Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. The hair captures a detailed record of alcohol and substance intake by embedding biomarkers within the fiber structure of the growing strand. When obtained near the scalp, hair can offer a detection timeline of up to around 3 months for alcohol and drugs. It is easy to gather, challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to a #2 pencil size) nearest to the scalp, yields 100mg, which is the optimum sample size for preliminary and subsequent testing. For EtG, additional tests, and/or screenings beyond 10 panels, 150mg of hair is suggested. We advise using a jeweler’s scale for weighing the specimen. If scalp hair is not obtainable, an equal quantity of body hair may be an alternative. By head hair, we specify scalp hair only. All other hair types (such as facial, axillary, etc.) are classified as body hair.
Process Overview
The key stages in the laboratory handling of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the initial preparation of a sample into a lab's framework. It involves ensuring the sample's seal and shipment were executed correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling additional data entries that might be essential beyond the electronic chain of custody documentation.
Screening offers an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient approach to exclude drug usage in most cases, a confirmed positive screen is essential for legal admissibility. Any samples flagged as presumptively positive in Screening necessitate further confirmation.
For samples marked as presumptively positive in the Screening phase, additional hair is extracted from the original sample for the Extraction process. At this stage, substances are removed from hair at a lower concentration than seen in other methods (such as urine or oral fluid), which highlights the complexity of hair drug screening processes.
Confirmation of all positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is reviewed in accordance with both CAP (College of American Pathologists) Hair guidelines and accreditation under ISO / IEC 17025 standards.
