The use of hair analysis has become recognized as an effective method for identifying the consumption of drugs and alcohol. Hair captures a long-term record of substance use by embedding biomarkers within the fibers as the hair grows. Collecting hair near the scalp can offer up to a three-month detection period for alcohol and other drugs. It's easy to collect, hard to tamper with, and straightforward to ship.
A 1.5-inch hair sample consisting of roughly 200 strands (comparable to the thickness of a #2 pencil) from the scalp yields 100mg of hair, which is optimal for both screening and verification. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not available, an equivalent amount of body hair may be utilized. When discussing head hair, we exclusively mean scalp hair, whereas body hair includes all other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's system. This process ensures the sample is properly sealed and couriered, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not covered by an electronic chain of custody.
Screening provides an initial assessment for substances of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive outcome needs confirmation to be court-admissible. Any samples deemed presumptively positive during Screening need further confirmation.
Should a sample indicate presumptive positivity in Screening, additional hair is selected from the initial collection for Extraction. In this step, drugs are separated from the hair at a notably lower concentration than other techniques (such as urine or saliva), underscoring why hair drug testing is the most complex method to execute.
Confirming a positive result from the screening involves testing via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples identified as presumptive positives are washed beforehand for Confirmation. The complete lab process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and is accredited to the ISO / IEC 17025 standards.
