Hair analysis is increasingly viewed as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the growing strand. When hair is taken close to the scalp, it can offer an approximate 3-month detection span for substances. Hair is easy to collect, somewhat challenging to tamper with, and simple to ship.
A sample measuring 1.5 inches with roughly 200 hair strands (similar to a #2 pencil in size) closest to the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, collecting 150mg of the specimen is advisable. It is advised to use a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar quantity of body hair may be used. When speaking about head hair, we mean only scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a specimen within a lab’s system. This process involves confirming the proper sealing and shipment of the sample, allotting a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary fast check for substances. While this is a cost-effective means to negate drug use in the majority of instances, a positive result must be verified for legal admissibility. Any samples that test presumptively positive in Screening require additional confirmation.
If a specimen tests presumptively positive during Screening, more hair is taken from the original sample for Extraction. This process extracts substances from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug analysis the most challenging method to execute.
The Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo a wash before confirmation if necessary. The entire lab operation from Accessioning to Confirmation is scrutinized under the guidelines of both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
