Hair testing has gained recognition as an effective instrument for identifying drug and alcohol consumption. It offers an extended historical record by capturing biomarkers within the strands of hair as they grow. Hair, when taken close to the scalp, provides an approximate detection period of three months for drugs and alcohol. The collection process is straightforward, hard to tamper with, and convenient for shipping.
A 1.5-inch sample comprising about 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the preferred amount for initial and confirmatory testing. For EtG, additional tests, or panels exceeding ten, 150mg is suggested. Using a jeweler’s scale to measure the specimen is advisable. Should scalp hair be absent, a similar quantity of body hair may be obtained. Head hair explicitly denotes scalp hair, while body hair encompasses other types such as facial and axillary.
Process Overview
The laboratory procedures for analyzing a drug test result consist of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the sample’s introduction into a lab's system. This includes checking the sample’s seal and shipping correctness, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not handled by an electronic chain of custody system.
Screening is a preliminary inspection for drug abuse. Although Screening is economical for excluding drug usage in most samples, any positive result must undergo confirmation to hold up in court. Samples that are tentatively positive in Screening necessitate a follow-up confirmation.
In case of a presumptive positive during Screening, additional hair is taken from the original specimen for Extraction. Here, drugs are extracted from hair at a much lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to conduct.
The Confirmation step for any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if required. The laboratory procedure from Accessioning to Confirmation is reviewed for adherence to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
