In recent years, the approach to drug screening has increasingly incorporated hair follicle drug tests. Many employers, courts, and substance abuse professionals now prefer hair drug tests over traditional urine tests. Employers with zero-tolerance policies, judicial entities, and individuals on probation utilize these tests for their extended detection window of up to 90 days, the observed collection process, and their resistance to tampering. However, for detecting very recent drug use within the past five days, urine tests remain the most precise option.

Hair analysis is now widely regarded as an effective method for detecting substance usage, including drugs and alcohol. By capturing biomarkers within the fibers of the hair as it grows, hair offers an extended timeline of alcohol and drug history. When hair is clipped near the scalp, it can reveal up to a 3-month period for drug and alcohol detection. Hair is straightforward to gather, moderately resistant to tampering, and uncomplicated to transport.
A 1.5-inch hair segment consisting of around 200 strands (roughly akin to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of hair specimen is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a similar volume of body hair can be retrieved. Note that when we refer to head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory’s system. This phase includes verifying the sample's integrity in terms of sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and carrying out any additional data entry absent from an electronic chain of custody mechanism.
Screening constitutes an introductory rapid assessment for illicit substances. Despite being cost-effective for excluding drug use in most samples, a positive screen must face confirmation to be legally accepted. All samples that appear positive during Screening necessitate further confirmation testing.
In instances where Screening yields a presumptive positive outcome, additional hair is taken from the original sample for the Extraction stage. In this phase, drugs are isolated from hair at concentrations considerably lower compared to other methods (such as urine or oral fluid), which explains the complexity of hair drug screening.
Confirmation for any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples that tested presumptively positive are cleansed if required. The lab process from Accessioning to Confirmation undergoes thorough review in alignment with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
