Accredited Drug Testing offers comprehensive hair follicle drug tests in North El Dorado, CA. For those in need of hair or alcohol testing, we specialize in hair-based assessments. Our national facilities, located across all U.S. cities, can administer these tests. Generally, 1.5 to 2 inches of hair from the head or body is needed. Hair samples can analyze drugs, alcohol, or be customized for specific needs.
In recent times, drug testing methods increasingly rely on hair follicle tests. Many employers, judicial systems, and substance abuse professionals opt for hair tests over the conventional urine tests. Employers with strict no-drug policies, courts, and probationers find hair tests beneficial. The key benefit of hair testing is its longer detection window, typically up to 90 days. It requires an observable collection process and is almost impossible to tamper with. Yet, for drug use detection within the past 5 days, urine tests remain the precise choice.

Perceived as a robust method, hair testing stands out for detecting drug and alcohol consumption. Hair strands capture biomarkers in their fibers, offering an extended timeline of drug or alcohol consumption. When taken near the scalp, hair can grant a detection frame of approximately three months for substances. It’s easy to collect, harder to tamper with, and simple to transport.
A 1.5-inch sample, roughly 200 strands (the approximate size of a #2 pencil) next to the scalp, assures about 100mg of hair, which is perfect for analysis and confirmation. For EtG and add-ons over 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing is suggested. If no scalp hair is available, a similar volume of body hair is acceptable. "Head hair" indicates scalp hair alone, whereas "body hair" includes other hair types like facial or axillary hair.
Process Overview
Drug test result processing in a lab comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves inputting the sample into the lab’s system initially. This phase ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any missing information not included in an electronic chain of custody protocol.
Screening provides a quick initial assessment for drugs of abuse. Although cost-efficient for ruling out usage across most samples, positive screen results need confirmation for court validity. Any samples presumed positive during Screening require another confirmation step.
In cases of presumptive positivity during Screening, further hair is extracted from the original specimen for Extraction. Drugs are drawn out at a much lower concentration than other methods like urine or oral fluid, presenting why hair drug testing is particularly challenging.
Confirmatory analysis for any positive result employs GC/MS, GC/MS/MS or LC/MS/MS techniques. Presumptive positives undergo a wash before confirmation if required. The entire procedure, from Accessioning through Confirmation, is evaluated under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Hair drug testing advantages:
Drawbacks:
Note: Although called "hair follicle tests", the analysis targets the hair strand itself, 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.
