Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a lasting record of alcohol and drug usage by capturing biomarkers within the strands. When clipped near the scalp, hair can offer a detection duration of up to around 3 months for alcohol and other substances. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A sample measuring 1.5 inches containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation tests. For EtG tests, additional panels, or tests exceeding 10 panels, 150mg of hair is suggested. It is advised to use a jeweler’s scale for weighing the specimen. In the absence of scalp hair, an equivalent amount of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This process verifies that the sample is appropriately sealed and shipped, assigns a randomized LAN (Laboratory Accessioning Number), and completes any additional data input not captured by an electronic chain of custody system.
Screening involves conducting a preliminary rapid assessment for substances of abuse. Although Screening offers a cost-effective means to exclude drug use in most samples, a positive screen result must be confirmed to be legally valid in court. Samples that are provisionally positive in Screening necessitate a secondary affirmation.
When a sample is tentatively positive during the Screening phase, further hair is extracted from the initial specimen and readied for Extraction. During this phase, substances are extracted from hair at a much lower concentration compared to other techniques (e.g., urine or oral fluid), attributing to the challenge in performing hair drug screening.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned as necessary before confirmation. The complete lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
