Accredited Drug Testing provides thorough hair follicle drug testing services in Dixon, Missouri. For those in need of hair drug or alcohol testing, our expertise is in hair analysis, with centers across the nation ready to carry out these tests. In most instances, hair from the crown of the head or body—ranging 1.5 to 2 inches—is used. Analyzed tests can detect drugs, alcohol/ETG, or be customized.
The use of hair follicle tests has increased in recent times for drug testing purposes. Employers, legal systems, and professionals dealing with Substance Abuse are turning to hair tests instead of the more common urine tests. These tests align with strict drug policies by offering a longer detection window of up to 90 days and are collected under supervision, making them hard to tamper with. However, for detecting recent drug use within five days, urine tests remain more precise.

Hair testing has emerged as a potent method in identifying drug and alcohol consumption. By capturing biomarkers within the fibers of a growing hair strand, hair offers a prolonged history of substance use. Hair collected near the scalp can reveal up to an approximate 3-month window for detecting drugs and alcohol. It is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch strand comprising around 200 hairs (roughly the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg specimen is advised. We suggest using a jeweler's scale for weighing. If scalp hair is unavailable, a comparable amount of body hair may be gathered. When mentioning head hair, it refers strictly to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's system, which includes confirming the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and finalizing any further data entry absent in an electronic chain of custody system.
Screening offers a preliminary rapid check for substances of abuse. Although Screening presents a cost-efficient method to dismiss drug use in most samples, a positive screening necessitates confirmation to be court-admissible. Samples that are presumptively positive in Screening require secondary confirmation.
Should a sample be found presumptively positive in the Screening stage, more hair is extracted from the initial specimen for the Extraction phase. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), rendering hair drug screening the most complex methodology to execute.
Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The entire laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation in ISO / IEC 17025 standards.

Limitations:
Note: While commonly termed as "hair follicle tests," the analysis is conducted on the hair strand itself, rather than the hair 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.
