Hair testing has emerged as an influential method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and other substances by securing biomarkers in the strands as they grow. When hair is taken from near the scalp, it can reveal drug and alcohol use up to roughly a 3-month period. Collecting hair is straightforward, tampering with it is somewhat hard, and it can be shipped with ease.
A 1.5-inch portion consisting of about 200 hair strands (equivalent to the size of a #2 pencil) taken closest to the scalp yields 100mg of hair, which is the prime sample size for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair not be available, an equal quantity of body hair is acceptable. By head hair, we mean only scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the sample's initial processing into a lab's system. This includes checking proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and completing any additional required data entry not covered by an electronic chain of custody system.
Screening entails a preliminary quick test for drugs of abuse. Screening is a cost-effective way to exclude drug use in most samples, but any positive screen needs confirmation to be court-admissible. Samples that are presumptively positive during Screening require further confirmation.
If a sample is presumptively positive in the Screening phase, additional hair is extracted from the initial specimen to prepare for Extraction. During this phase, drugs are removed from the hair at concentrations lower than those used in other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of positive screening results is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The full laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 criteria.
