Accredited Drug Testing provides comprehensive hair follicle drug testing services in Oak, Nebraska. If you require a hair drug or alcohol analysis, our expertise in hair examinations is unmatched, with testing locations in every major city across the country. Typically, you will need 1.5 to 2 inches of hair from your head or body. Hair analyses are available for drugs, alcohol/ETG, and other personalized testing needs.
Recently, hair follicle tests have become a preferred method for drug detection. More employers, courts, and substance abuse specialists opt for hair analysis over the common urine test. These tests suit employers enforcing strict drug policies, legal systems, and individuals under probation. A key advantage of hair testing is its longer drug detection capability of up to 90 days, with a highly monitored collection that is difficult to tamper with. Nevertheless, for recent drug use detection within five days, urine tests remain the most precise.

Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drugs by securing biomarkers within the strands as they grow. By sourcing hair near the scalp, it allows detection of up to a 3-month span for alcohol and drugs. Hair is straightforward to gather, challenging to tamper with, and convenient to ship.
Collecting a 1.5-inch section of about 200 hair strands (roughly equivalent to a #2 pencil) near the scalp provides 100mg of hair, the ideal amount for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, 150mg of hair is advised. It's suggested to measure the specimen with a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be collected. By head hair, we mean scalp hair, whereas body hair encompasses other types such as facial or axillary.
Process Overview
The four principal stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial integration of a sample into the lab's system. It involves checking that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any other data entry not covered by an electronic chain of custody system.
Screening is a preliminary inspection for substances of abuse. Although Screening is economical for negating drug use for most samples, any positive results need confirmation to be court-admissible. Samples that test presumptively positive during Screening require a subsequent confirmation.
Should a sample be presumptively positive at the Screening phase, additional hair is extracted from the initial specimen for the Extraction step. Here, drugs are withdrawn from hair at a significantly lower concentration compared to other techniques (like urine or oral fluid), which is why hair drug testing is among the most challenging methodologies.
Confirmation of any positive results in Screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo washing before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standard accreditation.

Note: Although often labeled as "hair follicle tests," the test itself analyzes the hair strand, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
