Accredited Drug Testing offers comprehensive hair follicle drug testing services in California, Pennsylvania. If a drug or alcohol hair test is needed, our expertise lies in hair testing, with centers nationwide ready to perform the test. Typically, 1.5 to 2 inches of head or body hair is necessary. Hair testing can detect drugs, alcohol/ETG, or other customized substances.
Recently, the method for drug testing has increasingly favored hair follicle tests. Employers, courts, and substance abuse experts often choose hair tests over urine. Hair follicle tests are preferred by employers with strict drug policies, courts, and those on probation. The main advantage is a longer detection period, up to 90 days, conducted under observation, and almost impossible to tamper with. However, for detecting recent drug use within five days, urine tests remain most accurate.

Hair evaluations are recognized as an effective mechanism for identifying drug and alcohol consumption. The hair offers an extensive chronology of alcohol and drug presence by capturing biomarkers within the fibers of the growing strand. When taken near the scalp, hair can reveal up to a roughly 90-day detection span for alcohol and drugs. Hair is straightforward to collect, not easily tampered with, and convenient to transport.
A segment measuring 1.5 inches containing around 200 strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimum amount for testing and confirmation. For EtG, additional tests, and/or evaluations exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale for specimen weighing. If no scalp hair is present, a similar quantity of body hair may be used. When referencing head hair, we mean scalp hair exclusively. Body hair entails all other hair types (facial, axillary, etc.).
Process Outline
The four pivotal procedures in the lab analysis for a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's framework. This process includes validating that the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not covered by an electronic chain of custody protocol.
Screening entails a preliminary swift evaluation for drugs of misuse. Though Screening provides a financially efficient strategy to rule out drug usage in most tests, a positive result requires verification to be legally acceptable. Any samples that yield a presumptive positive in Screening necessitate further confirmation.
If a sample impresses as positive during the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. At this juncture, drugs are isolated from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug screening notably challenging.
Confirmation for any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo purification prior to confirmation as necessary. The comprehensive laboratory workflow from Accessioning to Confirmation undergoes scrutiny at both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Drawbacks:
Note: Although commonly termed as "hair follicle tests", the examination targets the hair strand rather than the follicle under the scalp.

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.
