Hair testing is widely regarded as an effective method for identifying drug and alcohol usage. Hair retains a lengthy record of alcohol and other substances by capturing biomarkers within the fibers of the growing hair shaft. Collected near the scalp, hair may offer a detection timeframe of up to roughly 90 days for alcohol and various drugs. It is easy to collect, relatively resistant to tampering, and convenient to ship.
A 1.5-inch portion comprising around 200 strands of hair (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional testing, and/or examinations beyond 10 panels, 150mg of the sample is advisable. Use of a jeweler’s scale is suggested for specimen measurement. If scalp hair cannot be obtained, a comparable amount of body hair is an alternative. By head hair, we mean scalp hair only. By body hair, we refer to all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of drug test outcomes includes the following four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into a laboratory’s system. It entails confirming that the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any needed data input absent from an electronic chain of custody system.
Screening is an initial swift assessment for drugs of abuse. While it is a cost-efficient approach to exclude drug consumption in most samples, a positive screening must be verified to be admissible in legal proceedings. Presumptively positive samples in Screening necessitate a secondary confirmation.
If a sample tests presumptively positive during Screening, more hair is extracted from the original sample and prepared for Extraction. In this stage, drugs are withdrawn from hair at significantly lower levels than in other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging methodology to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as required. The whole laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair categorization and accreditation to ISO / IEC 17025 standards.

Note: Even though commonly called "hair follicle tests", the analysis targets the hair shaft and not the hair follicle beneath the scalp.
