Hair analysis has gained recognition as a formidable method for identifying drug and alcohol consumption. Hair encapsulates an extended chronology of alcohol and substances by embedding biomarkers in the hair strand's growing fibers. When obtained near the scalp, hair offers a roughly 3-month window for detecting alcohol and substances. Collecting hair is straightforward, with difficulties in tampering, and is easily shippable.
A 1.5-inch length consisting of around 200 hairs (approximately equivalent to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for screening and verification. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advised. It's beneficial to use a jeweler’s scale to weigh the specimen. Should scalp hair be unavailable, a similar quantity of body hair can be used. References to head hair mean solely scalp hair, whereas body hair encompasses all other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the laboratory's database. This involves confirming that the sample was appropriately sealed and transported, attributing a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody system.
Screening provides an initial rapid assessment for drug abuse. Though it's an economical strategy to exclude drug use in most samples, a positive screening must be validated to hold up in court. Samples indicated as presumptively positive in Screening necessitate further confirmation.
Should a sample exhibit presumptive positivity during Screening, more hair from the initial sample is extracted for the next phase. In the Extraction phase, drugs are removed from hair at much lower concentrations compared to other methods (e.g., urine or oral fluids), which is why hair drug testing is considered the most challenging method to conduct.
Confirmation of any positive screening results is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as required. The overall laboratory procedure from Accessioning to Confirmation is scrutinized under the guidelines of the CAP (College of American Pathologists) Hair stipulation and the accreditation to ISO / IEC 17025 standards.
