Hair examinations have emerged as an essential method for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. When samples are taken close to the scalp, they can offer a detection period of up to roughly 90 days for alcohol and drugs. Hair collection is straightforward, comparatively challenging to tamper with, and convenient for transportation.
An ideal sample for testing and verification is a 1.5-inch section, approximately 200 strands (similar to the size of a #2 pencil), close to the scalp, providing 100mg of hair. For EtG, supplementary tests, and assessments exceeding 10 panels, a 150mg portion is advised. It's advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair can be used. "Head hair" denotes only scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The key phases in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the laboratory's system. It includes verifying the appropriate sealing and shipment of the sample, issuing a random LAN (Laboratory Accessioning Number), and completing any additional data input missing from an electronic chain of custody system.
Screening comprises a preliminary rapid assessment for abusive drug use. Although Screening is an economical approach to exclude drug usage in most samples, a positive outcome must be validated to be legally valid. Samples that test presumptively positive in Screening require secondary confirmation.
When a sample tests presumptively positive during Screening, more hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration level than other techniques (e.g., urine or oral fluid), making hair drug testing the most complex methodology.
Any positive results in the Screening phase undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned as needed before confirmation. The entire laboratory procedure, from Accessioning to Confirmation, is overseen according to the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
