Many businesses, judicial entities, and Substance Abuse experts favor this approach over the conventional urine test. Employers enforcing no-drug policies, legal bodies, and individuals on probation utilize hair follicle drug tests due to a longer detection period—usually up to 90 days—and an observed collection process that is hard to circumvent. Urine tests, however, remain the most precise for detecting recent drug use within the last 5 days.

Hair screening is now acknowledged as an effective method for identifying drug and alcohol consumption. Hair strands offer an extended history of substance use by encapsulating biomarkers within their fibers as they grow. When collected near the scalp, these samples can reveal alcohol and drug usage over a period of approximately three months. Hair is easy to gather, difficult to tamper with, and straightforward to transport.
A 1.5-inch section comprising roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, additional tests, and/or those involving more than 10 panels, 150mg of the sample is advisable. The specimen's weight could be checked with a jeweler’s scale. If scalp hair isn't available, a similar volume of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The core stages in laboratory drug test result processing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary process of integrating a sample into the lab's system. This step includes confirming appropriate sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing any outstanding data entry if an electronic chain of custody system was not used.
Screening entails an initial prompt examination for drug abuse. Screening is cost-effective for excluding drug presence in the majority of samples; however, a positive result requires further confirmation to be court-valid. Any samples that test positive during Screening need additional confirmation.
If a sample is suspected positive during the Screening stage, extra hair is extracted from the original sample for Preparation. In this phase, drugs are isolated from hair at considerably lower concentrations than with other methodologies (e.g., urine or oral fluid), which renders hair drug screening the most challenging method to execute.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples suspected to be positive are cleansed prior to confirmation as required. The complete laboratory procedure from Accessioning through to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and conforms to ISO / IEC 17025 standards.
