Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a long-term record of alcohol and drug use. When taken close to the scalp, hair can offer a detection window of up to about 3 months for alcohol and drugs. Collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch hair sample, comprising roughly 200 strands (comparable to the size of a #2 pencil) near the scalp, yields about 100mg, which is ideal for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is preferred. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is not obtainable, an equivalent quantity of body hair can be utilized. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary incorporation of a sample into a lab’s system, ensuring its appropriate sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any auxiliary data entry absent in an electronic chain of custody system.
Screening serves as an initial rapid check for drug abuse. Despite being a cost-effective method to rule out drug usage in most samples, positive screens require confirmation for court admissibility. Samples presumptively positive in Screening necessitate secondary confirmation.
Should a sample indicate a presumptive positive in Screening, more hair is extracted from the original specimen and readied for Extraction. This phase involves drug extraction at significantly lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening particularly challenging.
Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Required presumptive positive samples are washed before confirmation. The entire process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
