Hair analysis is now viewed as an effective method for detecting substance use. Hair captures a lengthy record of substance intake by embedding biomarkers in its fibers. When cut near the scalp, hair offers an observation period of nearly 90 days for various substances. Collecting hair samples is straightforward, relatively tamper-proof, and convenient for shipping.
A 1.5-inch hair portion, consisting of around 200 strands (comparable to a #2 pencil's diameter) next to the scalp provides 100mg, optimal for both screening and verification. For EtG, inclusive tests, and/or assessments exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weight measurement is recommended. If scalp hair can't be obtained, an equivalent quantity of body hair is acceptable. The term head hair refers solely to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results is comprised of four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the sample's initial introduction into the lab’s system. This procedure ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes additional data input not available through electronic chain of custody systems.
Screening performs a preliminary check for illicit substances. Although Screening economically eliminates probable drug use in many samples, any positive result must be confirmed to hold legal validity. Samples testing positive in Screening necessitate further confirmation.
Should a sample test positive during Screening, additional hair is taken from the main sample and prepped for Extraction. At this point, drugs are removed from hair at much lower levels compared to other methods (e.g., urine or oral fluid), positioning hair analysis as a complex testing method.
Confirmation of all positive screens is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo cleaning before confirmation as needed. The comprehensive lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and compliant with ISO / IEC 17025 standards.
