In recent years, hair follicle drug testing has become a favored method for conducting drug screenings. Many employers, courts, and Substance Abuse professionals opt for a hair drug test over the traditional urine test. Hair follicle tests are preferred for zero-tolerance policies by employers, courts, and for those on probation. The key advantage is its longer detection window, up to 90 days, observed during collection, and being nearly impossible to tamper with. However, urine tests remain more precise for drug use within the past 5 days.

Hair analysis is regarded as a robust mechanism for identifying the consumption of substances like drugs and alcohol. Hair can offer a long-term record of these substances by embedding biomarkers within the fiber composition of growing hair strands. When sourced near the scalp, hair can deliver a detection span of roughly up to three months for alcohol and various drugs. The collection process for hair is straightforward, relatively resistant to tampering, and facilitates easy transport.
A 1.5-inch portion consisting of about 200 hair strands (equivalent to the size of a #2 pencil), taken closest to the scalp, yields 100mg of hair, which constitutes the ideal quantity for both preliminary screening and subsequent confirmation. For EtG, supplemental tests, and tests beyond 10 panels, a sample size of 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. Should scalp hair be unobtainable, an equivalent quantity of body hair may be procured. When referencing head hair, it precisely denotes scalp hair. Body hair pertains to all other varieties of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab's system. This step verifies appropriate sealing and shipping of samples, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry tasks absent from an electronic chain of custody framework.
Screening comprises an immediate preliminary check for substance misuse. Although cost-effective for ruling out drugs in most samples, a positive screen requires validation for legal acceptability. Presumptive positives from Screening necessitate confirmatory testing.
If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial sample for the Extraction stage. Here, substances are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.
Confirmation of any positive screen is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positivity are cleansed as necessary. The collective laboratory journey from Accessioning through to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
