Hair examinations have gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug intake by capturing biomarkers within the structure of the hair as it grows. When gathered near the scalp, hair can offer a detection window of up to roughly three months for alcohol and various drugs. Collection is straightforward, tampering is challenging, and it is convenient to mail.
A segment of 1.5 inches consisting of roughly 200 hair strands (enough to match the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for testing and verifying. For EtG, additional substances, and/or more than 10-panel tests, a specimen quantity of 150mg is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair may be used. When discussing head hair, we mean scalp hair specifically. Body hair includes all other hair forms (like facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result within a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial steps of entering a sample into a lab's system, which involves ensuring the sample is sealed and delivered correctly, assigning a random LAN (Laboratory Accessioning Number), and inputting extra data not available via electronic custody records.
Screening acts as a preliminary rapid test for drug misuse. Though Screening is an economical method to dismiss drug use in most samples, any positive results necessitate confirmation for legal validity. Samples that appear positive during Screening must undergo further confirmation.
Should Screening indicate a presumptive positive, more hair is extracted from the original sample for Extraction. Here, substances are isolated from hair at a much finer concentration than other methods (for instance, urine or oral fluid), making hair drug screening the most challenging approach.
Confirmation of any positive findings from Screening is conducted using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive specimens are cleansed before confirmation as required. The complete lab procedure from Accessioning to Confirmation is conducted under both the guidelines of the CAP (College of American Pathologists) Hair designation and the accreditation aligning with ISO / IEC 17025 standards.
