Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a long-term insight into alcohol and drug use by capturing biomarkers in the fibers of the hair as it grows. When sampled near the scalp, hair can provide a detection period of up to roughly three months for alcohol and drugs. Hair is easy to obtain, challenging to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is advised. It's recommended to measure the sample on a jeweler's scale. Should scalp hair not be available, a similar amount of body hair might be taken. The term head hair refers specifically to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The core stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample into a lab's system. This incorporates ensuring the sample was sealed and dispatched correctly, generating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input not included by an electronic chain of custody system.
Screening constitutes a primary rapid assessment for drug abuse. Although Screening is a cost-efficient method to exclude drug usage in most samples, a positive result necessitates confirmation to be valid in legal settings. Any samples indicating a presumptive positive in Screening mandate a secondary confirmation.
For any sample showing presumptive positivity in the Screening phase, additional hair is retrieved from the original specimen, prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other approaches (e.g., urine or oral fluid), which makes hair drug screening notably challenging.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive specimens are cleansed before confirmation when necessary. The comprehensive laboratory procedure from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
