Providing comprehensive hair follicle drug testing services in Calexico, California, Accredited Drug Testing specializes in hair testing and has nationwide centers capable of conducting these tests. A length of 1.5 to 2 inches of hair from your head or body is generally needed. Hair tests effectively detect drugs, alcohol/ETG, or other tailored testing needs.
Recently, hair follicle drug tests have become more prevalent in drug testing methods. Numerous employers, legal systems, and Substance Abuse experts mandate hair tests over standard urine tests. These tests are favored by organizations enforcing strict drug use policies, courts, and probationers. A key advantage of hair tests is their extended drug detection period of up to 90 days, with direct supervision making it nearly cheat-proof, though urine remains best for recent drug use screening of up to 5 days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, providing an extended timeline of substance use. Sampling hair near the scalp can reveal drug or alcohol use over approximately 90 days. Collection is straightforward, tampering is challenging, and shipping is convenient.
A sample size of 1.5 inches consisting of around 200 hair strands (equivalent to the width of a #2 pencil) close to the scalp is needed to achieve 100mg, which is optimal for both screening and confirmation tests. For EtG, additional tests, or tests beyond 10 panels, it's advisable to use 150mg of the sample. Utilizing a jeweler’s scale ensures accurate measurement. If scalp hair is inaccessible, a comparable amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (such as facial or axillary).
Process Overview
The primary stages in processing a laboratory drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a laboratory’s system. This phase ensures the sample’s proper sealing and shipment, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any supplemental data entry lacking from an electronic chain of custody framework.
Screening offers an initial rapid assessment for drugs of abuse. While this cost-efficient step can often rule out drug use in many samples, any positive findings during this phase must be validated to be court admissible. Samples that show a presumptive positive in Screening necessitate further confirmation.
Should a sample be presumptively positive at the Screening stage, more hair from the original sample is prepared for Extraction. This involves extracting drugs from hair at concentrations far lower than in alternative techniques (like urine or oral fluid), making hair screening methodologies among the most intricate.
Drugs identified during the Screening phase undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives are cleaned before proceeding to confirmation as required. The entire sequence from Accessioning through to Confirmation is evaluated according to both CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite the common term "hair follicle tests", the analysis focuses on the hair strand, not the follicle 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.
