How do blood and urine results differ?
Blood reflects short-term exposure while urine shows excretion over recent days. Doctors choose based on your exposure timeline.
How should I prepare for Arsenic (As) in Blood (EDTA)?
No fasting required, but avoid seafood for 48-72 hours before testing, as organic arsenic in seafood interferes with results.
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.
