Hair testing has evolved into an influential method for recognizing drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can offer nearly a 3-month detection period for alcohol and drug activities. Hair collection is straightforward, somewhat hard to tamper with, and conveniently transportable.
A 1.5-inch segment of roughly 200 strands (akin to the girth of a #2 pencil) adjacent to the scalp will yield 100mg of hair, the perfect amount for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It is advisable to weigh the sample on a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be utilized. When mentioning head hair, it pertains specifically to scalp hair. Body hair encompasses all other hair categories (facial, axillary, and so on).
Process Overview
The primary stages in the laboratory examination of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary integration of a sample into the lab's database. This step verifies proper sealing and shipment of the sample, assigns it a random LAN (Laboratory Accessioning Number), and completes any further data input absent in an electronic chain of custody framework.
Screening incorporates an initial swift analysis for drug presence. Although Screening is cost-efficient for eliminating drug usage in most samples, a positive result necessitates confirmation to hold up in legal contexts. Any samples marked as presumptively positive in Screening require follow-up confirmation.
If a sample is presumptively positive during Screening, additional hair is obtained from the original specimen for Extraction preparation. This step extracts drugs from hair at far lower concentrations than alternative methods (e.g., urine or oral fluid), which is why hair drug testing is notably challenging.
Confirmation of any positive screen involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo washing before confirmation, based on necessity. The comprehensive lab process from Accessioning to Confirmation falls under review guided by both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 norms.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", this test examines the hair strand rather than the follicle beneath the scalp.
