Hair assessments have gained traction as an effective method for detecting drug and alcohol intake. Hair strands offer an extensive timeline of substance use by embedding biomarkers within their fibers as they grow. When collected near the scalp, the hair can provide a detection span of up to about three months for alcohol and other drugs. Hair sampling is straightforward, challenging to tamper with, and convenient for transport.
A sample of 1.5 inches consisting of roughly 200 hair fibers (comparable to a #2 pencil's width) nearest to the scalp yields 100mg—this amount is optimal for both screening and confirmation. For Ethyl Glucuronide (EtG), add-ons, and/or panels exceeding 10, a specimen amount of 150mg is suggested. We advise using a jeweler's scale for weighing purposes. In the absence of scalp hair, an equivalent volume of body hair may be acquired. References to head hair pertain solely to scalp hair, while body hair denotes all other types (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial incorporation of a sample into the laboratory's system. It involves confirming the sample's sealed and proper shipment, assigning a random Laboratory Accessioning Number (LAN), and finalizing any supplementary data entry not provided by an electronic chain of custody system.
Screening involves an initial swift detection of drugs of misuse. While Screening is a cost-efficient method to rule out drug use in most instances, confirmation is necessary for screen-positive results to be legally admissible. Samples with presumptively positive screenings require further confirmation.
On presuming positivity in the Screening phase, additional hair is extracted from the original specimen for Extraction. This process extracts drugs from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any screening-identified positive result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as requisite. The comprehensive laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and conforms to the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Even though commonly termed as "hair follicle tests", the analysis is conducted on the hair strand and not the follicle beneath the scalp.
