Choosing a Specimen Type
Each specimen type answers a different question about when a substance was used.
| Specimen | Typical Detection Window | Commonly Used For |
|---|---|---|
| Urine | Roughly 1 to 4 days for most substances, longer with frequent cannabis use | Pre-employment, DOT, random |
| Hair | Up to about 90 days | Pre-employment, custody matters, longer history |
| Saliva (oral fluid) | About 24 to 48 hours | Reasonable suspicion, post-incident |
| Nail | Typically longer than hair, varying with nail growth | Extended history, hair unavailable |
| Breath alcohol | Current impairment only | DOT alcohol testing, post-accident |
| Urine EtG (alcohol) | Up to about 80 hours | Court ordered abstinence monitoring |
Detection windows are approximate and depend on the substance, frequency of use, dose, and individual metabolism. Testing for a court, employer, or program? Confirm which test they require before you order.
