Hello,
Thank you for choosing DoctorSpring.
I understand that this could be tiring and frustrating time for you. I will try my best to help you out here.
There are few possibilities here.
Your wife's infection seem to be recent. By recent I mean possibly within last 5 months.
I would recommend a PCR Viral load test also for your wife. For confirmation and for treatment decision (along with other standard tests)
Now your HIV negative status could be due to two reasons :
1. You are not infected. Not every sexual relationship need to result in HIV in this scenario. The more frequent the contact, the higher the risk. So if you did not have frequent sex during this time there is high chance you are not infected.
2. You are in the window period. (Yet to turn positive.) This less likely.
I would recommend you to go for a repeat Combo testing after 1 month.
Hope this clarifies.
Feel free to ask followups
Thank you
