Accredited Drug Testing provides comprehensive hair follicle drug testing services in Chesterfield, Illinois. Whether it's for alcohol or drug tests, we excel in hair testing with centers situated in cities across the nation, ready to conduct these tests. Generally, 1.5 to 2 inches of hair from the crown or body is needed. Hair testing can accurately assess the presence of drugs, alcohol/ETG, or offer other tailored testing solutions.
The preference for hair follicle drug tests has grown over recent years, replacing traditional urine tests for many employers, courts, and Substance Abuse experts. Institutions with zero-tolerance drug policies, including courts and probation programs, value the extended detection timeframe of hair tests, which can track substance use up to 90 days, ensuring reliable testing collected under observation, and making cheating virtually impossible. For recent drug use (last 5 days), urine tests remain more precise.

Hair testing is increasingly recognized as an effective means to detect drug and alcohol use. Hair captures a historical record of these substances by embedding biomarkers in the keratin fibers of hair as it grows. When cut close to the scalp, a hair sample can reflect substance use over an approximately three-month span. Hair collection is straightforward, resistant to tampering, and convenient for transport.
A sample measuring 1.5 inches with around 200 strands from the scalp (roughly equivalent to a #2 pencil's thickness) will provide 100mg, which is the optimal quantity for analysis and verification. For tests involving EtG, additional requirements, or more than 10 panels, 150mg of the sample is preferred. We recommend assessing the sample weight using a jeweler's scale. If head hair cannot be obtained, an equivalent amount of body hair can be collected. Head hair specifically refers to scalp hair, while body hair includes all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample enters the laboratory system. This step involves checking that the sample is sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody.
Screening entails a preliminary test for potential drug use. While it's a cost-efficient method to exclude drug presence for most samples, any positive result from Screening must be confirmed for legal acceptability. Samples that show a presumptive positive in Screening proceed to a subsequent verification step.
A presumptively positive Screening result leads to additional hair being prepared from the original sample for Extraction. During Extraction, drugs are removed from hair at a much lower concentration than via other techniques (like urine or oral fluid), making hair drug screening the most challenging technique to execute.
Confirmation of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as necessary. The complete process from Accessioning to Confirmation is conducted under the guidelines of both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation.
