Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair offers a prolonged history of substance use by capturing biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair samples can provide nearly a 3-month detection period for substances. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch sample of roughly 200 hair strands (similar to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample size for screening and confirmation. For EtG, extra tests, and/or panels above 10, a 150mg sample is suggested. It is advisable to weigh the sample on a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair can be gathered. References to head hair specifically denote scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four key phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab’s system. This process involves confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.
Screening constitutes a preliminary rapid assessment for substances of abuse. While Screening serves as a cost-effective method to exclude drug use in most samples, a positive screen is necessary for court admissibility and thus requires confirmation. Samples that are initially positive in Screening necessitate a subsequent confirmation.
In cases where the Screening stage suggests positivity, more hair is used from the initial sample to prepare for Extraction. Drugs are extracted from hair at a significantly lower concentration compared to other methodologies (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.
Confirmation of any positive screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
