Seen as a potent method for identifying drug and alcohol use, hair testing offers an extended overview by embedding biomarkers within the strands during hair growth. When obtained near the scalp, the hair provides a detection period of about three months for alcohol and drugs. Its collection is straightforward, somewhat tamper-resistant, and convenient for transportation.
A 1.5-inch hair specimen, roughly 200 strands (approximately the size of a #2 pencil) nearest to the scalp, yields 100mg of hair, optimal for both screening and confirmation. For EtG, extra panels, and tests exceeding 10 panels, a specimen weighing 150mg is advisable. Using a jeweler’s scale for weighing is recommended. In cases where scalp hair is not available, a comparable quantity of body hair can be used. By head hair, we mean scalp hair exclusively, while body hair pertains to all other kinds (facial, axillary, etc.).
Process Overview
The key stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, samples are initially integrated into the lab’s system. This step includes checking the sample's seal and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.
Screening constitutes an initial, swift evaluation for drug abuse. Though cost-effective for eliminating drug use in most samples, positive screen results require confirmation to stand in legal settings. Any samples with presumptive positive results in Screening need further verification.
If a sample shows presumptive positivity in Screening, more hair is sourced from the specimen and made ready for Extraction. This stage extracts drugs from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), hence making hair drug screening the most challenging methodology to carry out.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned prior to confirmation as needed. From Accessioning to Confirmation, the whole laboratory process is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.
