After use, ketamine is usually detectable for about 1 to 3 days in urine and around a day in blood and saliva. In hair it can remain visible for months. A lab quantifies the value, which is more reliable than a test strip.
How long is ketamine detectable?
The times below are guide values. They vary per person and per use pattern.
| Matrix | Approximate window |
|---|---|
| Urine | ± 1 to 3 days |
| Blood | ± 1 day |
| Saliva | ± 1 to 2 days |
| Hair | up to ± 90 days |
What does it depend on?
Dose, frequency and your metabolism help determine how long ketamine stays measurable. More context on all substances is in the overview of how long drugs stay detectable. For a targeted test, a ketamine screening can determine the ketamine value.
