Accredited Drug Testing provides extensive hair follicle drug testing in Harrison, Michigan. If you require a drug or alcohol test using hair, we specialize in such testing and have facilities available in all cities across the nation to conduct a hair test. In most cases, you need 1.5 to 2 inches of hair from the scalp or body. Hair testing can be customized to detect drugs, alcohol/ETG, or other substances.
Recently, drug testing practices have increasingly adopted hair follicle drug tests. These tests are now preferred by numerous employers, judicial courts, and substance abuse specialists over traditional urine tests. Employers with zero-tolerance drug policies, judicial courts, and probationers commonly use hair tests. The key advantage of these tests is their extended drug use detection window, typically up to 90 days, and their supervised collection, which makes them hard to falsify. Nonetheless, urine tests remain the most precise for detecting drug use within a recent 5-day period.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the hair shaft as it grows, hair provides a historical record of substance use. When taken near the scalp, hair can yield a detection period of up to roughly 90 days for alcohol and other substances. The collection process is straightforward, altering the sample is relatively challenging, and the sample can be shipped with ease.
A 1.5-inch section containing about 200 hair strands (similar to the diameter of a #2 pencil) close to the scalp supplies 100mg of hair, the preferred amount for both screening and confirmation. For tests involving EtG or more than 10 drug panels, a 150mg specimen is advisable. It's recommended to weigh the sample using a jeweler’s scale. If no scalp hair is available, an equivalent quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other kinds (facial, axillary, etc.).
Process Overview
The laboratory procedure for drug test results consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step in processing a sample within a lab’s system. This step includes ensuring the sample's seal and shipment were intact, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry not provided through an electronic chain of custody.
Screening is a preliminary check for drug use. While it is an economical way to discount drug use in most specimens, any positive results from Screening must be verified to be valid in legal proceedings. Samples that test presumptively positive during Screening require follow-up confirmation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and made ready for Extraction. In this process, drugs are extracted from hair in significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing the most complex to perform.
Confirmation for any positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens are cleaned prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is conducted in adherence to both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation requirements.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. 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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
