[Question #2936] 4th Generation HIV Test @ 16 day after Exposure
92 months ago
|
Hi Doc,
My wife of 19 years was recently diagnosed with HIV after blood splash incident at work with one of her patient. Am I at risk to have performed vaginal oral sex on her (brushed my teeth 30mn before)? The reported viral load was around 10000 couple of days after the oral sex. I tested 16 days after the exposure with 4th generation Ab/Ag with LabCorp that came back negative? Is that reliable? Should I expect a similar result @ 16 weeks. Just tested this morning and waiting for the next result. Extremely anxious with shooting pain in neck/shoulder over 3 month followed by arm and leg pain & tingling. I've also noticed small white spot on my skin (underarm and stomach) but not sure it they've always been there since I never paid attention to until recently.
Please help me understand the risk. I've not being felling well the past 12 weeks - no fever, sore throat and etc... just general Gerd and anxiety issues.
Thanks,
MM

Thanks for the reassurance doc! The 4th generation test @ 16 weeks came in today and was non-reactive as you had said in your email. I can now focus on my wife and our kids.
As for my wife’s situation, thanks for the kind words. This is a very unusual situation and we have tried repeatedly to understand the source of the infection along with the hospital infectious disease doctor who initially reassured us this was a false positive giving the risk of the exposure and our life style. Unfortunately, after several round of testing and it was confirmed that in fact it is a true positive. To make matter worse, his analysis speculates that the nature of the infection could not have been from that exposure and as a result the patient (source) was never contacted and tested for HIV by the hospital and Workers comp was denied which we’re trying to get our lawyer to appeal.
She is currently under the care of Margaret Fischl team @ UM HIV/Aids research and was put on HAART immediately. Her viral load is now undetectable within 3 weeks and the expectation is that she would be OK...Praising the Lord. However, they do believe this is a recent infection due the CD4/CD8 ratio and viral load fluctuation prior to her starting HAART. Also she repeatedly tested negative in the past and breastfed our child thru Sept 2016 who recently tested negative by UM pediatric team (worse 4 day wait of our life).
The incident with my wife occurred on June 13th and while she was pulling an IV out of one of her patient, she felt a drop in her eye (saliva or blood not sure) and quickly ran to the nurse post station to wash it out but didn’t notice any blood. She also checked the patient chart and didn’t see anything unusual, therefore never reported the incident. A week later she had an unusual sinus and eye pressure and was prescribed some antibiotics but never developed any fever or any other symptoms but claimed she wasn’t feeling herself. She later told me about the incident and with the lingering sinus and eye pressure, I immediately urged her to report it to employee health which she did the next day on July 12th. She was tested for several STDs and HIV came back reactive. Besides this incident, the only exposure she could have had was a dental procedure done while she was still breastfeeding and a pap smear and routine dental cleaning done early this year. The Pap smear did reveal she was with and was prescribed Mifeprex per our request. She later had a cold with mouth sores around March and also had two episodes of yeast infection. I myself routinely tested negative for HIV back in Feb due to low WBC count which I’ve never done in almost 20 years. We’re still unable to get our mind around this whole situation.
This is extremely hard on us and we’re taking it one day at a time with a lot of gilt as to what we could have done differently. Sometime we do ask ourselves if this is real as she had false positive RPR in the past while pregnant. However, we’re working with good doctors and strongly hope every will be OK.
Do I need any further testing at this point post 16 weeks? The doctor told me I should test twice a year, any thoughts… How about the kids? Should they be tested occasionally as well? Please advise.

Thank you for the feedback Dr.! You and Dr. Hook are doing an amazing job and can’t imagine how many life you’re impacting. Truly appreciated…
My apologies but the reason I didn’t mention any sexual or drug injection risk is that there are non-existent. My wife and I have been in a 100% committed relationship for almost 19 years, no alcohol, cigarette, drug or any substance abuse. Any sexual risk (if there’s any with protected sex) would have been from me 20 years ago before we started dating and I’m the only guy she has ever been with. There’s absolutely no doubt in my mind how faithful we’re to each other and that’s what makes this situation so difficult to digest. Now that I can remember we both tested negative for all STDs including HIV and substance abuse back in 2013 for our life insurance application.
As far as other risks if there are in fact potential risks for HIV transmission would have been surgeries – I had 4 surgeries in the last 15 years - 2 endoscopy, 1 colonoscopy and a dental surgery late 2015. As for my wife, she had 2 surgeries - a C-section and then an episiotomy in 2015.
The UM team focus is usually on the patient and their advise to me was to get tested 28 day post exposure with the 4th Gen ag/ab to confirm I’m negative. Per my wife’s doctor occupational exposure is rare but real and for that reason they always advise people to report every incident as soon as possible no matter the type of exposure.
I did talk to my family doctor about the RNA/DNA test and he believes my anxiety is getting the best of me that I should maybe consider therapy. He’s saying that at 17 weeks, the 4th Gen ag/ab test is conclusive per the CDC guideline and the RNA/DNA is typically use to confirm any undeterminate 4th Gen. He believes that I’m hypochondriac as early this year, against both he and the GI advise regarding my low WBC which has been the same for almost 13 years (which both of them always believe is normal), I saw a hematologist who ordered several test including HIV back in February of this year to rule out any stomach cancer which has always being my concern due to previous H pylori infection back in 2002 and chronic gastritis.
CBC, SMA-7, and LFTs
Vitamin B12 and folic acid level
Serum protein electrophoresis and serum immunofixation
Thyroid profile
ANA and rheumatoid factor
HIV screen
Viral hepatitis profile
Flow cytometry
Now I’m thinking I could have been infected thru one of these procedures I’ve done in the past and then gave my wife this disease. Is realistic for the 4th gen to be false negative after all these years if in fact I’m positive? My PCP thinks I’m being irrational and did give me a script for both 4th gen ag/ab and PCR RNA to be done next January 2018 with the instruction that the PCR RNA is to be done only if the 4th Gen is reactive. He also thinks the results to my unnecessary test above are best indicator that I’m not HIV positive and I didn’t unknowingly infect my wife. My wife situation, although rare is unfortunate and could have been from anything (cut, needle, blood splash, etc.…) giving the fact she works in a hospital setting. I keep thinking we’re living a nightmare. Can the RNA/DNA yield a positive result 5-6 months post-exposure giving the fact that the 4th Gen is negative? Isn’t the 4th gen conclusive at 28 days? I’m a ball of nerve right now and can’t stop thinking about the possibility of both of us having the disease. I’m scared for our kids.
So far I tested 3 times. What the chances that still could turn positive? Please help
07/28 - Day 16 Rapid antibody Test - Negative
07/08 - Day 16 4th Gen Ab/ag Labcorp - Negative
11/07 - 17 Weeks 4th Gen ab/ag QuestLabs - Negative
