Recently, the use of hair follicle drug testing has become more common in drug screening methods. Employers, judicial systems, and Substance Abuse counselors often prefer hair tests over traditional urine screens. This method is favored by employers with strict anti-drug policies, courts, and probation programs. Hair follicle tests boast an extended detection window of up to 90 days, require observed collections, and are nearly immune to tampering. Nonetheless, for detecting recent drug use within five days, urine tests remain the preferred method.

Hair testing has emerged as a robust resource for identifying drug and alcohol usage. Hair retains a lengthy record of alcohol and other substances by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can reveal usage within an estimated 3-month span for alcohol and other drugs. Hair sampling is straightforward, resistant to tampering, and convenient for transport.
A sample measuring 1.5 inches, comprising around 200 hair strands (similar in size to a #2 pencil) near the scalp, supplies 100mg of hair, an optimal quantity for both screening and verification purposes. For EtG enhancements, or evaluations exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair is an alternative. Regarding head hair, we specifically refer to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a lab’s system. This step involves confirming the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.
Screening involves an introductory rapid assessment for drug misuse. Although Screening presents a cost-efficient method to eliminate drug usage in the majority of samples, a positive screen must undergo confirmation to hold up in court. Samples that appear presumptively positive during Screening require an additional confirmation.
If a sample is deemed presumptively positive during the Screening phase, further hair is extracted from the initial sample for the Extraction stage. In this phase, substances are isolated from hair at a much reduced concentration compared to other methods (e.g., urine or oral fluid), contributing to hair drug screening being the most elaborate method to execute.
Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples showing presumptive positives are cleaned before confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes inspection under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standard accreditation.
