Hair analysis is recognized as an extremely effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug intake by embedding biomarkers within its growing strands. When harvested from near the scalp, hair can offer a detection timeline of up to three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.
A 1.5-inch section of roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp yields about 100mg, which is the optimal amount for both screening and validation. For extended testing such as EtG or over 10-panel tests, it is advisable to obtain 150mg. Measuring on a jeweler’s scale is recommended. If head hair is not present, a comparable amount of body hair is permissible. 'Head hair' specifically denotes scalp hair, whereas 'body hair' encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory method for processing drug test outcomes encompasses four central actions: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial step of integrating a specimen into the lab's system. This includes confirming proper sealing and transport, issuing a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic custody system.
Screening performs an initial sweep for drug traces. While economical, screening primarily serves to exclude drug presence in most samples; a positive finding in screening mandates confirmation to meet legal standards. Any samples provisionally positive must undergo an additional validation step.
Should a sample register as provisionally positive at the Screening phase, supplementary hair is harvested from the initial set for Extraction, concentrating on a significantly lower substance concentration compared to methods like urine or saliva testing. This renders hair testing more challenging.
Confirmation of suspect screening results utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed before necessary verifications. From Accessioning to Confirmation, this thorough lab procedure abides by stringent CAP (College of American Pathologists) Hair standards and conforms to ISO / IEC 17025 accreditations.
