Accredited Drug Testing offers comprehensive hair follicle drug testing services in Castle Point, Missouri. For those needing drug or alcohol testing, we specialize in hair testing with centers available in cities across the nation. Typically, 1.5 to 2 inches of hair on the head is required, though body hair may suffice. Hair tests can be utilized for drugs, alcohol/ETG, or other specific testing needs.
In recent times, hair follicle drug tests have become more prevalent in drug testing methods. Employers, courts, and substance abuse experts often opt for hair drug tests rather than urine tests. These tests are preferred by those enforcing strict no-drug policies, court reviews, or for probation monitoring. The advantage lies in their lengthy detection window for drug use, up to 90 days, and the difficulty in manipulating the test. However, for recent drug use detection within 5 days, urine tests remain the more precise option.

Hair drug testing is recognized as a robust method for uncovering drug and alcohol consumption. Hair captures a comprehensive history of drug and alcohol use by embedding biomarkers within the strands as they grow. By acquiring samples close to the scalp, a detection period of up to three months for drugs and alcohol can be achieved. The collection of hair is straightforward, challenging to tamper with, and convenient for shipping.
Collecting a 1.5-inch sample comprising approximately 200 hair strands (equivalent to a #2 pencil's thickness) from near the scalp yields 100mg of hair, which is optimal for screening and verification. In the case of EtG, additional tests, or analysis exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the specimen using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair may be utilized. When mentioning head hair, we mean only scalp hair. Body hair refers to other hair types (facial, underarm, etc.).
Process Overview
There are four primary stages involved in processing a test result in the laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into a laboratory's system. This step involves confirming the sample's proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drugs of abuse. While it is a cost-effective method for excluding drug presence in many samples, a positive result in screening requires confirmation for legal admissibility. Samples that appear positive initially must undergo a secondary verification.
If a sample tests presumably positive during the Screening phase, more hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are retrieved from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of any positive result from screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as required. The full laboratory process, from Accessioning to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
