Hair analysis has emerged as an effective means for detecting the consumption of drugs and alcohol. By binding biomarkers within the strands of developing hair, it captures a prolonged historical record of alcohol and drug intake. Collected from close to the scalp, hair presents up to an approximate 3-month timeframe for identifying alcohol and drug presence. It is easy to collect, relatively resistant to tampering, and straightforward to transport.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (comparable to the diameter of a #2 pencil) nearest to the scalp, provides 100mg of hair, ideal for both screening and validation. For EtG enhancements, or evaluations exceeding 10 panels, 150mg of the hair specimen is advised. Utilizing a jeweler’s scale for specimen weighing is suggested. In cases where scalp hair is unobtainable, a similar quantity of body hair is permissible. References to head hair imply scalp hair exclusively, whereas body hair pertains to all other varieties (facial, axillary, etc.).
Process Overview
The process comprises four key stages in the lab analysis of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the preliminary incorporation of a sample into the lab's framework, encompassing sample sealing and shipping verification, assigning a unique LAN (Laboratory Accessioning Number), alongside completing necessary data entry absent from an electronic chain of custody.
Screening refers to an initial, swift evaluation for abuse substances. Despite Screening’s efficiency in dismissing drug usage for most samples, confirmation is essential for legal admissibility. Presumptive positives in Screening necessitate subsequent confirmation.
In cases of presumptive positivity in Screening, additional hair is extracted from the initial sample for Preparation during Extraction. Here, substances are isolated from hair at reduced concentrations compared to urine or oral fluid methods, contributing to the intricate nature of hair drug testing.
Verification of a positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo cleaning prior to confirmation as required. The complete process, from Accessioning to Confirmation, undergoes scrutiny under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
