A Revolutionary Approach to Testing
Introducing the Promus Pathway by Promus Diagnostics—where advanced technology meets unparalleled efficiency. Our infectious disease test menu provides comprehensive coverage of pathogens and resistance genes, ensuring no clinically relevant infection is overlooked. Designed with healthcare providers in mind, our testing panels are tailored to clinical differentials for seamless ordering while encompassing all essential targets.
We've eliminated complicated metrics with proprietary conversion methodologies developed by our in-house scientists, delivering reports that are both precise and easy to interpret. With expedited turnaround times and results available as soon as the next day, we eliminate delays, reduce antimicrobial guesswork, and empower informed decision-making.
Better testing, better outcomes. It's that simple.

A Revolutionary Approach to Testing
At Promus Diagnostics, we merge cutting-edge PCR technology with the foundational art of microbiology, embodying the true spirit of stewardship that our name represents. Our mission goes beyond providing results—we are committed to antimicrobial stewardship, ensuring that every test we perform supports the responsible use of antimicrobials, reducing resistance development, and preserving the effectiveness of current therapies.
Understanding the challenges clinicians face daily, our in-house team of scientists and physicians continually enhances laboratory methods, refines reporting algorithms, and aligns treatment regimens to meet the unique needs of healthcare providers across specialties. By offering the most comprehensive approach to infectious disease testing, we have redefined the industry standard while upholding the principles of stewardship in healthcare.
Our infectious disease panels are designed to detect critical pathogens and resistance genes that impact antimicrobial therapy. With a dual approach, we offer comprehensive panels featuring extensive targets and syndromic panels tailored to your patient’s symptoms and clinical differential. This ensures precise testing while avoiding unnecessary overtesting, helping to reduce the financial burden on the healthcare system while supporting evidence-based care.
We’ve also transformed the potential of PCR with our proprietary reporting methods. Unlike standard PCR labs that report results in DNA copies/mL or cells/mL, we provide results in CFU/mL, units aligned with clinical guidelines (i.e., Up To Date) for direct interpretability. This innovation eliminates guesswork, prevents overtreatment, streamlines clinic workflows, and empowers clinicians to make informed, evidence-based treatment decisions.
At Promus Diagnostics, we are not just advancing diagnostics. We are driving smarter healthcare through innovation, stewardship, and precision.

FEATURING
Promus Diagnostics is the first PCR laboratory to report in true clinical units of CFU/mL. Most other PCR laboratories report culturable organisms in DNA copies/mL, a metric that is neither equivalent to CFU/mL nor consistent with current treatment guidelines. Reporting in DNA copies/mL can lead to overtreatment, directly opposing our commitment to antimicrobial stewardship.

For over 50 years, Culture & Sensitivity (C&S) testing has been considered the "gold standard" for identifying and diagnosing infections. This traditional method quantifies infectious burden using Colony Forming Units per volume (CFU/mL) and employs Antibiotic Susceptibility Testing (AST) to determine antibiotic resistance and recommend therapy.
However, C&S has significant limitations. C&S often fails to grow or identify many pathogens that PCR technology can detect. This can result in undetected infections, compromising patient care. Additionally, C&S typically takes over 48 hours to complete, with an additional 24 hours needed for AST, totaling more than 72 hours. During this time, healthcare providers face the difficult decision of whether to treat empirically or delay treatment, potentially prolonging patient discomfort and increasing the risk of complications.
STANDARD PCR

PCR is increasingly being adopted in the medical field. Currently, most PCR labs can identify 10-15 relevant pathogens per panel and detect 5-10 antimicrobial-resistant genes. Results are typically available within 48 hours of specimen arrival, which is both faster and more comprehensive than culture and sensitivity (C&S) testing.
However, many pathogens and resistance genes still go undetected, potentially leading to undertreatment or insufficient information for evidence-based decision-making. Additionally, many PCR labs report results in units of DNA per volume (copies/mL) rather than the more familiar CFU/mL used in current guidelines. This inconsistency can create challenges for medical providers when treating patients based on established CFU/mL standards.

PCR powered by our proprietary Promus Pathway is the preferred option for many healthcare providers nationwide. Promus Diagnostics is the only PCR lab capable of identifying, isolating, and designing methods to proliferate over 100 live pathogens across multiple infectious disease assays. Depending on the test chosen, we offer up to 94 targets on a single panel. With over 100 pathogen targets and 30+ resistance gene targets, we offer the most comprehensive testing options on the market.
Additionally, our Promus Pathway simplifies reporting. All results are 95% sensitive and reported in true CFU/mL, allowing providers to make evidence-based treatment decisions that follow established guidelines. We eliminate the guesswork of converting copies/mL to CFU/mL. All reports are delivered next day and include an industry-leading treatment map that aligns with current treatment guidelines.
