Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a chronicling medium for alcohol and drug use by encasing biomarkers within the fibers of the maturing hair shaft. When sampled near the scalp, hair can offer an approximate three-month detection period for detecting alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and convenient for transportation.
A collected section of hair measuring 1.5 inches, approximately 200 strands in volume (comparable to a #2 pencil's girth) near the scalp, results in 100mg of hair, which is optimal for both examination and affirmation. For EtG, additional assessments, or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to measure the sample weight using a jeweler’s scale. If no scalp hair is available, an equivalent quantity of body hair can be gathered. Head hair specifically denotes scalp hair, whereas body hair encompasses other hair types (such as facial, axillary, etc.).
Process Overview
The core procedures in processing a drug testing outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake of a sample into the laboratory system. It entails confirming proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not captured by an electronic chain of custody system.
Screening is an introductory evaluation for substances of abuse. While Screening provides a cost-effective means to rule out drug use in most samples, a positive result necessitates further validation for legal admissibility. Samples presumed positive during Screening require additional confirmation.
Should a sample be presumptively positive during Screening, extra hair is extracted from the initial sample for preparation in Extraction. In the Extraction stage, drugs are isolated from hair at a much lower concentration than other methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is among the most elaborate testing methodologies.
Any positive Screening finding is verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive undergo washing before confirmation, as necessary. The entire lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
