Hair analysis is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a chronological record of substances by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection period extending up to three months for alcohol and drugs. Hair is easy to gather, difficult to tamper with, and convenient to mail.
A 1.5-inch segment comprising roughly 200 hair strands (approximately equivalent to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal quantity for both initial screening and confirmation. For EtG, additional tests, or those surpassing 10 panels, a specimen of 150mg is advisable. We suggest weighing the sample with a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be obtained. When discussing head hair, it refers exclusively to scalp hair. Body hair encompasses other types (facial, underarm, etc.).
Procedure Overview
The primary components of laboratory processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's system. This entails verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data recording not provided by an electronic chain of custody system.
Screening offers a preliminary examination for drugs. Although Screening is an economical method to exclude drug usage in the majority of samples, a confirmed positive screen is necessary for legal validity. Samples that result presumptively positive in Screening require secondary confirmation.
If the Screening process suggests a positive result, additional hair from the initial sample is prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is more challenging to conduct.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
