Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. The hair encapsulates a chronic record of alcohol and illicit substances by retaining biomarkers within its fibers during growth. When obtained near the scalp, a hair sample can offer an approximate 3-month window of detection for alcohol and other drugs. Collecting hair is straightforward, challenging to tamper with, and simple to dispatch.
An ideal sampling amount is a 1.5-inch piece containing about 200 strands of hair (roughly the width of a #2 pencil) nearest to the scalp, yielding 100mg of hair for evaluation and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. We advocate using a jeweler’s scale for measuring the sample. In situations where scalp hair isn't present, a similar quantity of body hair can be utilized. References to head hair exclusively mean scalp hair. Body hair refers to all other types of hair (facial, axillary, etc.).
Process Overview
The core stages in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the first phase of incorporating a sample into a laboratory's database. This step involves ensuring the sample is hermetically sealed and transported as required, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody system.
Screening is an expeditious preliminary test for substances commonly abused. Though Screening is a cost-effective strategy to exclude drug consumption in most samples, an affirmative screen must be validated for legal admissibility. Samples that yield a presumptive positive in Screening necessitate a secondary confirmation.
If a sample returns presumptively positive during Screening, more hair is extracted from the initial sample and arranged for Extraction. At this juncture, drugs are extracted from the hair at lower concentrations than other techniques (e.g., urine or oral fluid), which makes hair drug testing the most complex technique to execute.
Validation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positives undergo necessary washing. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.
