Hair analysis is now widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures long-term drug and alcohol activity by embedding biomarkers within its fibers as it grows. When hair is obtained near the scalp, it can reveal substance use history for up to three months. This method of testing is straightforward to collect, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 strands (around the diameter of a #2 pencil) near the scalp, yields 100mg of hair, optimal for both initial testing and confirmation. For EtG, additional, or tests beyond 10 panels, a 150mg sample is advised. Using a jeweler's scale for weighing is suggested. In cases where scalp hair is not accessible, a similar quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair, while "body hair" applies to all other types such as facial and underarm hair.
Process Overview
The laboratory analysis of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's database, ensuring the sample's seal and correct shipment, assigning a unique Laboratory Accessioning Number (LAN), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening consists of a preliminary assessment for drug substances. Although Screening is an economical approach for testing probable drug presence in most samples, a positive result must be validated to be legally valid. Samples indicating potential positivity in Screening necessitate further verification.
When a sample presents as potentially positive during Screening, additional hair is extracted from the sample for Extraction. Here, substances are extracted at much lower concentrations compared to other techniques (such as urine or oral fluids), rendering hair drug analysis the most intricate methodology to execute.
Verification of any positive outcomes from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to verification, all likely positive samples undergo washing as required. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair classification and accredited to the ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests," the analysis actually evaluates the hair strand and does not involve the root beneath the scalp.
