Hair testing is now widely recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol usage by retaining biomarkers within the strands of growing hair. Collected near the scalp, hair can reveal use of alcohol and other substances over roughly a 3-month period. It's easy to collect, challenging to tamper with, and simple to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (comparable in size to a #2 pencil) closest to the scalp will yield 100mg of hair, suitable for both screening and confirmation. For tests like EtG or those exceeding 10 panels, a 150mg sample is advised. It’s best to weigh the hair using a jeweler's scale. If scalp hair can't be obtained, an equivalent amount of body hair can be collected. "Head hair" denotes only scalp hair, while "body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
The laboratory analysis of a drug test result includes four major steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is processed into the laboratory's system. This step ensures the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional necessary data entry if not available through an electronic chain of custody system.
Screening serves as the initial rapid check for illegal drug presence. While Screening helps to economically rule out drug use in most samples, positive screening tests must be confirmed to be valid in legal settings. Presumptive positives from Screening require subsequent confirmation.
If a sample shows a presumptive positive result during Screening, additional hair is extracted from the sample for processing in Extraction. At this stage, drugs are separated from hair in much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening particularly challenging to perform.
Confirmation of any positive results from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing when necessary. The full laboratory procedure from Accessioning to Confirmation is conducted under the framework of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
