With hair testing gaining recognition as an effective method for identifying drug and alcohol consumption, it offers a way to capture a timeline of substance use. Hair embeds biomarkers within its growing strands, allowing for a detection span of up to three months when sourced near the scalp. The process of gathering hair is straightforward, challenging to falsify, and easy to transport.
Collecting a 1.5-inch lock of about 200 hair strands, roughly the thickness of a #2 pencil, from near the scalp yields 100mg of hair, which is the preferred amount for both screening and verification. For tests such as EtG, additional testing, or those exceeding 10 panels, it is advisable to have 150mg of the sample. Measuring the amount on a jeweler’s scale is suggested. If scalp hair isn’t available, a comparable quantity of body hair can be taken. 'Head hair' references are to scalp hair only, whereas 'body hair' encompasses all other hair types (e.g., facial, armpit).
Process Overview
The drug test processing in laboratories comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process where a sample is initially logged into a lab’s system. This step includes checking that the sample is properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and filling out any remaining data entry that an electronic chain of custody system does not cover.
Screening conducts a preliminary and quick assessment for the presence of drugs. While cost-effective for discounting drug use in most samples, a positive result here needs validation for it to be court-worthy. Samples flagged as likely positive during Screening require further confirmation.
Should a sample yield a likely positive result in Screening, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are separated from hair in lower concentrations than other methods (e.g., urine or saliva), rendering hair drug testing one of the hardest methodologies to execute.
The validation of any initial positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are pre-washed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair guidelines and meets the accreditation criteria of ISO / IEC 17025 standards.
