Accredited Drug Testing provides thorough hair follicle drug testing services in Hopkins, Missouri. If you require a hair drug or alcohol screening, we are specialists in hair testing and have centers in cities across the nation that can conduct these tests. Generally, 1.5 to 2 inches of hair from the scalp or body can be used. Hair testing can identify drugs, alcohol/ETG, and other specialized options.
In recent years, hair follicle drug testing has become a more common procedure for detecting drug use. This method is now preferred by many employers, courts, and substance abuse professionals over typical urine tests. Employers, especially those with zero-tolerance policies, courts, and probationary programs trust hair tests due to their extended detection period—up to 90 days—and near impossibility to tamper with. For screening drug use within the last 5 days, urine tests remain highly accurate.

Hair testing is recognized as a highly effective method for identifying drug and alcohol consumption. Hair can capture biomarkers in the fibers of the growing strand, offering a long-term history of substance use. When samples are obtained near the scalp, they can yield a detection window of approximately 3 months for alcohol and other drugs. Collecting hair is straightforward, somewhat challenging to tamper with, and easy to transport.
A segment measuring 1.5 inches, consisting of roughly 200 hairs (approximately the width of a #2 pencil) nearest the scalp, will yield 100mg, considered optimal for both screening and confirmation processes. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of the sample is suggested. We recommend the specimen be weighed using a jeweler’s scale. If head hair is unavailable, an equivalent quantity of body hair can be gathered. When discussing head hair, it refers exclusively to scalp hair. "Body hair" refers to all other hair categories, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the first stage of processing a sample within the lab's system. This entails verifying the sample's sealing and shipping integrity, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not captured by an electronic chain of custody protocol.
Screening provides an initial swift assessment for drugs of abuse. While Screening is economical for dismissing drug use in most samples, a positive result requires confirmation to be legally valid. All samples presumed positive during Screening necessitate a secondary confirmation.
If a sample shows a presumptive positive at the Screening phase, additional hair is extracted from the original sample for the Extraction process. Drugs are extracted at notably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Confirmation of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as required. The entire laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and accreditation according to ISO / IEC 17025 standards.
