Hair testing is regarded as a formidable means for detecting alcohol and drug use. Hair captures a comprehensive timeline of substance consumption by embedding biomarkers within the fibers of the maturing hair strand. When obtained near the scalp, it offers an approximate 3-month timeframe for identifying alcohol and drug presence. Collecting hair is straightforward, hard to tamper with, and simple to transport.
A sample of 1.5 inches consisting of roughly 200 strands close to the scalp provides 100mg, which is optimal for examination and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't present, a comparable amount of body hair can be sourced. References to head hair signify scalp hair solely, whereas body hair pertains to other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary processing of a sample into a lab's database. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not included by an electronic chain of custody.
Screening conducts an initial swift analysis for drugs of abuse. Although Screening serves as a cost-effective method to preclude substance use on many samples, confirmation is required for any screen to be admitted in court. Presumably positive samples in Screening mandate a secondary confirmation.
For presumptive positives in the Screening phase, more hair is extracted from the initial collection and readied for Extraction. In this phase, drugs are isolated from hair at a substantially lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug screening a challenging technique.
Confirmation of any positive screening outcome is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing pre-confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO / IEC 17025 standards.
