In the past few years, hair follicle testing has increasingly become the preferred method for drug testing. Employers, judicial systems, and substance abuse counselors now often favor it over traditional urine tests. This test is especially vital for employers with strict no-drug policies, court mandates, or individuals under probation. The standout advantage of hair testing is its extended detection window, typically up to 90 days, while being secure from tampering. However, testing for usage within a five-day window continues to rely on urine tests for peak accuracy.

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged timeline of substances by embedding biomarkers within the strands as they grow. When harvested near the scalp, hair analysis can reveal alcohol or drug exposure within an approximately 90-day timeframe. Hair collection is straightforward, less prone to tampering, and convenient for transport.
A sample consisting of 1.5 inches of around 200 hair strands (roughly equivalent to a #2 pencil) from near the scalp yields 100mg of hair, which is optimal for testing and validation. For EtG, additional tests, and/or more extensive panels beyond 10 drugs, a sample size of 150mg is advised. Utilizing a jeweler’s scale for measuring the specimen is recommended. In scenarios where scalp hair is absent, an equal volume of body hair can be utilized. The term "head hair" refers specifically to scalp hair. Conversely, "body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug-testing sample is comprised of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, involving the integration of a sample into the laboratory's workflow. It encompasses ensuring proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any further data entry needs not covered by an electronic chain of custody system.
Screening is a preliminary, cost-efficient assessment to check for drug presence. While effective for excluding drug use in most samples, any positive result from Screening necessitates further confirmation to be considered valid in legal contexts. Any samples showing a presumptive positive in Screening require subsequent confirmation.
Should a sample show presumptively positive results during Screening, additional hair from the original sample is utilized for Extraction. During this phase, drugs are extracted from hair at notably lower concentrations than other methods (such as urine or oral fluid), thus making hair drug screening the most challenging to execute.
The Confirmation process for any presumptively positive Screening result is carried out using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo a washing process as necessary. The full laboratory workflow from Accessioning to Confirmation is assessed in accordance with the CAP (College of American Pathologists) Hair designation, and conforms to ISO / IEC 17025 accreditation standards.
