Hello, I had a potential HIV exposure 85 days ago. Since around 75 days after exposure, I have been experiencing itching and irritation on my hands and feet. I took an HIV DUO test after 80 days, and it came back non reactive with a value of 0.82. I am very anxious because of the persistent itching. Can you please explain why my blood test is negative even though I am experiencing these symptoms?

A non reactive HIV Duo test after 80 days is highly reliable. Itching may be due to allergy or skin condition, not HIV. No further HIV testing needed. Consult a dermatologist if itching persists.

For the past 3 years, I have been experiencing itching during summer. I have consulted many doctors, but the problem has not been cured for long. I have tried homeopathic medicines and other treatments, but without lasting relief. I am attaching my test report and would like your feedback and advice.

I want to know about my Allergy Screening Test by IMMUNO-EIA. The results are IgE 172 KU/L, Nimesulide 1.30 U/L, and Cephalosporin 1.20 U/L. What is the meaning of these values shown in my report? What should I do to treat it?

I consulted a doctor for skin and dust allergy. He advised an IgE serum test. The result shows IgE serum level greater than 3000. Is this very serious?
