Hair analysis is regarded as a potent means for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and other drugs by embedding biomarkers in the strands as they grow. When clipped near the scalp, hair can reveal up to a 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to gather, relatively hard to tamper with, and convenient to ship.
Securing a 1.5-inch section of roughly 200 hair strands (approximating a #2 pencil thickness) nearest to the head will yield 100mg of hair, a perfect quantity for screening and verification. For EtG, additional tests, or those exceeding 10 panels, it's advised to obtain 150mg of the sample. We recommend measuring the sample using a jeweler’s scale. If head hair is not present, a similar amount of body hair may be used. When we mention head hair, we're specifically referring to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary steps in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample into the lab's system. It involves verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not provided through an electronic chain of custody system.
Screening provides an initial screening for drugs of abuse. While Screening is cost-effective for ruling out drug usage in most samples, a positive result requires verification to be acceptable in court. Any samples considered positive in Screening necessitate secondary confirmation.
When a sample shows presumptive positivity during Screening, additional hair is taken from the initial sample set and prepared for Extraction. In this stage, drugs are extracted from hair at far lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to conduct.
Positive results from screening are verified via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often called "hair follicle tests", the analysis is on the hair strand and not the follicle beneath the scalp.
