In Princeton, Michigan, Accredited Drug Testing offers comprehensive hair follicle drug testing. If you're in need of hair drug or alcohol testing, we provide specialized services with facilities available across all cities in the nation. Typically, possessing 1.5 to 2 inches of hair on the head is required, but body hair can also be utilized as needed. Hair testing is available for drugs, alcohol/ETG, as well as varied customizable testing kits.
Over recent years, the hair follicle drug test has become an increasingly used method for drug screening. Many companies, judiciary entities, and addiction specialists are opting for hair drug tests over traditional urine testing. They are favored by employers with strict drug-free mandates, courts, and individuals on probation. The chief advantage of this test is its extended detection window, usually effective for up to 90 days, collected under supervision, making tampering nearly impossible. Nevertheless, for substances used within the past 5 days, urine testing remains the most precise method.

Recognized as a significant tool, hair testing is utilized to detect substance use, capturing a comprehensive record of drug and alcohol consumption by embedding biomarkers in the hair as it grows. When samples are obtained near the scalp, hair offers a detection window of roughly 3 months for various substances. Collection is straightforward, tampering is challenging, and transportation is easy.
A hair sample measuring 1.5 inches with approximately 200 strands (comparable to the width of a #2 pencil) from the closest point to the scalp yields about 100mg, which is the optimal sample size for assessment and validation. However, for EtG, additional tests, or those exceeding 10 panels, a specimen of 150mg is advisable. It is best to weigh the hair sample using a jeweler's scale. In cases where scalp hair is not available, an equivalent amount of body hair can be used. The term "head hair" specifically refers to scalp hair, while "body hair" pertains to all other types (such as facial, axillary, etc.).
Process Overview
The drug testing result process comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's system, ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that is not already part of an electronic chain of custody system.
Screening consists of an initial evaluation to detect abusive substances. While it is an economical method to rule out drug use in the majority of samples, a positive screening outcome necessitates confirmation for legal acceptance. Samples with preliminary positive results in Screening require a secondary Confirmation step.
For samples indicating a positive result in Screening, additional hair is utilized from the initial sample for the Extraction stage. Here, the substance extraction from hair occurs at much lower concentrations than other methods (like urine or oral fluid), thereby making hair drug testing the most complex method to perform.
Confirmation for any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples with presumption of positive results are washed if necessary. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the College of American Pathologists (CAP) Hair designation and in accordance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Referred to generally as "hair follicle tests", the analysis targets the hair strand itself and not the follicle beneath the scalp.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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.
