Seen as a robust method for identifying drug and alcohol intake, hair testing captures biomarkers in the strands of hair as they grow. When collected near the scalp, hair can reveal drug and alcohol usage over a period of up to about 90 days. The collection of hair is straightforward, relatively resistant to tampering, and straightforward to dispatch.
A segment of hair measuring 1.5 inches, with roughly 200 strands (about the diameter of a #2 pencil) closest to the scalp, yields 100mg, which is optimal for analysis. For EtG add-ons and/or tests beyond 10 panels, it is advised to use 150mg. Calibration of the sample on a jeweler’s scale is encouraged. In instances where scalp hair is unobtainable, a similar volume of body hair may be utilized. Head hair pertains solely to scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The drug testing lab procedure involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of integrating the sample into the lab's system, verifying proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any extra data input beyond the electronic chain of custody system.
Screening executes an initial scan for drug presence. It’s an economical preliminary method for ruling out drug use in most cases, though a positive requires confirmation to be legally valid. Samples that yield a presumptive positive in Screening need further verification.
If Screening suggests positivity, additional hair from the original sample is utilized for Extraction. Here, drugs are extracted at lower concentrations than in other methods (such as urine or oral fluids), highlighting the complexity of hair drug screening.
Confirmation of positive results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo washing before confirmation as needed. The whole process, from Accessioning to Confirmation, follows the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
