The utilization of hair testing has gained recognition as an effective method for uncovering drug and alcohol consumption. Hair serves as a repository of long-term evidence for alcohol and drug use by embedding biomarkers within the fibers of the hair strand as it grows. When taken from close to the scalp, hair can reveal signs of alcohol and drug presence spanning approximately three months. It is straightforward to gather, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches in length, consisting of around 200 hair strands (comparable to the width of a #2 pencil) cut closest to the scalp, will yield approximately 100mg of hair, which is the preferred sample size for both screening and confirmation purposes. For EtG, add-ons, and/or panels above 10, a 150mg sample is advisable. It is recommended to measure the sample weight using a jeweler's scale. In instances where scalp hair is not an option, an equivalent portion of body hair is permissible. Notably, references to head hair should be understood as scalp hair specifically, while body hair includes all other hair types (such as facial and axillary).
Process Overview
There are four principal steps involved in the laboratory processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a specimen into the laboratory’s record-keeping system, including verifying proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody.
Screening entails a rapid preliminary examination for substances of abuse. Although Screening serves as an economical means to dismiss drug use in most cases, a positive screen must be followed by confirmation to stand in legal proceedings. Samples that yield provisional positive results during Screening require additional confirmation.
If the Screening stage yields a presumptively positive result, additional hair is extracted from the original sample and prepped for Extraction. In this phase, substances are extracted from the hair at significantly lower concentrations than with alternative methods (such as urine or oral fluid), which accounts for the greater complexity of hair drug screening.
Confirmation of any positive result from Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory process, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
