Recognized as a strong detection method for substance use, hair testing offers prolonged insights into alcohol and drug consumption by capturing biomarkers within the strands of growing hair. Positioned near the scalp, hair samples can reveal a substance use record stretching back about 90 days for alcohol and drugs. Hair collection is straightforward, relatively challenging to alter, and easy to transport.
Obtaining a 1.5-inch segment from approximately 200 strands of hair (roughly comparable to the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for evaluation and verification. For EtG assessments, additional testing, or for panels exceeding 10, a 150mg sample is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair isn't accessible, a comparable quantity of body hair can be utilized. References to head hair pertain solely to scalp hair, while body hair includes all other hair types such as facial or axillary.
Process Overview
The laboratory procedure for processing drug test outcomes comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial stage of integrating a sample into a laboratory's workflow, ensuring correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening provides an initial evaluation for substance abuse indications. While cost-efficient in excluding drug usage in most cases, a positive screening result requires validation to be legally recognized. Samples with preliminary positive indications during Screening necessitate corroborative testing.
Should a sample indicate a potential positive result during Screening, additional hair is sourced from the original sample for the Extraction phase. This phase involves isolating drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), accounting for the complexity of conducting hair drug screenings.
Verification of any positive Screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Necessary washing of all tentative positive samples precedes confirmation. The complete laboratory process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accredited standards.
