Recently, hair follicle drug assessments have gained traction for testing purposes. Many organizations, legal entities, and addiction treatment experts prefer hair testing over traditional urine analysis. Employers, courts, and those on probation often utilize hair tests due to their non-negotiable stance on drug use. The main advantage is prolonged drug detection (up to 90 days), conducted under strict protocols, making cheating nearly impossible, unlike urine tests, which excel in detecting recent substance use.

Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of drug and alcohol use by embedding biomarkers within the strands as they grow. Hair from the scalp can offer a detection period of up to 3 months. Collection of hair is straightforward, difficult to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (around the size of a #2 pencil) closest to the scalp yields 100mg, which is the optimal sample amount for screening and confirmation. For EtG, additional tests, or panels above 10, a sample of 150mg is suggested. We advise using a jeweler’s scale to weigh the sample. If scalp hair is not obtainable, an equivalent quantity of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (like facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is divided into Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary step of processing a sample into a lab's system. It ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fills in any data not included by an electronic chain of custody system.
Screening is an initial quick assessment for drugs of abuse. While Screening is an economical method to dismiss drug use in most samples, a positive result must be verified for legality. Any samples showing presumptive positivity in Screening necessitate further Confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at lower concentrations compared to other methods (such as urine or saliva), outlining why hair drug screening is the most intricate testing approach.
Confirmation of any screening positive is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation if necessary. The entire process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair distinction and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although often labeled as "hair follicle tests," the test examines the hair strand itself, not the follicle beneath the scalp.
