Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. The hair strand's growth fibers capture biomarkers, thus providing a long-lasting record of substance use. When collected near the scalp, it offers a detection timeline of up to about three months for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and easy to mail.
Securing a 1.5-inch piece with roughly 200 hair strands (comparable to a #2 pencil's thickness) from the scalp yields 100mg, which is perfect for assessment and validation. For EtG, additional analyses, and tests exceeding 10 panels, 150mg is advisable. The sample's weight should ideally be confirmed using a jeweler’s scale. Should scalp hair be missing, an equivalent quantity of body hair is an alternative. Scalp hair specifically denotes head hair, while body hair encompasses all other types (e.g., facial, underarm).
Procedure Outline
The key procedures for analyzing a drug test specimen in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into a laboratory’s processing system. This comprises ensuring proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and inputting any necessary data absent in an electronic chain of custody framework.
Screening consists of a preliminary brief evaluation for substance abuse. Although Screening is economical for ruling out drug intake in most samples, any positive screening must be confirmed to be considered valid in a legal setting. Thus, samples that test presumptively positive during Screening require subsequent confirmation.
Should a sample indicate positivity in Screening, additional hair is selected from the original sample for Extraction. During this stage, substances are retrieved from hair at markedly reduced concentrations than alternative methodologies (such as urine or oral fluid), making hair analysis the most challenging methodology to execute.
Verification of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleansed before verification when necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated per the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Drawbacks:
Clarification: Though frequently termed "hair follicle tests", the analysis is conducted on the strand of hair, not on the follicle beneath the scalp.
