Hair analysis is recognized as a formidable means for identifying drug and alcohol consumption. Hair locks in biomarkers within the fibers of the growing strand, offering a long-term history of substance use. When sampled near the scalp, hair can show a detection window of up to roughly three months for drugs and alcohol. The collection process is straightforward, the sample is somewhat hard to tamper with, and it's easy to transport.
A 1.5-inch segment of around 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp provides about 100mg of hair, which is the optimal sample for screening and validation. For EtG, additional testing, and/or panels beyond the basic 10, a 150mg sample is advisable. We recommend using a jeweler's scale to measure the sample. In cases where scalp hair is inaccessible, a comparable amount of body hair can be taken. The term head hair refers strictly to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory workflow for processing a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the introduction of a sample into the lab's system. This includes ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody protocol.
Screening offers a preliminary rapid assessment for substances. Screening is an economical method to eliminate drug use in most samples, but a positive result requires confirmation to be valid for legal purposes. Any samples that yield a presumptive positive in Screening necessitate further confirmation.
Should a sample test presumptive positive during Screening, additional hair is taken from the initial sample and readied for Extraction. In this phase, substances are retrieved from hair at much lower concentrations than in other methods (e.g., urine or saliva), which partly explains why hair screening challenges execution.
Confirmation for any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples presumptively positive undergo washing prior to confirmation, as necessary. The laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
