Hair testing is recognized as a potent mechanism for identifying drug and alcohol usage. The hair records a prolonged timeline of alcohol and drug use by embedding biomarkers within the fibers of the growing hair strand. If collected close to the scalp, hair offers nearly a 3-month period for detecting alcohol and drugs. Hair is easy to collect, relatively hard to adulterate, and simple to transport.
A 1.5-inch portion of approximately 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample size for screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is suggested. It is advised to weigh the specimen on a jeweler's scale. In cases where scalp hair isn't available, an equivalent amount of body hair may be used. Referring to head hair means scalp hair specifically. Body hair encompasses all other kinds (like facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial assimilation of a sample into a lab's system. This step verifies the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes supplementary data entry not included in an electronic chain of custody system.
Screening provides an initial assessment for drug presence. Though Screening is a cost-effective method for negating drug use in most samples, a positive result requires confirmation to be legally defensible. Any samples suspected positive in Screening need a secondary confirmation.
If a sample is suspected positive during Screening, additional hair is taken from the original specimen for Extraction. During this phase, drugs are drawn from hair at significantly lower concentrations as compared to other techniques (like urine or oral fluid), making hair drug screening the most challenging methodology to conduct.
Confirmation for any suspicious screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected positive are washed before confirmation as necessary. The whole laboratory workflow from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 accreditation standards.
