Hair follicle testing is recognized as an effective instrument for identifying the use of substances like drugs and alcohol. Hair captures a prolonged record of drug and alcohol presence by trapping specific markers within the threads of the growing hair. When hair is obtained near the scalp, it offers an approximate 3-month detection period for substances. It’s easy to obtain, challenging to tamper, and simple to dispatch.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (about the thickness of a #2 pencil) near the scalp, yields 100mg, which is ideal for analysis and verification. For EtG extensions and tests exceeding 10 panels, a 150mg amount is ideal. It is advised to measure the sample with a jeweler’s scale. If scalp hair isn’t accessible, a comparable amount of body hair can be gathered. When mentioning head hair, we imply scalp hair only, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of drug test results involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, initial processing of the sample into the lab's system occurs. This step ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry not covered by an electronic chain of custody system.
Screening conducts a preliminary examination for substance use. Though Screening effectively rules out drug usage in most cases economically, any preliminary positive results necessitate confirmation to stand in a legal context. All presumptive positives identified in Screening require further verification.
If preliminary results in Screening indicate positivity, additional hair is taken from the original sample and set for Extraction. In Extraction, drugs are drawn from hair at significantly lower levels compared to other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.
Confirmation follows any positive Screening through methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as positive are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes review under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
