Which drug test fits you depends on the time window you want to cover. Urine is the most used and shows use over the past few days. Saliva mainly shows very recent use. Hair looks back furthest, up to around three months. A lab quantifies a value per substance, instead of a yes/no line.
Below I set the matrices side by side, so you can choose the test that fits your question.
Urine, saliva or hair test: what is the difference?
The matrix determines the detection window. Each type has its strength.
| Type | Window | Strength |
|---|---|---|
| Urine test | ± 1 to a few days | Widely used, good balance |
| Saliva test | ± 1 to 2 days | Recent use, simple to collect |
| Hair test | up to ± 90 days | Long look back, pattern over months |
Why a lab instead of a home test?
A home test gives a yes/no signal with a wide margin of error. A lab quantifies a value per substance with a reference range and a cut-off. In a borderline case, that can make the difference between doubt and a result you can support. Read more about home test versus lab test, about cut-off values and about false positive results.
Which substances stay detectable and for how long, you can read in how long drugs stay detectable. You can put together an extended 10-panel yourself or choose a single substance.
Every test result at Zuivertest includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
