Hair testing has emerged as an effective mechanism for identifying the use of drugs and alcohol. Hair offers a prolonged history of alcohol and other substances by encapsulating biomarkers within the strands of hair as they grow. When hair is collected near the scalp, it can reveal a detection window of up to about 3 months for alcohol and drugs. The process of collecting hair is straightforward, relatively challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is ideal for both initial screening and confirmation tests. For tests involving EtG, additional panels, or beyond 10 panels, it is advised to gather 150mg of the sample. Utilizing a jeweler's scale for weighing the specimen is recommended. If scalp hair is not available, an equivalent quantity of body hair can be utilized. The term "head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary).
Process Overview
The process of laboratory testing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the laboratory’s system. This stage includes the validation of the sample's sealing and shipping, assigning it a random Laboratory Accessioning Number (LAN), and completing any further data entry that the electronic chain of custody system might not cover.
Screening serves as a preliminary swift check for drugs of abuse. While Screening is economical for excluding drug usage in most samples, a positive screen must be verified for it to be court-admissible. Samples indicated as presumptively positive during Screening need additional confirmation.
If Screening indicates that a sample is presumptively positive, additional hair is extracted from the original sample and processed for Extraction. During Extraction, drugs are extracted from hair at much lower concentrations compared to other methods (like urine or oral fluid), making hair drug screening the most challenging methodology.
Confirmation for positive screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive undergo washing before confirmation if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under the College of American Pathologists (CAP) Hair designation and adheres to ISO / IEC 17025 standards.
