Frequently Asked Questions
Why is urine arsenic test preferred over blood?
Urine reflects recent arsenic exposure over the past 24–48 hours and is the standard specimen for detecting ongoing or recent arsenic poisoning, as arsenic is rapidly cleared from blood and excreted renally.
Is fasting required for urine arsenic test?
No, fasting is not required. A random or 24-hour urine collection is acceptable as directed by the clinician.
Can eating seafood affect urine arsenic results?
Yes, seafood such as fish, shellfish, and seaweed contains organic arsenic compounds (arsenobetaine) that can temporarily elevate urine arsenic levels. Patients are advised to avoid seafood for 48–72 hours before collection for accurate interpretation.
What does a high urine arsenic level indicate?
Elevated levels suggest recent exposure through contaminated drinking water, occupational contact (mining, pesticide use, welding), or arsenic-containing medications. Chronic high levels may indicate arsenic poisoning affecting skin, nerves, and internal organs.
How is the sample collected?
A clean-catch midstream urine sample of approximately 25 mL is collected in a sterile container. For 24-hour collection, all urine passed over a full day is preserved and sent to the lab.
