Hair follicle drug testing.
Hair testing analyzes the hair shaft, giving a detection window measured in months and harder adulteration than urine. JDP sells it with collection, lab, and MRO; it is not a DOT substitute.
Also called hair drug test, hair follicle drug screen.

What it covers
Lab-based hair analysis for the ordered panel, with MRO review- A detection window of roughly 90 days, depending on hair length and lab protocol
Candidates learn how long to abstain before a urine test; hair defeats that. The trade-offs are cost, collection logistics (enough hair), and the same state-law questions as any drug test.
What it covers
- Lab-based hair analysis for the ordered panel, with MRO review
- A detection window of roughly 90 days, depending on hair length and lab protocol
What it doesn’t cover
Replace a DOT urine test- Detect use last night — hair is the opposite of instant
- Work equally well on every hairstyle; collection has constraints
Where the data comes from.
Hair-testing labs via partner CRAs / TPAs
Collection plus laboratory analysis — not a clinic instant device.
Why identity comes first.
Identify the donor at collection. A long window is worthless if the sample belongs to a roommate.
How the network fulfills it.
Not every workplace-testing partner does hair well; the network includes ones that do. Site match still matters.
This is the wrong search if…
You needed a same-day pre-shift screen
Instant urine or oral fluid. Hair is not that.
DOT-covered and you wanted to skip urine
You cannot.
