Hair analysis has gained recognition as an effective means for identifying substance and alcohol consumption. Hair offers a comprehensive record of alcohol and drug use by capturing biomarkers within the strands of the growing hair. When obtained near the scalp, hair can reveal up to a three-month window of detection for alcohol and drugs. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.
A sample measuring 1.5 inches, consisting of approximately 200 strands of hair (resembling a #2 pencil in size) nearest to the scalp, provides 100mg of hair, which is ideal for testing and confirmation. For EtG, extended panels, and/or tests that exceed 10 panels, a specimen of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair may be used. 'Head hair' refers solely to scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a specimen into a lab's system, which includes ensuring proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry when not supplied by an electronic chain of custody system.
Screening is a preliminary rapid assessment for substances of abuse. While Screening is an economical method to exclude drug usage in most samples, a positive screen must be verified before being permissible in legal proceedings. Presumptively positive samples in Screening necessitate further confirmation.
When a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. At this point, substances are isolated from hair at significantly lower concentrations than in alternative methods (such as urine or oral fluid), contributing to the complexity of conducting hair drug testing.
Validation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation if necessary. The comprehensive laboratory workflow from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis examines the hair strand and not the follicle located beneath the scalp.
