Accredited Drug Testing offers comprehensive hair follicle drug testing services in Woodburn, Iowa. If a hair drug or alcohol test is required, Accredited Drug Testing is an expert in hair testing, maintaining testing centers across the country capable of conducting hair tests. Typically, 1.5 to 2 inches of hair is required from the crown or other body areas. Hair tests assess for drugs, alcohol/ETG, or can be tailored for other options.
In recent times, hair follicle drug testing has become more common. Employers, courts, and Substance Abuse professionals increasingly favor hair tests over traditional urine tests. Employers with zero-tolerance policies, courts, and probationary individuals make consistent use of hair follicle tests. The test's advantage lies in its extended detection period, covering up to 90 days, ensuring observation during collection, and making cheating nearly impossible. However, for detecting drug use within the last 5 days, urine tests remain most precise.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug use by embedding biomarkers within its growing fibers. When clipped near the scalp, hair can reveal a usage history of approximately three months for both alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch section comprising roughly 200 hair strands (similar in size to a #2 pencil) from near the scalp yields 100mg, the optimal amount for both screening and confirmation. For EtG, tests exceeding 10 panels, or additional analyses, 150mg of hair is advised. We suggest weighing the hair sample with a jeweler's scale. In cases where scalp hair isn't available, an equivalent amount from body hair can be utilized. By "head hair," we mean exclusively scalp hair, while "body hair" encompasses facial, axillary, and other types.
Process Overview
There are four primary stages in lab processing a drug test result: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially entered into the laboratory system. This involves confirming the sample was properly sealed and transported, issuing a random LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody system.
Screening provides a preliminary assessment for substance abuse. While it is a cost-effective method to eliminate drug use in most samples, a positive result from Screening must be verified to be valid in court. Samples that test positive presumptively in Screening require further confirmation.
Should a sample show a presumptive positive in Screening, additional hair is extracted from the original sample for the Extraction process. Drugs are isolated from hair at lower concentrations than other methods (e.g., urine or saliva), highlighting the complexity of hair drug screening.
Confirmation of any Screening positive occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleaned before confirmation as required. The entire lab process, from Accessioning to Confirmation, is subject to review under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
