Hair analysis has gained recognition as an effective means for identifying drug and alcohol usage. Hair strands capture a long-term record of alcohol and drug consumption by embedding biomarkers within the hair's structure as it grows. When hair is cut near the scalp, it can unveil a detection period of up to roughly three months for alcohol and other drugs. Collecting hair is straightforward, not easily tampered with, and simple to transport.
Collecting a 1.5-inch section comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG screenings, additional tests, or those exceeding 10 panels, it is advisable to gather 150mg of the sample. Utilizing a jeweler’s scale to weigh the sample is recommended. If no scalp hair is present, a comparable amount of body hair may be used. By head hair, we mean only the hair on the scalp. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a laboratory's framework. It entails confirming the sample's proper sealing and delivery, allocating a random LAN (Laboratory Accessioning Number), and finishing any necessary data input absent from an electronic chain of custody system.
Screening incorporates an initial rapid test for drugs of abuse. Though Screening is an economical method for excluding drug use in the majority of cases, positive results must be confirmed to be valid for legal proceedings. Samples that test presumptively positive during Screening need further confirmation.
For samples presumptively positive at the Screening phase, additional hair is taken from the original sample for Extraction. At this stage, drugs are extracted from the hair at significantly lower concentrations compared to other methodologies (like urine or oral fluid), making hair drug screening a challenging procedure to implement.
Confirmation testing for any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if necessary. The complete lab process from Accessioning through Confirmation is monitored under both the CAP (College of American Pathologists) Hair criteria and the accreditation according to ISO / IEC 17025 standards.
