Hair testing is recognized as an effective technique for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands, hair offers a comprehensive timeline of substance usage. Proximity-based collection near the scalp can reveal alcohol and drug traces over a period of up to three months. The simplicity of collecting hair samples, their resistance to tampering, and ease of transport make this method highly practical.
For optimal screening and validation, a sample of 1.5 inches or roughly 200 hair strands (approximating the thickness of a #2 pencil) from near the scalp is required, yielding 100mg of hair. However, for EtG tests, add-ons, or tests beyond 10 panels, a 150mg sample is advised. It is suggested to measure the sample using a jeweler’s scale. In cases where scalp hair is not available, an equivalent mass of body hair can be used. Note that when we mention head hair, it specifically pertains to scalp hair, whereas body hair includes all other types (such as facial and axillary hair).
Process Overview
Laboratory drug testing processes involve four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a specimen into the lab's system. It includes verifying sample integrity, correctly assigning a LAN (Laboratory Accessioning Number), and completing any data entry absent from an electronic chain of custody system.
Screening consists of an initial examination for signs of drug abuse. While it's an economical method to eliminate drug usage in most samples, a positive result must be verified to be court-admissible. Samples with a presumptive positive result in Screening necessitate secondary verification.
In instances of presumptive positivity in Screening, additional hair is derived from the sample for Extraction. During this phase, drugs are extracted from the hair at concentrations considerably lower than those found in other samples (like urine or oral fluid), making hair drug screening the most challenging methodology to execute.
For positive screening results, GC/MS, GC/MS/MS, or LC/MS/MS procedures are utilized for Confirmation. Presumptively positive samples undergo washing before Confirmation as necessary. From Accessioning to Confirmation, the entire lab procedure is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
