The utilization of hair analysis has garnered recognition as an effective method for unveiling the consumption of drugs and alcohol. Hair, by integrating biomarkers within the threads of its developing strands, unveils a protracted timeline of substance usage. When gathered near the scalp, hair extends up to a 3-month detection span for alcohol and various drugs. It is straightforward to gather, less susceptible to tampering, and convenient for shipping.
A 1.5-inch segment comprising about 200 hair strands (equivalent to a #2 pencil's girth) taken nearest to the scalp yields 100mg of hair, the preferred quantity for initial examination and verification. For extended analyses, like EtG or tests exceeding 10 panels, 150mg of hair is advisable. The measurement of the sample should ideally be conducted using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair can be collected. When "head hair" is mentioned, it specifically denotes scalp hair. The term "body hair" includes all other hair varieties (beard, underarm, etc.).
Process Overview
The laboratory procedure for processing drug test outcomes involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial phase of integrating a sample into a lab's database. This includes confirming the proper sealing and shipping of the sample, designating a unique LAN (Laboratory Accessioning Number), and finalizing any necessary data input absent from an electronic chain of custody framework.
Screening consists of a preliminary rapid assessment for drug presence. While Screening serves as a cost-efficient solution to exclude drug usage in the majority of specimens, a positive result necessitates confirmation for legal validation. Any specimens showing presumptive positivity in Screening require subsequent confirmation.
If Screening suggests positivity, additional hair from the original sample is allocated for the Extraction phase. This process extracts drugs from hair in significantly lower concentrations than alternative methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
To confirm any positive initial results, GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed. All samples with presumptive positivity undergo washing prior to final confirmation if needed. The entire laboratory sequence from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and accreditation per ISO/IEC 17025 standards.
