Hello, Welcome to icliniq.com.
The test kits used these days to diagnose HIV (human immunodeficiency virus) are highly sensitive and specific and gives accurate results. Your negative HIV test results (attachments removed to protect the patient's identity) at six and then at ten months of exposure are accurate. I am quite sure you are HIV negative. Kaposi sarcoma which you are referring to is a very late manifestation of HIV and is seen in patients with advanced immunosuppression and also usually found in homosexual HIV-infected individuals. You are HIV negative. If the lesion persists on the nose, kindly show it to a dermatologist or an ENT (ear, nose, and throat) specialist for a correct diagnosis. Hope your query is answered, but please do not hesitate to ask or call anytime for any further query.
