Using hair testing has emerged as an effective method for identifying the consumption of drugs and alcohol. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the hair fiber's structure as it grows. If collected near the scalp, hair can offer nearly a 90-day period for detecting alcohol and other substances. Collecting hair is straightforward, challenging to tamper with, and effortless to transport.
A 1.5-inch segment comprising around 200 strands of hair (similar in size to a #2 pencil) obtained nearest to the scalp will yield 100mg of hair, which is considered the best sample for examination and validation. For EtG, additional tests, and/or testing beyond 10 panels, a 150mg sample is suggested. It's advised to weigh the sample on a jeweler’s scale. In the absence of scalp hair, the equivalent volume of body hair can be gathered. Reference to head hair pertains specifically to scalp hair. Body hair includes all other hair categories (facial, underarm, etc.).
Process Overview
The laboratory handling of a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the primary processing of a sample into a laboratory's records. It ensures proper sealing and shipping of the sample, the assignment of a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not merged by an electronic chain of custody system.
Screening covers an initial rapid assessment for substances of abuse. Whereas Screening provides a cost-efficient method to dismiss drug consumption for most samples, a confirmed result is essential for legal proceedings. Samples indicated as presumptively positive during Screening must undergo supplemental confirmation.
If Screening results are presumptively positive, additional hair is extracted from the initial sample for Extraction preparation. In this phase, drugs are isolated from hair at a considerably lower concentration than other standards (e.g., urine or oral fluid), highlighting the complexity of performing hair drug screening.
Confirmation of any positive Screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumably positive are cleansed before proceeding to confirmation where necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation alongside the accreditation to ISO/IEC 17025 standards.
