Hair testing is viewed as an effective mechanism for identifying drug and alcohol consumption. Hair captures a lasting record of alcohol and drugs by preserving biomarkers within the strands as they grow. When sourced from near the scalp, hair offers an approximate detection period of up to 90 days for substances. Collection is straightforward, tampering is challenging, and it is simple to transport.
A sample measuring 1.5 inches, containing roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is ideal for both screening and confirmation processes. For EtG, additional tests, and/or panels exceeding 10, a quantity of 150mg is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. Should scalp hair be unavailable, an equal quantity of body hair may be used instead. References to head hair pertain solely to scalp hair, while body hair covers all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial introduction of a sample into a lab’s system. It involves confirming the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening conducts an initial swift assessment for drugs of concern. While it’s a cost-effective method to exclude drug use for the majority of samples, to be valid legally, a positive screen requires confirmation. Samples considered presumptively positive during Screening demand subsequent confirmation.
Once a sample tests presumptively positive in the Screening phase, additional hair from the original sample is prepared for Extraction. In this phase, drugs are retrieved from hair at far lower concentrations than other techniques (e.g., urine or oral fluid), rendering hair drug testing the most challenging method to execute.
Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as necessary. The full laboratory sequence, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
