Frequently Asked Questions

How accurate is saliva testing?

Saliva testing is highly accurate for detecting recent drug use. It has lower false positive rates than urine tests and is difficult to adulterate because collection is directly observed.

Can I eat or drink before a mouth swab test?

Avoid eating, drinking, smoking, or chewing gum for at least 10 minutes before the test. Food particles can interfere with sample collection.

How long does THC stay in saliva?

THC is typically detectable in saliva for 24-48 hours after last use. This is much shorter than urine detection, making saliva ideal for same-day or next-day testing.

Cost & Pricing

The Mouth Swab Drug Test typically costs between $39 and $79 when ordered directly through a certified lab. Prices may vary by location.
