In Penn Valley, California, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Whether you're in need of a drug or alcohol test, our specialty is hair testing, with nationwide locations that can accommodate these tests. Typically, 1.5 to 2 inches of hair from your head or body suffices for testing. Our hair analyses can screen for drugs, alcohol/ETG, and offer personalized testing solutions.
Of late, hair follicle drug tests have gained traction as a preferred drug testing method. Employers, courts, and substance abuse experts often opt for these over conventional urine tests. Organizations with strict drug policies, judiciary systems, and probation services utilize hair tests for their extensive detection window, lasting up to 90 days, observed sample collection, and difficulty to tamper. However, urine tests still excel in detecting very recent drug usage within the last five days.

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can offer a detection window of up to around 3 months for alcohol and drugs. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) located closest to the scalp will yield 100mg, which is the optimal sample size for screening and verification. For EtG, additional tests, or panels exceeding 10, it is advisable to collect 150mg. It is recommended to use a jeweler’s scale for measuring the specimen. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. When discussing head hair, it refers exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the laboratory consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first processed into the lab’s system. This step involves checking that the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.
Screening involves a rapid preliminary test for substances of abuse. Although Screening cost-effectively excludes drug use across most samples, a positive result must be confirmed to stand in legal proceedings. Any samples with a presumptively positive result in Screening must undergo further verification.
If a sample tests presumptively positive at the Screening phase, additional hair is taken from the initial sample for Extraction preparation. At this point, substances are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), highlighting the complexity of conducting hair drug screening.
Confirmation of any positive result from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptive positive are washed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is reviewed following both the CAP (College of American Pathologists) Hair designation standards and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests", these tests assess the hair strand rather than the follicle located beneath 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.
