Hair analysis is recognized as a significant method for uncovering both drug and alcohol consumption. This technique offers an extended insight into substance use by encasing biomarkers within the strands of growing hair. When clipped near the scalp, hair samples can reveal a drug and alcohol history of approximately 3 months. The collection process is straightforward, somewhat resistant to tampering, and facilitates easy shipping.
A 1.5-inch segment comprising about 200 hair strands (similar in size to #2 pencil lead) near the scalp yields 100mg, which is ideal for testing and validation. For EtG, extended tests, or more than 10-panel tests, a 150mg sample is advisable. We suggest measuring it using a jeweler’s scale. Should scalp hair be unavailable, an equivalent portion of body hair can be used. In this context, head hair refers solely to scalp hair. Body hair encompasses all other types (e.g., facial, underarm, etc.).
Process Overview
The procedure at the lab for generating a drug test outcome comprises four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial reception of a sample into the lab’s database. It involves verifying the proper sealing and transport of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing further data entry not covered by an electronic chain of custody.
Screening is a preliminary rapid assessment for substance misuse. Although Screening is a cost-efficient strategy for ruling out drug use in many samples, results deemed positive in this initial stage must be further validated for legal purposes. Any samples testing positive during Screening undergo an additional confirmation.
For samples testing presumptively positive during Screening, a further portion of hair is extracted from the original sample for the Extraction process. This step involves removing drugs from hair at concentrations much lower than other methods (such as urine or saliva), highlighting the complexity of hair drug testing.
Confirmation of positive Screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples presumed positive undergo washing before Confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is conducted under the oversight of CAP's (College of American Pathologists) Hair protocols and ISO / IEC 17025 accreditation.
