The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair stores a prolonged record of alcohol and drug use by embedding biomarkers in the growing hair fibers. When gathered near the scalp, hair can offer a detection span of up to around 3 months for drugs and alcohol. Its collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment comprising roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a specimen weighing 150mg is suggested. It's advisable to weigh the specimen using a jeweler's scale. If scalp hair cannot be obtained, an equal volume of body hair might be used. When mentioning head hair, we refer solely to scalp hair. Body hair denotes all other forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial integration of a sample into a lab's system. This stage ensures the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data entry missing from an electronic chain of custody system.
Screening provides an initial swift detection of drugs. While efficient for excluding drug use in most samples, a positive screening must be confirmed for court acceptance. Any samples deemed positive in Screening require further validation.
Samples showing positive results in the Screening stage undergo more hair extraction from the original specimen for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), hence why hair drug screening is considered the most challenging technique.
Confirmation of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
