Hair testing is increasingly valued for identifying drug and alcohol consumption. Hair captures enduring evidence of alcohol and drug use by embedding indicators within the hair fiber as it grows. Collected near the scalp, hair offers a detection timeline of up to about three months for alcohol and various drugs. It's easy to gather, challenging to tamper with, and straightforward to send.
An ideal sample for screening and confirmation involves a 1.5-inch segment of around 200 hair strands (approximately the size of a #2 pencil) from close to the scalp, yielding 100mg of hair. For tests such as EtG, add-ons, and/or panels exceeding 10, a sample of 150mg is advised. We suggest using a jeweler’s scale for measuring the specimen. If scalp hair is not available, equivalent body hair may be used. "Head hair" refers specifically to scalp hair only, while "body hair" encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The four principal phases in laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample in a laboratory system. This step involves confirming that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry missing from an electronic chain of custody system.
Screening entails conducting an initial expedited check for substance abuse. Although Screening provides an economical method for eliminating drug usage on the majority of specimens, the validity of a positive screen must be confirmed for legal proceedings. Samples indicating a presumptive positive in Screening thus need secondary verification.
In cases where a sample returns a presumptive positive during Screening, additional hair is taken from the original sample and prepped for Extraction. Here, drugs are isolated from hair in substantially lower concentrations compared to other methodologies (e.g., urine or saliva), highlighting the challenge of performing hair drug screening.
Verification of any positive screen outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation as necessary. The procedural chain from Accessioning to Confirmation is comprehensively audited under both the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.
