Accredited Drug Testing offers extensive hair follicle drug screening in Arnold, Missouri. For those in need of a hair or alcohol test, we're experts in hair analysis, with facilities available nationwide. Typically, 1.5 to 2 inches of hair is required from the head or body. Hair testing enables analysis for substances, alcohol/ETG, or other tailored testing choices.
Hair follicle drug tests have gained popularity in recent years for substance detection. Increasingly, employers, legal courts, and substance abuse specialists favor hair tests over urine tests. These tests are essential for workplaces with zero-tolerance policies, judiciary systems, and probation cases. A significant advantage is the extended detection period for substances, which can reach up to 90 days, collected under supervision, making tampering difficult. However, for recent substance use within 5 days, urine tests remain the most precise choice.

Hair follicle evaluations have emerged as a robust means for detecting substance and alcohol consumption. With the ability to encapsulate biomarkers within the fibers of a growing hair strand, hair offers an extended history of alcohol and drug use. When procured near the scalp, hair can offer an approximate detection period of up to 3 months for alcohol and various substances. Hair collection is straightforward, fairly resistant to tampering, and easy for transport.
A sample of 1.5 inches consisting of about 200 strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair—this is the optimal sample for screening and verification. For EtG, additional tests, and/or tests surpassing 10 panels, 150mg of the specimen is advisable. We suggest using a jeweler’s scale for weighing the specimen. Should scalp hair be inaccessible, an equivalent quantity of body hair may be collected. Head hair signifies scalp hair exclusively. Body hair pertains to other types (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial phase of processing a sample within a laboratory’s system. It involves verifying the secure sealing and correctly shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing extra data entry absent in an electronic chain of custody system.
Screening involves a preliminary quick assessment for substances of abuse. Though Screening is a cost-efficient method to assess drug usage across most samples, confirmation is needed for a positive screen to be acceptable in legal contexts. Presumptive positive samples in Screening require further confirmation.
Should a sample show a presumptive positive in the Screening stage, more hair is taken from the original specimen for Extraction. Drugs are extracted from hair at notably lower concentrations compared to other methodologies (ex. urine or oral fluid), which renders hair drug screening as one of the most challenging methodologies to execute.
Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo a wash prior to confirmation as necessary. The entire laboratory progression from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.
