Accredited Drug Testing offers comprehensive hair follicle drug testing services in Green Castle, Missouri. If a hair or alcohol test is needed, Accredited Drug Testing excels in this area with testing locations across the country. Typically, 1.5 to 2 inches of hair from the head or body are required. Hair tests are suitable for detecting drugs, alcohol/ETG, or other specific hair test options.
In recent times, hair follicle drug testing has gained traction over traditional methods. Employers, judicial systems, and substance abuse experts opt for hair tests over standard urine samples. This method is favored by organizations with strict no-drug policies, legal entities, and probation officers. Hair tests have a longer detection span, up to 90 days, and are observed when collected, making them hard to compromise. Yet, for drug use within the prior 5 days, urine tests remain precise.

The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers in the hair strand's fibers as it grows. When collected near the scalp, this method can detect alcohol and other drugs within roughly a 3-month period. Collecting hair is straightforward, somewhat tamper-resistant, and easy to transport.
A sample of 1.5 inches, roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advised. Using a jeweler’s scale to weigh the specimen is advisable. Should scalp hair be unavailable, an equivalent amount of body hair can be used. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the laboratory’s system. This step checks that the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. While it is a cost-efficient way to exclude drug usage in most cases, a positive screen must be confirmed to be valid in legal settings. Any samples that are presumptively positive during Screening require further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology.
Confirmation for any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. The entire laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
