Hair testing emerges as a robust method for identifying drug and alcohol usage. Hair captures a prolonged record of alcohol and drugs by securing biomarkers within the strands of the growing hair. When collected near the scalp, hair reveals a detection period of up to around 90 days for alcohol and drugs. Hair collection is straightforward, resistant to tampering, and simple to transport.
A 1.5-inch hair sample (about 200 strands or the diameter of a #2 pencil) near the scalp yields 100mg, the preferred amount for both screening and confirmation testing. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not attainable, a comparable volume of body hair can be used. "Head hair" implies scalp hair exclusively. "Body hair" pertains to all other varieties (facial, underarm, etc.).
Process Overview
The laboratory procedure for processing a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial input of a specimen into a lab’s system, including the verification of proper sample sealing and shipment, the assignment of a random LAN (Laboratory Accessioning Number), and the completion of any further data entry absent from an electronic chain of custody.
Screening provides an initial rapid evaluation for drug presence. Although it is an economical approach to exclude drug use for most samples, a positive screen mandates confirmation for legal admissibility. Presumptive positives at the Screening phase require a follow-up confirmation.
In cases of a presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Drugs are withdrawn from hair at significantly lower concentrations than in other methods (e.g., urine or saliva), highlighting the complexity of hair drug screening.
Confirmation of any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washing before confirmation. The comprehensive laboratory sequence from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and is accredited according to ISO / IEC 17025 standards.
