Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The hair encases chemical indicators in the fibers of the developing strand, offering a prolonged timeline of alcohol and drug usage. When taken from near the scalp, hair can offer nearly a 90-day detection period for substances. It is straightforward to collect, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest the scalp yields 100mg, suitable for screening and confirming results. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. Utilization of a jeweler’s scale for weighing the specimen is recommended. Should scalp hair be inaccessible, an equivalent portion of body hair may be utilized. “Head hair†pertains to scalp hair exclusively. “Body hair†includes all other forms of hair (facial, axillary, etc.).
Process Overview
The principal stages of laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary procedure of registering a sample into a lab’s database, ensuring it was correctly sealed and shipped, designating a random LAN (Laboratory Accessioning Number), and accomplishing any supplementary data input absent from an electronic custody chain.
Screening is a rapid initial evaluation for drug presence. Although cost-efficient for ruling out drug use in most samples, a positive screen must be confirmed for legal acceptability. Every sample yielding a presumptive positive in Screening mandates additional confirmation.
When a sample is presumed positive during Screening, extra hair is isolated from the original specimen and prepped for Extraction. At this juncture, drugs are separated from hair at a significantly reduced concentration compared to other techniques (e.g. urine or oral fluid), rendering hair drug screening the most challenging procedure.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed as necessary before confirmation. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 certification.
