crossreactive HSV antibodies rather than exposure to both HSV 1 and HSV 2."
It goes on to give this information:
HSV 1 IgG, Type Spec <0.91 (equivocal 0.91 - 1.09)
HSV 2 IgG, Type Spec <0.91 (equivocal 0.91 - 1.09)
Note: Negative indicates no antibodies detected to HSV-1, HSV-2. Equivocal may suggest early infection. If clinically appropriate, retest at a later date. Positive indicates antibodies detected to HSV-1, HSV-2; coinfection cannot be excluded without type specific testing.
My questions are these: What is "IFA"? I have read a lot about IgM testing being inaccurate, but from this, I really can't figure out if the IgG was tested or not. It seems like if it was, it was equivocal.
Can someone please help me interpret these results? My nurse practitioner was not very specific in giving me the results over the phone, which is why I requested a copy. She said it looks like I was "recently exposed." I asked her how reliable the test was, and she said she thought it was "pretty reliable." I also have a blood disorder, antiphospholipid syndrome, so I have an anti-S antibody in my blood as it is. I wonder if this could alter the test results.
Any help/explanation for these results would be greatly appreciated. I asked her if she would look into the possibility of a false-positive (as I have had absolutely no symptoms) with the antiphospholipid syndrome. That was 2 weeks ago, and she still doesn't have an answer for me. This is really putting a strain on my life. My test was done just 2 days shy of a month ago. Should I get retested with a different type of test?
Thanks!
