In Douds, Iowa, Accredited Drug Testing offers comprehensive hair follicle drug tests.

A hair length of 1.5 to 2 inches from the crown or body suffices for most cases. Capable of detecting drugs, alcohol/ETG, and offering other custom options.
Recent trends show a growing reliance on hair follicle drug tests for substance screening. Many employers, judicial entities, and substance abuse specialists prefer this to urine tests. Whether used by zero-tolerance employers or probation mandates, these tests offer a longer detection window, typically up to 90 days, and near immunity to falsification. Despite this, urine tests hold accuracy for recent (within 5-day) drug use.
* 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 examinations are increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a comprehensive record of alcohol and drugs by capturing biomarkers within the structure of the growing hair strand. When sourced near the scalp, hair offers an approximate 3-month detection span for alcohol and other drugs. Its collection is straightforward, manipulation is relatively difficult, and it is easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to measure the specimen is recommended. If scalp hair is unavailable, a comparable quantity of body hair can be collected. Head hair exclusively refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a laboratory’s system. This step ensures the sample's seal and shipment integrity, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any data entry lacking in an electronic chain of custody system.
Screening consists of a preliminary evaluation for substance abuse. Although Screening efficiently rules out drug usage for most samples, a positive result requires confirmation for court validity. Samples showing presumptive positives in Screening must undergo further verification.
Should a sample show a presumptive positive in Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from the hair at much lower concentrations than in other methods (e.g., urine or oral fluid), illustrating why hair drug screenings are among the most challenging methodologies to execute.
Confirmation of any positive Screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples with presumptive positives are cleansed as necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair authorization and the ISO / IEC 17025 accreditation standards.
