Accredited Drug Testing offers comprehensive hair follicle drug assessments in Nashville, Missouri. If you require a hair test for drugs or alcohol, Accredited Drug Testing is an expert in hair evaluations, and our facilities across all cities nationwide are equipped to conduct a hair test. Typically, 1.5 to 2 inches of hair from the crown or body may be used. Hair testing accommodates analyses for drugs, alcohol/ETG, or other tailored options.
Recently, the preference for drug testing has shifted towards hair follicle drug analyses. Employers, legal entities, and Substance Abuse experts more often dictate a hair test over a conventional urine examination. Hair follicle tests cater to employers with stringent no-drug policies, judicial systems, and probationers. The main advantage of a hair follicle test is its extended drug use detection window, reaching up to 90 days, conducted under observation, making it difficult to falsify. However, to determine recent drug use within 5 days, a urine test remains the most precise.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by capturing biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can offer a detection timeframe of up to around 3 months for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and easy to transport.
A 1.5-inch section of roughly 200 hairs (equivalent to a #2 pencil's thickness) nearest to the scalp provides 100mg of hair, the optimal amount for testing and validation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is suggested. We advise using a jeweler’s scale to measure the sample weight. If scalp hair is lacking, a similar quantity of body hair may be collected. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The four key steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial incorporation of a sample into the laboratory’s system. This procedure covers verifying that the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry missing from an electronic chain of custody system.
Screening comprises a preliminary rapid test for drug abuse. Screening is a budget-friendly method to dismiss drug use for most samples, but a positive screen requires confirmation to be court-admissible. Any samples showing presumptive positivity in Screening require further confirmation.
In instances of a presumptive positive during the Screening phase, additional hair is taken from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other methods (ex. urine or oral fluid), establishing hair drug screening as one of the most challenging methods to administer.
Confirmation of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if required. The full laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the test inspects the hair strand, not the follicle beneath the scalp.
