Hair screening is recognized as an effective resource for identifying alcohol and drug use. Hair holds a prolonged history of substances by encapsulating biomarkers within the strands of growing hair. When taken close to the scalp, it can offer nearly a 3-month window for detecting substances. The collection of hair is straightforward, relatively hard to tamper with, and convenient for transport.
A sample of 1.5 inches with about 200 hair strands (approximately the width of a #2 pencil) closest to the scalp provides 100mg, which is the optimal quantity for assessment and verification. For EtG assessments, additional tests, and those exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale to measure the sample is recommended. Should scalp hair be inaccessible, an equivalent mass of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" applies to all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the foundational step of processing a sample into the system of a laboratory. This process entails ensuring the sample is properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic custody chain system.
Screening serves as an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to dismiss the drug use in most samples, a positive screen needs to be corroborated to hold up in legal settings. Samples indicating a presumptive positive in Screening demand a follow-up confirmation.
Should a sample be tentatively positive during Screening, additional hair is extracted from the original sample for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than in alternative methodologies (e.g., urine or oral fluid), rendering hair drug screening the most intricate technique.
Confirmation for any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The comprehensive laboratory course from Accessioning to Confirmation is reviewed under both CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
