Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It offers a comprehensive timeline by embedding biomarkers within the strands of advancing hair. When taken close to the scalp, hair can reveal consumption of alcohol and drugs for up to an estimated three-month period. Hair collection is straightforward, hard to tamper with, and is convenient to mail.
A 1.5-inch hair sample (approximately 200 strands, the size of a #2 pencil) nearest to the scalp provides 100mg, the optimal amount for both screening and verification. For tests like EtG and others that exceed 10 panels, a specimen weighing 150mg is advised. Assessing specimen weight on a jeweler’s scale is suggested. If scalp hair isn't available, a comparable quantity of body hair can be used. In this context, head hair strictly implies scalp hair. Body hair encompasses all other forms (like facial and axillary).
Process Overview
The laboratory processing of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the sample's primary processing within a lab's system. This process ensures proper sealing and shipping of the sample, the allocation of a random LAN (Laboratory Accessioning Number), and the completion of any extra data entry absent from an electronic chain of custody.
Screening acts as an initial, swift evaluation for drug abuse substances. While Screening is a budget-friendly method for negating drug usage for most samples, any positive findings must be validated for court acceptance. Presumptive positives in Screening require additional confirmation.
If a sample shows presumptive positivity at Screening, more hair from the initial sample undergoes preparation for Extraction. In Extraction, drugs are isolated from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), highlighting why hair drug analysis is the most intricate method to execute.
Validation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo necessary cleansing before confirmation. The entire lab sequence, from Accessioning to Confirmation, is governed by the CAP (College of American Pathologists) Hair accreditation and adheres to ISO / IEC 17025 standards.
