Hair testing is now recognized as a strong method for detecting drug and alcohol use. Hair offers a historical record of alcohol and drug usage by embedding biomarkers within the strands of growing hair. Collected near the scalp, hair can reveal approximately a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch section composed of roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, the ideal sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a recommendation of 150mg of the sample is suggested. Utilizing a jeweler’s scale for weighing the specimen is advisable. Should scalp hair be inaccessible, a comparable quantity of body hair may be utilized. The term head hair specifically refers to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory’s framework. This involves confirming the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data requirements not captured by an electronic chain of custody system.
Screening provides a preliminary rapid assessment for drug abuse. While Screening offers an economical method to exclude drug usage in most samples, positive screens require confirmation to be legally acceptable. Samples that are presumably positive in Screening necessitate additional confirmation.
Should a sample prove presumptively positive during Screening, more hair is extracted from the original specimen and processed for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), defining hair drug screening as a particularly challenging methodology.
Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples undergo necessary washing. The complete laboratory procedure from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
