Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug intake by encapsulating biomarkers within the strands as they grow. When taken from near the scalp, hair offers a detection window for alcohol and drug use of up to roughly three months. Hair is straightforward to procure, relatively challenging to tamper with, and convenient for transport.
A 1.5-inch segment consisting of around 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weighing 150mg is advisable. It is suggested to measure the specimen using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair may be used. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the preliminary stage of integrating a sample into a lab’s database. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional information not covered by an electronic chain of custody system.
Screening performs an initial evaluation for illegal drugs. Although Screening is an economical method to exclude drug usage in the majority of cases, a positive result must be verified for legal admissibility. Any samples showing presumed positivity in Screening require secondary confirmation.
If a sample returns a tentative positive during Screening, additional hair from the original sample is prepared for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than those from other methods (ex. urine or oral fluid), making hair drug tests the most challenging to conduct.
Confirmation of any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
