Hi, i recently had a blood test taken for hepatitis b, c and HIV. I was wondering if from the blood test, a smoker can be detected. Maybe through nicotine levels and what not. If so, how long will it take for it to be removed from the system?

Hello, and thanks for your medical question on E Health Forum.

Blood tests done for screening for HIV, and hepatitis, do not detect your smoking status.

I hope this helps.
