Hair testing is now considered a robust method for discovering drug and alcohol consumption. Hair strands capture biomarkers as they grow, offering an extensive record of alcohol and other drug use. When gathered near the scalp, these strands allow for detection of substances over three months. The collection process is straightforward, tampering proves challenging, and shipping is hassle-free.
A 1.5-inch segment comprising roughly 200 hair strands (similar to the girth of a #2 pencil), taken from near the scalp, provides 100mg, which is optimal for an initial test and confirmation. For specific tests like EtG or those beyond 10 panels, a specimen weighing 150mg is advisable. Utilizing a jeweler’s scale for weighing is suggested. In cases where scalp hair is insufficient, body hair an equivalent measure can be used. References to head hair specifically denote scalp hair, while body hair encompasses all other types (such as facial or axillary).
Process Overview
The laboratory processing of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first entered into the laboratory's system, ensuring it was sealed and transported properly. A random LAN (Laboratory Accessioning Number) is assigned, and any additional necessary data entry not managed by an electronic chain of custody system is completed.
Screening offers a preliminary assessment for illicit substances. While cost-effective for ruling out drug use in most samples, positive screenings require confirmation to be valid for legal purposes. Any sample flagged as presumptively positive during this step requires further verification.
If Screening suggests a positive result, more hair from the original sample is extracted and readied for detailed analysis. Drugs are retrieved from the hair at lower concentrations compared to other testing methods (like urine or oral fluids), making hair screening one of the most technical methods performed.
Verification of positive screening outcomes utilizes techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Every sample with a presumptive positive result undergoes washing before confirmation as necessary. The entire laboratory sequence, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly called "hair follicle tests," these tests actually analyze the hair strand, not the follicle beneath the scalp.
