If hair or alcohol testing is needed, Accredited Drug Testing is proficient in hair tests, and our centers nationwide, including every city, are equipped to perform hair tests.

Recently, drug testing methods increasingly incorporate hair follicle tests. Many employers, courts, and substance abuse specialists favor hair drug tests over standard urine tests. These are essential for employers upholding zero-tolerance policies, court directives, and probation circumstances. The main advantage of hair testing is the extended detection window, covering up to 90 days, with an observed collection process, rendering them virtually foolproof. Urine tests, however, remain accurate for detecting drug use within five days.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a lasting record of alcohol and drug usage by capturing biomarkers in the fibers of the growing strand. When obtained near the scalp, hair can reveal substance use over a period of up to three months. This method is straightforward to collect, challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, encompassing approximately 200 hair strands (equivalent to a #2 pencil's diameter) from the scalp provides 100mg, which is ideal for testing. For EtG, additional testing, or assessments exceeding 10 panels, a 150mg sample is suggested. It is advised to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equal quantity of body hair can be used. "Head hair" refers purely to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The four principal steps involved in the laboratory analysis of a drug test sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial processing phase of a sample into a lab’s system, ensuring the sample is sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and concluding any additional data entry not handled by an electronic chain of custody system.
Screening serves as a preliminary assessment for drugs of abuse. While it is a cost-effective preliminary method to exclude drug presence in many specimens, a positive screening must be substantiated to be legally valid. Any presumptively positive samples in Screening necessitate further confirmation.
In testing presumptively positive samples, additional hair is gathered from the original sample for the Extraction process. Here, drug compounds are extracted from hair at a significantly lower concentration compared to methods like urine or oral fluid testing, contributing to the high complexity of hair drug screening.
Verification of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens undergo washing prior to confirmation where required. The comprehensive laboratory procedure from Accessioning to Confirmation is appraised under both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 criteria.
