Accredited Drug Testing provides comprehensive hair follicle drug testing services in Kimberling City, Missouri. If you're in need of drug or alcohol testing through hair samples, we are the experts in the field, with testing centers spread across cities nationwide ready to conduct hair tests. For testing, a hair length of 1.5 to 2 inches from the crown of the head or body suffices in most scenarios. Hair analysis can detect drugs, alcohol/ETG, as well as other tailored testing options.
Recently, drug testing methods have increasingly incorporated hair follicle drug tests. Many employers, courts, and substance abuse experts now favor hair follicle tests over traditional urine tests. These tests are especially used by zero-tolerance employers, judicial systems, and probation officers, offering a longer detection window of up to 90 days due to the observed collection process, making them almost impossible to tamper with. Nevertheless, urine tests remain the most accurate choice for detecting recent drug use within the past five days.

Hair examination is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substances by embedding biomarkers within its fibers during growth. When taken near the scalp, hair offers a detection period of up to roughly three months for substances. Collecting hair is straightforward, not easily altered, and convenient for transportation.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) from the scalp, provides 100mg of hair, which is the prime amount for both screening and verification. For EtG, additional analyses, and/or screenings above 10 panels, a 150mg specimen is advised. We suggest weighing the sample with a jeweler's scale. If scalp hair is not available, a similar quantity of body hair may be used. When 'head hair' is mentioned, it refers solely to scalp hair. 'Body hair' encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab system, including verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not covered by an electronic custody system.
Screening involves a preliminary swift evaluation for drugs. While Screening is cost-efficient for ruling out drug use in most cases, a positive result requires confirmation for court validity. Samples that test presumptively positive during Screening need a subsequent confirmation.
Should a sample test presumptively positive during Screening, additional hair is taken from the original sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than other means (e.g., urine or mouth fluid), which renders hair drug analysis the most challenging to execute.
The Confirmation of positive Screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing positive are washed as necessary before Confirmation. The full laboratory process, from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests," the test actually examines the hair strand, not the follicle beneath the scalp.
