Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the fibers of the growing hair, it offers a comprehensive record of alcohol and drug use over time. Collected near the scalp, hair samples can potentially indicate substance usage over a span of up to three months. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section of around 200 strands (approximately the thickness of a #2 pencil) from the scalp yields 100mg, the preferred quantity for screening and confirmation. For tests like EtG, add-ons, and tests exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't available, an equivalent portion of body hair can be used. Our term "head hair" specifically refers to scalp hair, whereas "body hair" covers all other categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample’s initial processing in a laboratory system, including proper sealing and shipment confirmation, random LAN (Laboratory Accessioning Number) assignment, and completing any missing data entry from non-electronic chain of custody systems.
Screening is a preliminary examination for drugs of misuse. Although cost-effective for ruling out drug presence in most samples, a positive screening necessitates confirmation for legal acceptability. Samples presumed positive require further confirmation.
If a sample shows a presumptive positive during Screening, additional hair is extracted from it and readied for Extraction. Here, drugs are isolated from the hair in much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most intricate method to conduct.
For any presumptive positives, Confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are tentatively positive are cleaned before confirmation as needed. The complete laboratory procedure from Accessioning through Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often called "hair follicle tests," these actually analyze the hair strand rather than the follicle beneath the scalp.
