What this test is
The test measures benzene in blood. Benzene is carcinogenic and suppresses blood cell production, so continuous exposure lowers white cells and platelets and raises the risk of leukaemia.

Frequently asked questions about this test
Why sample at the end of a shift?
Benzene clears from the body quickly, so end-of-shift sampling best reflects that day's exposure.
How does benzene affect blood?
It suppresses bone marrow blood cell production, causing anaemia, infections or bleeding at high continuous exposure, so CBC monitoring is used alongside.
How should I prepare for Benzene in Blood (NaF)?
No fasting required. Avoid smoking beforehand and describe work involving fuel or solvent vapour.
How long do results take?
About 15 days, depending on the laboratory workload that day. Our staff will confirm the collection time when you are served.
Where can I have this test done?
Samples are collected and results issued at S.F. Laboratory, the in-house laboratory of BK5 Med Health Clinic in Don Hua Lo, Chon Buri. No appointment is needed; walk in during opening hours.
