The trend in drug testing methods has increasingly shifted towards hair follicle tests in recent years. A growing number of employers, judicial systems, and Substance Abuse specialists now prefer hair drug tests over the traditional urine tests. These tests are favored by employers with strict anti-drug policies, legal systems, and probation management due to their extended detection period, which usually spans up to 90 days. They are collected under supervised conditions and offer a high resistance to manipulation, though urine tests are still preferred for pinpointing use in the last 5 days.

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a history of substance use by capturing biomarkers in the fibers as the hair grows. When taken near the scalp, a hair sample can reveal drug and alcohol use over roughly three months. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5 inches of about 200 hair strands (approximately the diameter of a #2 pencil) adjacent to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for specimen weighing. If scalp hair isn't available, the equivalent amount of body hair can be used. When referring to head hair, we mean scalp hair only, whereas all other hair forms, like facial or axillary, are considered body hair.
Process Overview
The primary steps in laboratory drug test analysis are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in processing a sample within a lab system. It ensures the sample's seal and shipment integrity, assigns a LAN (Laboratory Accessioning Number), and completes any remaining data entry not covered by an e-chain of custody.
Screening is a preliminary swift assessment for drug presence. While Screening efficiently negates drug use in most cases, a positive outcome requires validation for legal acceptance. All presumptive positive samples in Screening necessitate a follow-up confirmation.
Should a sample test positive in Screening, additional hair is extracted and prepped for Extraction. Drugs are retrieved from hair at considerably lower levels than in urine or saliva tests, making hair screening a challenging procedure.
Positive results in Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS, with presumptive positive samples washed beforehand if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) standards and ISO / IEC 17025 accreditation.
