I had an exposure on 2/11/2025

It was unprotected oral

A skin rash started to appear on 15/11/2025

Waited for 8-10 weeks

After 67 days (9/01/2026) I performed the following :

HIV P24 Antigen and antibodies : Negative

Hepatitis B : Negative

Hepatitis C : Negative

Syphilis : Negative

But the problem that the lab was performing Syphilis Test as Rapid Test (chromatographic immunoassay) which is similar to the rapid one online.

The rash only started to fade late on February , but still some of the small stains are around , above arms , Trunk and upper legs.

Still having some symptoms appearing and going away.

The question now is :

HOW MUCH THIS LAB RAPID TEST CAN BE SENSETIVE AND NOT GIVING A FALSE NEGATIVE????

Appreciate your help please 🙏🏼
