Causes of False Negative HIV Antibody Test

Nov 15, 2010

Hi Dr. Bob,

Before anything else, I just want to thank you for your awesome job in this website. You truly are a good man.

Anyway, I just want to clarify something. Last November 11, I had my one year mark HIV test which thankfully turned out non reactive. However, I just have a concern. For my HIV test, I availed of a well-known clinic's home blood extraction service. A medical technician went to my house in order to extract a blood sample from my arm. Everything she did seemed legit and all but I noticed that after extracting my blood, she just put the "capsule" of my blood sample in a pouch and not in a cooler? Could that have killed the antibodies and affected the result of my test? Thanks a lot in advance for your answer.

Response from Dr. Frascino


You really can't kill antibodies, because they were never alive. Antibodies are proteins made by the body's immune system in response to a particular stimulus such as HIV. These proteins circulate freely in the blood. There is no need to refrigerate an HIV-antibody blood test. So relax Max, your results were not at all compromised.

Dr. Bob
