Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a record of long-term alcohol and drug use by embedding biomarkers within the fibers of hair as it grows. When taken close to the roots, hair can reveal a usage pattern up to roughly a three-month period for alcohol and other substances. Hair samples are easy to collect, challenging to tamper with, and straightforward to transport.
A strand segment of 1.5 inches comprising about 200 hairs (roughly equivalent to the width of a #2 pencil) near the roots will yield 100mg, which is the preferred quantity for both initial testing and subsequent validation. For EtG analysis, additional options, and/or tests exceeding ten panels, a specimen of 150mg is advisable. It is suggested to determine the specimen's weight using a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair can be obtained. In context, head hair refers only to scalp hair, while body hair includes all other types (like facial, underarm, etc.).
Process Overview
The four key procedures involved in processing a drug test in a laboratory are: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary integration of a sample into the lab's processes. This step confirms the sample's proper sealing and delivery, generates a random LAN (Laboratory Accessioning Number), and finalizes additional data input not included in an electronic chain of custody system.
Screening entails an initial, speedy examination for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug use in most specimens, a positive outcome must be validated to support legal admissibility. All presumptively positive samples in Screening necessitate a secondary verification.
When a sample is potentially positive during the Screening phase, additional hair is extracted from the initial sample and prepared for the Extraction phase. In this stage, drugs are retrieved from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which accounts for the complexity of hair drug screening.
Any positive result from screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples predicted to be positive are cleansed before confirmation as necessary. The laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
