Hair testing has gained recognition as a potent method for detecting drug and alcohol consumption. Hair captures a long-term history by trapping biomarkers within the fibers of the growing hair. Collected near the scalp, it offers up to a 3-month detection window for substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch portion comprising about 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is an optimal sample for both screening and confirmation. For EtG, added tests, or panels exceeding 10, a sample of 150mg is advised. The use of a jeweler’s scale to measure the sample is recommended. If scalp hair is unavailable, an equivalent amount of body hair can be used. Note that head hair refers specifically to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of handling a sample within the laboratory system. This process includes verifying proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data entry not available from an electronic chain of custody.
Screening is a preliminary, quick check for drug presence. Although cost-effective for excluding drug usage in most samples, a positive result in screening must be confirmed for legal validity. Samples that test presumptively positive in screening require a secondary confirmation.
In cases of presumptive positivity during Screening, additional hair from the initial specimen is extracted. During Extraction, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.
Confirmation for any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as necessary. The entire process from Accessioning to Confirmation adheres to the CAP Hair designation and ISO / IEC 17025 standards.
