In Saint Charles, Missouri, Accredited Drug Testing offers comprehensive hair follicle drug testing services. For those in need of a hair drug or alcohol test, our expertise in hair testing is unparalleled, with testing centers located in all cities nationwide. Typically, 1.5 to 2 inches of hair from the crown of the head or body is required for testing. Our hair tests can screen for drugs, alcohol/ETG, or other tailored testing options.
Recently, the hair follicle drug test has gained preference over traditional methods. Employers, courts, and Substance Abuse experts increasingly favor hair tests instead of the more common urine tests. Hair follicle testing is ideal for employers with strict no-drug policies, judicial cases, and probationary monitoring. A key advantage is its extended detection window, spanning up to 90 days, with an observed collection process making it nearly impossible to manipulate. However, for drug use detection within the last 5 days, urine tests remain the gold standard.

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair acts as a repository for a long-term record of alcohol and drugs by capturing biomarkers within the growing hair strand's fibers. When obtained near the scalp, hair samples offer an approximate 3-month detection period for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.
A 1.5-inch section of around 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for examination and verification. For EtG, additional requests, and/or tests exceeding 10 panels, it is advised to gather 150mg of the sample. It is advisable to weigh the sample with a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. In referring to head hair, it signifies scalp hair exclusively. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The primary phases in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the laboratory's system. This step verifies the sample's proper sealing and transportation, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entries not covered by an electronic chain of custody system.
Screening consists of a preliminary rapid assessment for drugs. While Screening is a cost-effective means to exclude drug use in most cases, a positive screen must be confirmed for legal admissibility. Samples that presumptively screen positive require a secondary confirmation.
If Screening indicates a presumptive positive, further hair is extracted from the original sample for Extraction. In this phase, substances are extracted from the hair at a much lower concentration than other methods (e.g., urine or oral fluid), presenting a greater challenge for hair drug screening.
Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although often termed "hair follicle tests", the procedure evaluates the hair strand rather than 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.
