Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the strands of the developing hair. Collecting hair near the scalp can offer up to around a three-month timeframe for detecting alcohol and other substances. The collection process is straightforward, it is relatively resistant to tampering, and shipping is uncomplicated.
A segment of 1.5 inches, comprising approximately 200 hair strands (resembling the diameter of a #2 pencil) adjacent to the scalp yields 100mg of hair, which is the preferred sample size for both screening and confirming. For EtG, add-ons, and tests exceeding 10 panels, a 150mg specimen is advised. Measuring the specimen on a jeweler’s scale is recommended. If scalp hair is not available, a comparable amount of body hair may be gathered. When mentioning head hair, we mean only scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The primary steps in laboratory drug test result processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial entry into a laboratory’s framework. This incorporates verifying the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data required outside of an electronic chain of custody system.
Screening conducts an initial rapid assessment for substances. Though Screening is a resourceful method to eliminate drug use in most samples, a positive screening requires confirmation to be court-admissible. Any samples preliminarily positive in Screening necessitate secondary confirmation.
If there's an initial positive result in the Screening stage, additional hair is extracted from the original specimen for Preparation. Here, drugs are extracted from hair in significantly lower concentrations than in other techniques (e.g., urine or saliva), making hair drug analysis one of the most challenging methods.
Positive screening results are affirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
