After someone has been infected with the virus it can take about 2 weeks for HIV antigen to be detectable with current antigen tests, and more than 3 weeks to produce enough HIV antibodies to be detected by antibody tests.

Dr. Hema Suggests...

Take a Culture, Nocardia (Does Not Include Antibiotic Sensitivity) Test or Take a ALLERGY, HOUSE DUST MITE (DERMATOPHAGOIEDS FARINAE) Test
