Hair assays have gained recognition as an effective modality for identifying substance and alcohol consumption. Hair encapsulates a detailed history of substances, including alcohol, by embedding biomarkers within the hair fiber as it grows. When collected near the scalp, hair can offer a detection timeframe of nearly three months for substances. It is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A hair sample measuring 1.5 inches with roughly 200 strands (approximately the thickness of a #2 pencil) nearest the roots yields 100mg of hair, which is ideal for both screening and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's recommended to measure the sample using a jeweler's scale. If scalp hair is not accessible, a similar volume of body hair may be used. Referring to head hair pertains specifically to scalp hair, while body hair encompasses all other types (like facial or axillary hair).
Process Overview
The laboratory processing of a drug test result comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introductory processing of a sample within a lab’s framework. This stage involves validating the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not supplied by a digital chain of custody system.
Screening conducts an initial rapid assessment for drug misuse. Although Screening offers a cost-efficient method to exclude drug consumption for most samples, any positive screen must be verified for courtroom admissibility. Samples that result presumptively positive during Screening necessitate a subsequent confirmation.
Should a sample show presumptive positivity during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are removed from hair at notably lower concentrations compared to other techniques (such as urine or oral fluids), marking hair drug screening as the most challenging technique to execute.
Verification of a positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo cleansing as needed. The comprehensive laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
Benefits of hair drug assays:
Drawbacks:
Note: Although frequently called "hair follicle tests," the examination targets the hair shaft rather than the follicle beneath the scalp.
