Accredited Drug Testing offers comprehensive hair follicle drug assessments in Castle Rock, Wisconsin. For those requiring a hair drug or alcohol analysis, our expertise in hair testing is unmatched. We host testing facilities across all major cities nationwide capable of conducting precise hair tests. It is generally necessary to have 1.5 to 2 inches of hair on the scalp, though body hair can be used in most instances. Hair examinations can be tailored to detect drugs, alcohol/ETG, or other specific substances.
Lately, drug testing processes have increasingly incorporated hair follicle examinations. Numerous employers, judicial systems, and Substance Abuse specialists prefer a hair drug test over a standard urine analysis. These examinations cater to employers with strict drug-use policies, legal systems, and probation monitoring. Hair follicle tests offer a distinct advantage due to a longer detection range, typically up to 90 days, with direct observation during collection, making it nearly foolproof. Nevertheless, to assess drug use within the preceding five days, urine tests remain the most reliable method.

Hair testing is recognized as an effective method for identifying alcohol and drug usage. The fibers in a strand of hair capture biomarkers, offering a long-term record of alcohol and drug presence. When collected near the scalp, hair testing can detect drug use over a period extending up to approximately three months. It's easy to collect hair samples, hard to tamper with them, and the shipping process is straightforward.
A 1.5-inch section with approximately 200 hair strands (equivalent to the thickness of a #2 pencil) taken from near the scalp provides 100mg, which is the optimal sample for both initial and confirmation tests. For EtG, add-ons, and/or tests exceeding 10 panels, it's advised to use 150mg of the sample. Using a jeweler’s scale for weighing the hair specimen is advised. In the absence of scalp hair, the same amount of body hair may be utilized. In this context, head hair refers exclusively to scalp hair, whereas body hair encompasses all other types, such as facial or axillary hair.
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing within a lab's system. This step ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and adds any supplementary data not available through an electronic chain of custody system.
Screening is a preliminary, rapid test for substance abuse. While this step is cost-efficient for excluding drug use in most samples, any positive result requires confirmation to be court-admissible. Any sample yielding a potential positive result during Screening must undergo further confirmation.
If the Screening stage implies a positive result, additional hair is taken from the sample for the Extraction process. At this stage, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which underscores the complexity of hair drug screening methodology.
The Confirmation of any positive screening outcome is executed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All provisional positive samples are washed before confirmation, as needed. The complete lab process from Accessioning to Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
