Hair testing has garnered recognition as an effective method for detecting the use of drugs and alcohol. Within the growing hair strand, biomarkers get trapped, providing a long-term record of drug and alcohol use. When taken near the scalp, a hair sample can reveal alcohol and drug presence for a period of up to about three months. Collecting hair is straightforward, relatively difficult to tamper with, and convenient for shipping.
Securing a sample of approximately 1.5 inches and about 200 strands (comparable in size to a #2 pencil) nearest to the scalp will supply 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or analyses beyond 10 panels, it is advisable to gather 150mg of the hair sample. We advise using a jeweler's scale to measure the specimen weight. In the absence of scalp hair, a similar amount of body hair can be taken. Life when we mention head hair, we mean scalp hair specifically. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The fundamental steps in lab processing of drug test results consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the primary processing of a specimen into the lab's system, ensuring proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry that electronic methods didn’t cover.
Screening performs an initial fast assessment for drug abuse. Although it offers a cost-effective method to exclude drug use in many specimens, confirmation is imperative for court admissibility of positive screens. Samples indicated as presumptively positive in Screening must undergo secondary confirmation.
In cases where samples appear positive during Screening, additional hair is extracted from the original sample for preparation during Extraction. Drugs are retrieved from hair in this stage at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS methods validate any positive screening outcomes. Presumptive positive samples undergo necessary washing before confirmation. The complete lab process, spanning from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
