Hair assessments have emerged as a significant means for identifying the usage of drugs and alcohol. Hair serves as a repository for a prolonged timeline of substance use by capturing biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can offer a detection window of roughly three months for alcohol and various drugs. Hair is convenient to gather, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp provides a 100mg hair sample, which is the optimal amount for screening and validation. For EtG and additional tests extending beyond 10 panels, a 150mg specimen is advised. We suggest weighing the specimen using a jeweler's scale. If scalp hair is unobtainable, an equivalent volume of body hair may be gathered. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory process in analyzing a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial handling of a sample upon its entry into a laboratory's system. This step includes confirming the sample was adequately sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and performing any additional data input absent from an electronic chain of custody.
Screening provides an initial swift assessment for substances of abuse. While Screening serves as an economical method to dismiss drug usage in many samples, any positive screen must be confirmed for legal acceptance. Samples yielding a presumptive positive during Screening necessitate secondary confirmation.
Should a sample show presumptive positivity in Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are removed from hair at reduced concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug assessment the most challenging technique to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that demonstrate presumptive positivity undergo a wash before confirmation as required. The complete laboratory procedure, from Accessioning through Confirmation, is scrutinized in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
