Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by enclosing biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, hair can reveal up to an estimated 3-month timeframe for detecting alcohol and substances. It's easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch sample comprising around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg, the preferred quantity for screening and analysis. For EtG, additional tests, or tests above 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent quantity of body hair may be obtained. Regarding head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (such as facial or axillary hair).
Process Overview
Laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample into the lab's system. This step includes confirming proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and finishing any extra data entry not supplied by an electronic chain of custody system.
Screening is a preliminary inspection for substance abuse. Although Screening is a cost-effective method to eliminate drug use for most samples, a positive screen must be confirmed to be valid in legal settings. Samples that are presumptively positive in Screening require further confirmation.
If a sample tests presumptively positive during Screening, additional hair is taken from the original sample for Extraction. During Extraction, drugs are derived from hair at a much lower concentration than with other methodologies (such as urine or oral fluids), highlighting why hair drug screening is one of the most complex methodologies.
Confirmed positive screening results use GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples undergo washing before confirmation, as needed. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is commonly used, but the analysis targets the hair strand itself, not the follicle below the scalp.
