Accredited Drug Testing offers extensive hair follicle drug screening in Dillwyn, Virginia. When a hair drug or alcohol test is required, they specialize in hair testing with facilities in every major U.S. city capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head or body suffices. These tests can evaluate for drugs, alcohol/ETG, or be customized as needed.
Over recent times, drug testing practices have increasingly transitioned towards using the hair follicle method. Employers, judicial systems, and Substance Abuse experts favor hair drug tests over the conventional urine test. Such tests cater to organizations enforcing strict drug-free policies, legal entities, and those on probation. A hair follicle test's notable advantage is its comprehensive drug use detection span, lasting up to 90 days, collected perceptibly and challenging to falsify. However, for recent drug use within five days, urine tests still maintain superior accuracy.

Hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair retains long-term evidence of drugs and alcohol by locking biomarkers within the fibers of the developing hair strand. When taken from just above the scalp, hair can offer an up to approximately 3-month detection timeframe for alcohol and other drugs. Hair is easy to collect, hard to tamper with, and simple to transport.
A 1.5-inch sample of roughly 200 strands of hair (similar to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is unobtainable, a similar amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four principal steps in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary processing of a sample into a laboratory’s system. This involves ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not offered by an electronic chain of custody system.
Screening involves an initial rapid check for drugs of abuse. Although Screening is a cost-effective method to exclude drug usage in the majority of samples, a positive screen must be confirmed to be permissible in court. Any samples that are presumptively positive in Screening do necessitate a secondary confirmation.
If a sample is presumptively positive during the Screening step, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are drawn out from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging methodology to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to 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.
