Accredited Drug Testing offers extensive hair follicle drug examinations throughout San Mateo, California. Whenever a hair-based alcohol or drug analysis is needed, Accredited Drug Testing provides specialized hair assessments, with facilities available across cities nationwide for administering these tests. A length of 1.5 to 2 inches on your scalp or body is generally necessary to conduct these tests. Hair analyses can identify drugs, alcohol/ETG, or other specific requirements.
Over recent years, reliance on hair follicle drug analyses has surged in drug testing procedures. Numerous employers, judicial bodies, and professionals in Substance Abuse are opting for hair drug assessments over normal urine analyses. Organizations with zero-tolerance drug guidelines, courts, and probationary instances utilize hair follicle tests. The key advantage is the prolonged detection window for drug use, lasting up to 90 days, performed under observation, and nearly tamper-proof. However, for detecting use within the past 5 days, urine tests remain the benchmark.

Hair assessments have gained recognition as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands, hair offers a comprehensive timeline of substance use. When collected near the scalp, hair can reveal a detection period of up to 90 days for alcohol and drugs. It is straightforward to obtain, reasonably tamper-resistant, and simple to transport.
A sample measuring 1.5 inches , consisting of around 200 hair strands (equivalent to #2 pencil thickness) nearest to the scalp, yields approximately 100mg, which is ideal for evaluation and validation. For EtG add-ons or tests exceeding 10 panels, 150mg is advised. Using a jeweler's scale for precision is suggested. If scalp hair is absent, an equivalent amount of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The quartet of critical steps in lab processing of a drug test result includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the lab's framework. This step verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing entries not captured by an electronic chain of custody system.
Screening is a preliminary examination for abuse substances. Though cost-effective in excluding drug presence in most samples, a positive screen must be corroborated for legal admissibility. Presumptive positive samples from Screening necessitate additional confirmation.
When a sample is presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), presenting challenges in hair drug testing execution.
Confirmation of positive Screening results employs GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumptively positive are cleansed before confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, is subjected to scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
