Hair testing has increasingly gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug use by embedding biomarkers within the fibers of the hair shaft as it grows. When taken from near the scalp, this method can offer a detection period of up to roughly three months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient for transportation.
A hair sample of about 200 strands (approximately the width of a #2 pencil) cut closest to the scalp provides 100mg, which is the optimal amount for initial testing and confirmation. For EtG, additional requirements, and tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, an equivalent quantity of body hair might be used. References to head hair imply only scalp hair, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory process for testing drug presence encompasses four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the procedure of introducing the sample into the laboratory's framework. It entails verifying proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening provides a preliminary, rapid assessment for substances of abuse. While it is economically efficient in discounting drug use in most samples, the findings from a positive screen must undergo confirmation to be valid in a legal setting. Samples showing presumptive positives in Screening necessitate confirmatory testing.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample for further processing in the Extraction phase. In this stage, drugs are retrieved from hair at significantly lower concentrations than in other testing methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmation of any screening positives employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all presumptive positive samples are washed as required. The comprehensive laboratory procedure from Accessioning through Confirmation is subject to review under both the CAP (College of American Pathologists) Hair guidelines and accreditation according to ISO/IEC 17025 standards.
