The use of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged historical record of alcohol and drug use by capturing biomarkers within the fibers of the hair as it grows. When taken close to the scalp, the hair can provide an approximately three-month detection period for alcohol and drugs. It is easy to collect, somewhat hard to tamper with, and simple to transport.
A 1.5-inch section containing roughly 200 hair strands (comparable to a #2 pencil in thickness) nearest to the scalp will yield 100mg, considered the perfect sample for both screening and confirmation. For EtG tests, additional panels, and tests exceeding 10 panels, 150mg is suggested. We advise using a jeweler's scale to weigh the sample. If there is no scalp hair available, a similar amount of body hair can be used. When mentioning head hair, it specifically pertains to scalp hair. Conversely, body hair includes all other hair varieties (facial, axillary, etc.).
Process Overview
Four key phases constitute the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially entering a sample into a laboratory's system. This procedure confirms that the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and concludes any extra data entry absent in an electronic chain of custody system.
Screening serves as an initial swift assessment for substances of abuse. Although Screening is cost-effective for ruling out drug use in most samples, any positive findings must be validated for legal admissibility. Any samples showing a presumptive positive in Screening necessitate further confirmation.
If a sample indicates a presumptive positive during the Screening stage, additional hair is extracted from the original specimen for the Extraction process. In this stage, drugs are extracted from hair at significantly lower concentrations than those found in other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging method to conduct.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as necessary before confirmation. The comprehensive lab process, from Accessioning to Confirmation, undergoes thorough review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
