Hair analysis is now regarded as a significant technique for identifying substance and alcohol consumption. The hair encapsulates a long-term record of alcohol and drug use through biomarkers ensnared in the strands of the elongating hair. When gathered near the scalp, hair can offer roughly a 3-month lookout period for the presence of alcohol and narcotics. Hair collection is straightforward, relatively immune to tampering, and simple for transport.
A sample measuring 1.5 inches comprising about 200 hair strands (approximately the thickness of a #2 pencil) adjacent to the scalp will yield 100mg of hair, the optimal amount for both examination and verification. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If hair from the scalp is not available, an equivalent quantity of body hair may be obtained. When talking about head hair, it refers specifically to scalp hair. Body hair denotes all other types (e.g., facial, axillary).
Process Overview
The primary steps in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample inside a laboratory’s records system. This encompasses confirming the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by an electronic chain of custody setup.
Screening executes an initial rapid inspection for substances of abuse. This step is a budget-friendly means to dismiss drug engagement in most samples, yet a positive screening result must be affirmed to be valid in judicial settings. Any samples yielding a preliminary positive in Screening necessitate a further confirmation round.
Where a sample reveals a preliminary positive during the Screening phase, extra hair is drawn from the original sample for the Extraction phase. Here, substances are extracted from hair at notably lower concentrations unlike in other strategies (such as urine or oral fluids), underlining why hair drug screening is a more complex strategy to administer.
Affirmations of any positive screening outcome occur via GC/MS, GC/MS/MS or LC/MS/MS. All initial positive samples are cleansed before confirmation when required. The full laboratory operation from Accessioning to Confirmation undergoes review following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
