Accredited Drug Testing offers comprehensive hair follicle drug testing services in Paradise, California. Whether you need testing for drugs or alcohol, we are experts in hair analysis with facilities in cities nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the crown of your head, or in certain cases body hair, is required. Hair tests can analyze for various substances, including drugs and alcohol/ETG, or be customized to meet specific needs.
The trend toward employing hair follicle drug tests in recent times is growing. Many employers, courts, and Substance Abuse experts mandate hair drug testing as an alternative to urine tests. Hair tests are favored by employers upholding zero-tolerance drug policies, judicial systems, and individuals on probation. Its key advantage lies in its extended detection period for drug consumption, usually up to 90 days, through a supervised collection that is tough to tamper with. However, urine tests remain the gold standard for identifying drug use within the last five days.

Hair analyses have emerged as an effective means to identify drug and alcohol intake. Hair retains a comprehensive record of these substances by preserving biomarkers within the growing hair fibers. When cut near the scalp, hair can reveal a detection timeframe of up to roughly 3 months for alcohol and other substances. It's easy to collect, has a low risk of tampering, and is straightforward to transport.
A 1.5-inch portion comprising about 200 hair strands (equivalent to a #2 pencil in diameter) nearest the scalp yields 100mg, the optimal sample for preliminary and confirmatory testing. For EtG additions and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't available, an equal amount of body hair can be used. By head hair, we mean scalp hair specifically, while body hair refers to other hair types (facial, axillary, etc.).
Process Overview
There are four foundational steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into the lab’s systems. This encompasses ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry missing from an electronic chain of custody record.
Screening administers an initial swift assessment for substances of abuse. Although Screening is an economical method to dismiss drug consumption in most samples, a positive finding must be validated to be legitimate in legal contexts. Any samples deemed presumptively positive in Screening require a secondary verification.
If a specimen appears presumptively positive in the Screening stage, additional hair is taken from the original sample and readied for Extraction. During this phase, drugs are drawn from hair at much finer concentrations than other techniques (e.g., urine or saliva), thus making hair drug analysis the most complicated method to execute.
Any positive screening outcome must be confirmed with GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Frequently called "hair follicle tests", these tests analyze the hair strand instead of the hair follicle underneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
