Accredited Drug Testing provides comprehensive hair follicle drug testing services in Dewhurst, Wisconsin. For drug or alcohol testing through hair, Accredited Drug Testing is a specialist in this field with testing locations nationwide. A hair sample of 1.5 to 2 inches from your head or body can typically be used. Hair analysis services are available for drug detection, alcohol/ETG, and other specialized options.
Recently, hair follicle drug tests have increasingly become the method of choice for drug testing. Employers, legal bodies, and Substance Abuse experts often prefer hair tests over traditional urine testing. This is largely due to hair follicle tests offering a longer drug detection window—up to 90 days—whilst being difficult to tamper with. For detecting recent drug use (within 5 days), however, urine tests remain most accurate.

Hair testing is now recognized as a robust means for identifying drug and alcohol consumption. Hair captures a prolonged history of such substances by securing biomarkers within the strands of hair as they grow. When gathered close to the scalp, hair offers an approximate 3-month detection period for both alcohol and drugs. Hair collections are straightforward, somewhat resistant to tampering, and easily transportable.
A sample of 1.5 inches comprising about 200 hair strands (equivalent in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for screenings and confirmatory tests. For EtG, additional tests, and/or panels greater than 10, a specimen of 150mg is advised. It is suggested to measure the specimen using a jeweler's scale. Should scalp hair not be available, an equivalent amount of body hair is a viable alternative. When mentioning head hair, this refers specifically to scalp hair. Body hair encompasses all other hair types (including facial hair, axillary hair, etc.).
Process Overview
There are four primary phases in the laboratory handling of a drug testing result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into the laboratory's system. This step involves verifying the sample's seal and correct shipment, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any extra data entry not handled by an electronic chain of custody.
Screening consists of a rapid initial assessment for substances being abused. While Screening serves as an economical method to exclude drug use in most samples, any positive outcome requires confirmation to become admissible in a legal setting. All samples that show a presumptive positive in Screening necessitate further verification.
Should a sample display a presumptive positive outcome in Screening, additional hair is taken from the initial sample to prepare for Extraction. At this phase, drugs are removed from hair at a concentration much lower than other approaches (such as urine or oral fluid), making hair drug testing the most challenging method to implement.
Confirming any positive screening result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are washed as needed prior to confirmation. The full laboratory processing, from Accessioning through Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation standards.
