Accredited Drug Testing provides comprehensive hair follicle drug tests in Winston, Missouri. If a hair drug or alcohol test is needed, we specialize in hair analysis with testing centers across cities in all states to conduct hair tests. Generally, 1.5 to 2 inches of hair from the scalp or body can be tested. Hair analysis can screen for drugs, alcohol/ETG, or other personalized options.
Lately, drug testing methods often include hair follicle analysis. Employers, courts, and Substance Abuse professionals usually prefer hair testing to traditional urine, making it essential for zero-tolerance employers, courts, and those on probation. Its major benefit comes from the longer detection duration, typically up to 90 days, with observed collection ensuring integrity, while urine tests remain best for recent usage within the last 5 days.

Hair analysis is increasingly recognized as a robust method for detecting substance use, including alcohol. Hair strands capture a historical record of substances by embedding biomarkers in the hair's fibers as it grows. When clipped close to the scalp, hair offers a detection period of up to about three months for substance use. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch hair sample of roughly 200 strands (comparable in size to a #2 pencil) close to the scalp provides 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. It's best to weigh the sample on a jeweler’s scale. In cases where scalp hair is not available, an equivalent quantity of body hair may be used. "Head hair" exclusively pertains to scalp hair, while "body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
The drug test result process in a laboratory entails four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory step, where the sample is logged into the lab's system. This process ensures the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and handles any supplementary data entry not included in an electronic chain of custody.
Screening performs an initial evaluation for drugs of abuse. Though Screening serves as a cost-efficient method to rule out drug use in most cases, confirming a positive screen is necessary for legal proceedings. Any samples that test presumptively positive in Screening must undergo additional confirmation.
Should a sample show a presumptive positive outcome at the Screening phase, further hair is taken from the initial sample and readied for Extraction. Here, drugs are withdrawn from hair at much lower concentrations compared to other methods, such as urine or oral fluid, making hair drug screening one of the most complex methodologies to execute.
Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation if needed. From Accessioning to Confirmation, the entire lab process is overseen according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests", the analysis actually focuses on the hair strand itself, not the follicle beneath the scalp.
