Accredited Drug Testing provides thorough hair follicle drug exams in Winchester, Missouri. For those in need of hair drug or alcohol screening, Accredited Drug Testing is a leader in hair testing, offering facilities nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the scalp or body is needed. These tests can assess drug, alcohol/ETG, or other tailored hair sampling options.
Recently, hair follicle drug tests have become a more common method for screening substance use. Many employers, judicial systems, and addiction specialists prefer hair tests over the conventional urine method. Hair follicle tests assist in enforcing zero-tolerance policies by employers, judicial orders, and probation monitoring. A key advantage includes a longer detection span of up to 90 days, making it difficult to tamper with. However, for drug use detected within 5 days, urine testing remains most precise.

Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair traps biomarkers along the hair strand, providing a long-term record of substance use. When obtained close to the scalp, hair samples offer a drug and alcohol detection window of up to roughly three months. Hair collection is straightforward, fairly resistant to tampering, and easy to transport.
To obtain the ideal sample for screening and confirmation, a 1.5-inch sample of around 200 hair strands (about the thickness of a #2 pencil) closest to the scalp is needed, providing 100mg of hair. For EtG, additional tests, or assays exceeding ten panels, 150mg of hair is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be used. Reference to head hair is solely about scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory system. This step involves confirming the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening is a preliminary examination of samples for drug abuse. While Screening is a cost-efficient way to exclude drug presence in most samples, a positive Screening result must be confirmed for it to be admissible in legal proceedings. Any sample with a potentially positive result during Screening requires further confirmation.
Should a sample show a potential positive during Screening, more of the specimen is extracted for further analysis. This Extraction phase involves obtaining drugs from hair at much lower concentrations compared to other techniques (such as urine or oral fluid), highlighting the challenge of hair drug screening.
Confirmation of a positive Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples presumed positive are washed, as necessary. Every stage, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
