Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair is capable of providing a prolonged history of substance use by embedding biomarkers within the hairs' fibers as they grow. When collected near the scalp, hair can indicate up to a three-month period of substance use detection. Hair is easy to collect, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches and consisting of about 200 strands (roughly the width of a #2 pencil) closest to the scalp will provide 100mg of hair, which is considered optimal for both screening and confirmation. For EtG evaluations, additional tests, or tests exceeding 10 panels, a 150mg sample is suggested. Utilizing a jeweler's scale to weigh the sample is recommended. If scalp hair is not available, an equivalent amount of body hair can be used. Head hair refers specifically to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial step of registering a sample within a lab's system. This step includes confirming the sample's integrity during sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening involves a preliminary examination for the presence of drug substances. Screening offers a cost-efficient approach to exclude drug use in most samples, but any positive results from Screening must undergo confirmation for court admissibility. Samples yielding presumptive positive results require further validation.
When a sample indicates a presumptive positive outcome during Screening, additional hair from the specimen is prepared for Extraction. During this phase, drugs are retrieved from the hair at lesser concentrations compared to methods like urine or oral fluid analysis, which makes hair drug testing one of the most challenging methodologies.
Positive screening results are verified using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. From Accessioning through Confirmation, the complete laboratory process is reviewed under the CAP (College of American Pathologists) Hair specialty and ISO / IEC 17025 standards.
