Hair testing is collected at fewer sites than urine, costs more, and cannot be turned round in a day whatever a search result promises. Employers order it because the detection window runs to about ninety days rather than a few days, and that is a real advantage for pattern detection. This page covers where it is collected, what it costs, and what same-day claims actually mean.
Collection is narrower than urine
Not every collection site in a national network is set up for hair. The collector cuts a small sample close to the scalp, usually from several places, and has to take enough length for the required detection period, which is normally about an inch and a half. Where there is insufficient head hair, body hair may be used, and the detection characteristics differ. Because fewer sites do it, the practical constraint on hair testing is often geography rather than price, and it is worth checking coverage against where your people actually are before committing to a hair programme.
Same day is a claim about collection, not results
A site advertising same-day hair testing is offering a same-day appointment. The analysis itself cannot be same day: the specimen goes to a laboratory, is screened, and any non-negative is confirmed by mass spectrometry before Medical Review Officer review. Hair testing typically takes longer end to end than urine, not less, and an employer building a start date around a same-day promise has misread what is being offered. If speed is the requirement, urine or an instant point of collection screen is the right instrument.
What it costs and why
Hair testing is consistently more expensive than a urine panel, because the preparation and analysis are more involved. Like all panel testing it is bought from collection and laboratory networks rather than from the background screening providers in this record: of the twenty-five providers here, the five that publish a price publish it for record searches, and none publishes one for hair testing. Ask whether a quoted figure includes the collection, the confirmatory analysis and the Medical Review Officer review, because those three are itemised differently by different vendors.
Where it is the wrong test
Hair is not an authorised specimen for Department of Transportation testing, so it cannot satisfy a regulated requirement. It does not reliably detect use in the last few days, because hair takes time to grow out of the scalp, which makes it unsuitable for post-accident or reasonable suspicion testing where recent use is the question. And alcohol is not detected in the same way. For pre-employment pattern detection in unregulated roles it is a strong instrument; for almost everything else there is a better one.
Questions people ask about hair follicle drug test near me
Can I get a hair follicle test the same day?
You can often get a same-day appointment. The result cannot be same day, because the specimen goes to a laboratory for screening, then confirmation if non-negative, then Medical Review Officer review.
How much does a hair drug test cost?
More than a urine panel, and it is quoted per test by the collection and laboratory network rather than by a screening provider. Confirm whether collection, confirmation and MRO review are included in the figure.
Why do fewer sites offer hair collection?
It requires a collector trained in the specific procedure and a laboratory set up for hair analysis. Coverage rather than price is often the binding constraint on running a hair programme.
Can hair testing be used for DOT purposes?
No. Regulated testing specifies urine, with oral fluid authorised in defined circumstances. Hair is not an authorised specimen for it.
