Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair stores a prolonged record of alcohol and drug use through capturing biomarkers within its growing strands. When taken from near the scalp, hair can offer nearly a three-month window for detecting alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.
A sample of 1.5 inches, consisting of roughly 200 hairs (similar to a #2 pencil's thickness), taken nearest the scalp, yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is suggested. We propose weighing the specimen with a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
The fundamental steps in processing a drug test outcome in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample in a lab system. This step ensures the sample is correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry missing from an electronic chain of custody system.
Screening is a preliminary quick assessment for drug traces. While Screening is a cost-effective method to mostly eliminate drug consumption suspicion in samples, a positive result here needs validation for legal admissibility. Samples flagged as presumptively positive during Screening must undergo secondary confirmation.
If a sample is flagged presumptive positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening the most complex methodology to execute.
Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptive positives are washed before undergoing confirmation as necessary. The complete lab process from Accessioning to Confirmation follows scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
