Accredited Drug Testing offers comprehensive hair follicle drug screening in Calhoun, Alabama. Whether you require a hair test for drugs or alcohol, our expertise in hair testing spans nationwide, with centers in every city equipped to provide this service. Typically, 1.5 to 2 inches of hair from the head or body is necessary. These tests can detect drugs, alcohol/ETG, or be tailored to other specific needs.
In recent times, drug testing has increasingly incorporated hair follicle tests. Many employers, judicial systems, and Substance Abuse experts favor hair tests over traditional urine tests. These are particularly utilized by employers with strict no-drug policies, judicial entities, and individuals on probation. The key advantage of hair testing is its extended detection window, lasting up to 90 days. Hair tests, collected under supervision, are nearly tamper-proof. However, for identifying recent drug use within the past 5 days, urine tests remain the gold standard.

Hair assessments have gained recognition as an effective means for identifying drug and alcohol usage. Hair strands offer a comprehensive overview of substance usage by embedding biomarkers within the fiber of the hair as it grows. When collected near the scalp, these samples can reveal substances over an approximate period of 3 months. Hair collection is straightforward, challenging to tamper with, and easily transportable.
A 1.5-inch portion encompassing about 200 hair strands (approximately the width of a #2 pencil) from near the scalp yields 100mg of hair, which is optimal for both screening and confirmation purposes. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. It's ideal to weigh the sample using a jeweler’s scale. Should scalp hair be unobtainable, a similar quantity of body hair may be used. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (like facial or axillary hair).
Process Overview
The laboratory's process to determine a drug test outcome involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the integration of a sample into a lab's system, validating that it was correctly sealed and dispatched, assigning an anonymous LAN (Laboratory Accessioning Number), and completing any omissions in data entry not captured by an electronic chain of custody system.
Screening serves as an initial check to detect potential drug misuse. As an economical approach, it can exclude drug usage in numerous samples; however, if the screen is positive, further confirmation is essential for court validity. Samples with presumptively positive results from Screening necessitate a secondary confirmation.
A specimen deemed presumptively positive during Screening undergoes additional Extraction, removing more hair from the initial sample. During this phase, drugs are extracted from hair at notably lower concentrations relative to other methods (e.g., urine or oral fluid), illustrating the complexity of hair drug testing.
Final confirmation of any positive screen employs GC/MS, GC/MS/MS or LC/MS/MS. All samples presuming positive undergo pre-confirmation washing as warranted. Each step, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:

Note: Although referred to as "hair follicle tests", the procedure analyzes the hair strand, not the follicle located 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.
