[Question #8099] Dr. H. Hunter Handsfield and Dr. Edward Hook

I left Terri out the subject because I asked her a question on her website West Over Heights.

I’m 24 year old and female. I’ve only had one sexual partner before in a monogamous relationship. The last time I had intercourse was approximately March 15, 2020. We exclusively used condoms but, had unprotected intercourse (with an IUD inserted) approximately 2-3 in 1 year and 4 months of dating.  I was recently tested for HSV I and II. I tested negative for HSV I on all lab tests, but positive for HSV 2. My doctor noted that being HSV I negative but, HSV II positive is odd and “uncommon.” What do you think of that? Is being negative for HSV I but not HSV II really uncommon or unlikely? Could there be some kind of interference happening with HSV types making HSV II come out positive?


I do not have symptoms of HSV II. No scabbing, soreness or anything like that. 


My scores for HSV II IgG were 


2.43  - June 17, 2021 (LabCorp)


(My GYN did not call me with the results. I had to call her several weeks later and only then did she disclose my results. The same day, I got my first results from June then did I begin to panic and get several follow up tests at different locations) 


2.28 - July 28, 2021 (Quest Diagnostics)  


2.55 - July 28, 2021 (North Well Health Laboratories)



I understand these scores are low and the CDC recommends retesting and so that is what I did with the following test in June.


I just have this feeling that my it’s just so unfair given I waited to have intercourse for the first time at 22 years old and already probably an STI. I feel like I was not given a chance. I just want to know how likely it is to whether my results are false positive? I’ve come to accept them as accurate since I’ve taken three tests. They are in the low range but, I just don’t want to get my hopes too high. The other thing that I find weird about these result is that I completely remember having cold sores when I was a kid. Not as an adult, but as a child I completely recall getting cold sores. Despite this, I tested negative for HSV I.


I’m ordering a Western Blot and plan have that process completed by the end of the summer. I have also scheduled a eVisit with Terri.



Given my sexual history, or lack of sexual history, does it seem likely this could be a false positive? Also does the time period from my last encounter, have any significance on the probably that this is in fact an accurate test result? Assuming I would have contracted HSV II sometime during our relationship, does that mean my lab result score would have been higher since I would have had the virus longer? My doctor’s are basically telling me to accept the results or take the Western Blot at my own “risk” given it’s so expensive.


Also, I don’t know if this matters or not but, I am a black person with both parents that immigrated from West Africa (Ghana) and I am first generation American. I’ve read that IgG is less accurate on Africans - which I am. Does getting the Western Blot from University of Washington seem worthwhile?



Does my ethnic/racial identity along with low-is score (between 1.1-3.5) give me some semblance of hope that I could potentially be negative with the Western Blot?


Thanks

This is certainly not our usual way of handling things on this site - I answer the herpes questions and Drs. Hook and Handsfield all the other STI questions.  But since you've posted on my website already, we will make an exception this time.  I've not yet seen your post on my website but will be looking at it today.  In summary, for those who don't read my website but do read here, I think a false positive is highly likely.  Both because the index value falls into the low positive range AND because your parents immigrated for West Africa and we already know the IGG test in the African population is unreliable. 

Now I will leave this to either Dr. Hook or Dr. Handsfield.  I've have written to both, asking one to respond

Welcome to our Forum.  As Terri told you, this is a bit unusual but, as per her request, I will be replying.  Terri and I have communicated about this and I agree entirely with her assessment and advice.  Sadly, false positive herpes blood tests are all too common and given your epidemiological circumstances it is quite possible that your results are falsely positive.   Repeating the tests you have already done will be of little benefit.  The best way to sort this out is to get a Western Blot assay from the University of Washington as Terri has suggested.  As to the “value” of getting a Western blot, that of course is a personal choice.  My guess is that, if you do get it, you will find that you  do not have HSV-2.

I hope this perspective it helpful.  I wish these tests were better.  EWH

Thanks so much, Ned, for responding on this post.  She and I have an appointment set up in August, I believe.  I hope when she gets her western blot results, she will post them here.

In one of my labs, my RPR came back reactive 1:1 despite my Treponema test results coming back nonreactive. My provider recommends I visit an infectious disease specialist - which I will. Another provider I visited  for a second opinion said that the RPR being reactive and Treponema coming back negative "does not make sense." A family member who is a health care professional, nurse practitioner, said the test should be repeated. Given RPR is a nonspecific test for antibodies, does this suggest an immune response to HSV-2? Does the RPR being reactive give any indication that the HSV-2 test could appear more accurate?

I am sorry to hear that. Your result is falsely positive, you do not have syphilis. Syphilis blood testing is done as a two-step procedure in which one test is done and, if positive, a second test is then performed to verify the results and avoid falsely informing people that they have Syphilis. When the first test is positive and the second test is negative the result is false positive and that person does not have Syphilis. That is your situation.  

FYI, Terri and the rest of us not uncommonly recommend similar 2-step testing in persons who have herpes blood test results that do not match up with the clinical situation. In that situation, we typically recommend the western blot test performed at the University of Washington for verification of initial positive herpes blood test results. This two-step testing procedure is not is widespread for herpes blood testing as it is for Syphilis.

Falsely positive RPR tests occur slightly more commonly in persons who have activated immune systems. This sort of activation may occur as the result of illnesses like rheumatoid arthritis or recently acquired viral or bacterial infections of any sort, however, in most persons with falsely positive RPR tests there is no specific association.  Your falsely positive RPR test does not mean that you have HSV.

Admittedly this is complex. If there is further clarification, please let me know in your final follow up question. EWH

Thank you for that insight.

My last question is in regards to supplemental testing for HSV-2. In my test on June 17, 2021 (index 2.43) and my most recent test, not mentioned before because I did not have the results, taken July 28, 2021 (index 2.33) the supplemental test was negative. All other tests did not show to have supplemental tests. Both tests are from LabCorp.

Is supplemental testing just repeating the previous test again? Also, if the supplemental test and the initial test show conflicting results how should the provider proceed? In the lab work itself, it says "Unable to confirm the presence of IgG antibodies to HSV-2." If that is the case,  and supplemental and initial tests are conflicting why is my provider insisting that HSV-2 is definitive? Does a conflict between the two tests further suggest false positives?

My WB test has been shipped and I anticipate clarification soon.

Thanks for your help.

Thanks for the additional information.  I'm afraid that I cannot clarify what the basis or performance characteristics of the LabCorp supplemental test.  In response to a recent change in the DCD's Guidelines for testing which were released earlier this month, supplemental testing has been recommended for persons in whom initial HSV results yield a low positive result as yours did.  This supplemental testing is meant to perform in the same way that the supplemental, 2nd test is used as described above for syphilis and it intended to reduce the numbers of falsely positive herpes blood test results.  Hopefully it will.  I would tentatively predict that your negative supplemental test is indicative that your initial blood test was falsely positive.  I suspect your University of Washington Western Blot will confirm that to be the case for you, i.e. that your blood tests were falsely positive.  

Rather than closing this thread at this time, I will keep it open for a while in the hope that you will post your Western Blot results.  EWH
