Accredited Drug Testing provides comprehensive hair analysis for drugs in Rohnert Park, California. If you're in need of a hair-based drug or alcohol screening, our expertise lies in hair diagnostics, and we have facilities across all cities nationwide for conducting these tests. Typically, 1.5 to 2 inches of hair from the head or body is necessary. Hair samples can be tested for drugs, alcohol/ETG, or other specialized options.
In recent times, the approach to drug testing has increasingly opted for hair follicle examinations. Many employers, legal authorities, and addiction specialists are choosing hair tests over the traditional urine analyses. These tests are favored by workplaces with stringent drug-free mandates and by courts, as well as individuals under probation. A significant advantage of hair follicle tests is their extended detection capability for drug use, usually up to 90 days, ensuring an observed collection process that’s virtually tamper-proof. However, for detecting recent drug use within the past 5 days, urine tests remain the top choice.

Hair testing has emerged as a potent tool for identifying drug and alcohol consumption. Hair encapsulates a lengthy record of alcohol and drug activity by embedding biomarkers within the fibers of the maturing hair strand. When harvested near the scalp, hair can offer nearly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, tough to tamper with, and uncomplicated to transport.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (around the width of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the perfect sample for screening and validation. For EtG, add-ons, or evaluations beyond 10 panels, a 150mg specimen is suggested. Using a jeweler’s scale for weighing the specimen is advisable. If scalp hair cannot be accessed, a similar quantity of body hair can be utilized. "Head hair" specifically means scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary processing of a sample into the lab's system. This includes checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.
Screening involves an initial rapid assessment for drug abuse. Screening provides a cost-effective means to discount drug usage in most samples, though a positive screen must be confirmed to be valid in court. All samples presumed positive in Screening require an additional confirmation.
If a sample is suspected positive in the Screening phase, additional hair is taken from the initial specimen for Extraction. In this step, drugs are isolated from hair at a much lower saturation than in other methods (e.g., urine or oral fluid), explaining why hair drug screening is among the most challenging methods to execute.
Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo washing before confirmation, if needed. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 guidelines.
Advantages of hair drug testing:
Limitations:

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.
