Hair testing is recognized as an effective means for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of an emerging hair strand, hair provides a prolonged record of alcohol and drug usage. When snipped near the scalp, hair can reveal up to roughly a three-month detection span for drugs and alcohol. It's straightforward to gather, resistant to tampering, and simple to dispatch.
A 1.5-inch segment comprising approximately 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for scrutiny and verification. For EtG, supplementary tests, or those exceeding 10 panels, the recommendation is 150mg of the specimen. We advise assessing the specimen's weight with a jeweler's scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be gathered. References to head hair relate strictly to scalp hair. Body hair encompasses all other hair categories (such as facial, axillary, etc.).
Process Overview
The laboratory evaluation of drug test results involves four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into a lab's framework. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any outstanding data input absent from an electronic chain of custody system.
Screening consists of a preliminary fast analysis for drugs of misuse. Although Screening is a cost-effective method to exclude drug use in the majority of samples, a positive screen must undergo confirmation to be valid in legal settings. Samples that test presumptively positive in Screening necessitate secondary confirmation.
When a sample tests presumptively positive during the Screening phase, additional hair is drawn from the initial specimen and readied for Extraction. This step involves extracting drugs from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), marking hair drug screening as a challenging methodology to execute.
Confirmation of any positive Screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a cleansing before confirmation if needed. From Accessioning to Confirmation, the entire laboratory process is reviewed under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.
