Hair analysis has evolved into an effective means for uncovering alcohol and drug use. Hair strands retain drug and alcohol markers within the fibers as they grow, offering a prolonged history of substance use. When sourced near the scalp, hair can reveal drug and alcohol consumption for an estimated 90-day period. Collection is straightforward, alteration is challenging, and transport is uncomplicated.
A hair sample of 1.5 inches, roughly equivalent to 200 strands (about the diameter of a #2 pencil), provides 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, or assessments exceeding 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for weighing. In the absence of scalp hair, a similar volume of body hair may be utilized. "Head hair" is specific to scalp hair only, while "body hair" encompasses all other types (facial, axillary, etc.).
Procedure Breakdown
The laboratory procedure for processing a drug test result consists of four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample processing within a laboratory’s framework. This process confirms the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and concludes any supplementary data entries absent from an electronic chain of custody system.
Screening serves as an initial inspection for substances of abuse. Screening offers a cost-effective method to negate drug usage across most samples, but any positive results necessitate verification to be legally admissible. Samples indicating preliminary positives in Screening must undergo secondary validation.
Should a sample appear preliminarily positive in Screening, additional hair from the initial supply is prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than seen in alternative methodologies (e.g., urine or oral fluid), solidifying hair drug testing as the most intricate method to conduct.
Verification of any positive screening outcome is executed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as warranted. The complete laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.
