Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair offers a prolonged record of substance use by embedding biomarkers within the strands of the hair as it grows. When collected near the scalp, hair can reveal substance use within an approximate 90-day detection window. Hair samples are easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch sample of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional tests, and/or testing exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair may be used. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the sample's initial entry into the laboratory’s system. This step involves ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input missing from an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drug usage. Although Screening is cost-efficient for eliminating the possibility of drug presence in most samples, any positive result requires confirmation for legal admissibility. Samples showing presumptive positivity in Screening mandate further confirmation.
If Screening suggests a positive result, the original sample's additional hair is utilized for Extraction. Here, drugs are extracted at a lower concentration than other methods (e.g., urine or oral fluid), making hair drug testing the most complex methodology to execute.
Confirmation of a positive Screening result is conducted using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation, as required. The entire lab process, from Accessioning to Confirmation, is subjected to scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
