Lately, the hair follicle drug test method has become more common in drug testing practices. Employers, courts, and Substance Abuse professionals are opting for hair tests instead of traditional urine tests. These tests are favored by employers with zero-tolerance policies, the courts, and probation systems for their longer detection period—up to 90 days—acquired through a supervised process, making them difficult to tamper with. However, urine tests remain accurate for detecting very recent drug use, within 5 days.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair testing is recognized as a robust method for detecting substance and alcohol use. Hair retains a historical record of alcohol and drugs by capturing biomarkers within the strands' fibers. A sample taken near the scalp can offer a detection period of up to three months for alcohol and various drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A sample measuring 1.5 inches from the scalp, containing approximately 200 hairs (around the thickness of a #2 pencil), yields 100mg, an optimal quantity for testing and verification. For EtG, add-ons, or panels exceeding 10, it is advisable to obtain 150mg of the sample. We suggest using a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent volume of body hair can be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The drug test laboratory procedure is comprised of four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial entry of a sample into the lab's system, which entails checking the sample's seal and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and completing data entry not covered by an electronic chain of custody.
Screening is a preliminary assessment for substance abuse. While cost-effective for excluding drug use in most cases, any positive screening must be corroborated for legal acceptability. Presumptive positive samples from Screening necessitate further verification.
If a sample tests presumptively positive during Screening, more hair is extracted from the initial sample for the Extraction stage. Here, drugs are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug screening is a complex methodology.
GC/MS, GC/MS/MS or LC/MS/MS techniques are employed to confirm any positive screening results. Presumptive positive samples undergo washing before confirmation as needed. Every stage from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
