Hair assessments are regarded as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing markers within the strands' fibers as they grow. When gathered near the scalp, hair can provide a detection span of up to around 3 months for substances. Hair is easy to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, considered the best sample size for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair can be used. Head hair pertains to scalp hair exclusively. Body hair includes all other types like facial or axillary hair.
Procedure Summary
The vital stages in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a lab's system. This involves ensuring the sample was correctly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included in an electronic chain of custody system.
Screening performs a preliminary swift assessment for drugs. While it is a cost-effective measure to eliminate drug usage in most samples, a positive result needs further validation to be court-acceptable. Samples showing presumptive positive in Screening necessitate secondary verification.
Should a sample's Screening phase return presumptive positive, additional hair is extracted from the initial specimen for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), rendering hair drug evaluations the toughest procedures to conduct.
Confirmation of any positive screen outcome is conducted via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The full lab procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.
