Accredited Drug Testing offers comprehensive hair follicle drug tests in Covington, Virginia. Specializing in hair testing, our centers across all U.S. cities can conduct these tests. Generally, 1.5 to 2 inches of hair from the head or body is required. Our hair analysis can test for drugs, alcohol/ETG, or be tailored to other needs.
In recent years, hair follicle drug tests have become more common for drug screening. They are favored by employers, courts, and Substance Abuse experts over standard urine tests. The primary advantage of hair testing is the extended detection window up to 90 days, collected under observation, making it nearly impossible to cheat. However, urine tests remain the most accurate for drug use within the last 5 days.

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of drugs and alcohol by embedding biomarkers within the hair strand's structure. When sampled close to the scalp, hair can reveal drug and alcohol use within an approximate 3-month span. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches, consisting of about 200 hair strands (similar in size to a #2 pencil) nearest the scalp, will yield 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair may be utilized. The term "head hair" refers specifically to scalp hair. "Body hair" includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes these four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a lab’s system. This step verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and adds any supplementary data not captured by an electronic chain of custody service.
Screening performs a preliminary assessment for drug abuse. While Screening economically excludes drug use in most samples, positive screens require confirmation for court admissibility. Presumptive positive samples in Screening necessitate secondary validation.
If hair samples test presumptively positive during Screening, more hair is drawn from the initial collection and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), thus making hair drug testing one of the most complex methodologies.
Positive screening results undergo Confirmation using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing presumptively positive are thoroughly washed before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, is conducted under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite commonly being called "hair follicle tests," the analysis targets 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.
