Hair drug testing is now recognized as a robust method for detecting drug and alcohol consumption. Hair serves as a long-term record of substance use by capturing biomarkers within the strands of growing hair. When taken near the scalp, hair can offer a roughly three-month detection period for alcohol and various drugs. The collection process is straightforward, the chance of tampering is minimal, and shipping is convenient.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp, provides 100mg of hair, which is optimal for both screening and confirmation. For EtG and additional tests beyond 10 panels, 150mg of the hair specimen is advisable. We suggest utilizing a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent volume of body hair can be collected. When mentioning head hair, we refer specifically to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The main procedure for processing a drug test result encompasses four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within the laboratory’s framework. This step confirms the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not covered by an electronic chain of custody system.
Screening entails an initial swift assessment for drugs of abuse. Although Screening is cost-effective for ruling out drug use in most samples, a positive result must be validated for legal admissibility. Any samples that yield a presumptive positive during Screening require a secondary confirmation.
Should a sample test positive during the Screening phase, additional hair is drawn from the original sample and prepped for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which highlights the complexity of hair drug screening.
Confirmation of any positive result from screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleaned prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
