The company highlights expertise in clinical chemistry, immunoassay, immunohematology and molecular testing, positioning its portfolio to support clinicians in making informed decisions and improving patient outcomes.
Public filings show that QuidelOrtho’s common stock trades on The Nasdaq Stock Market under the symbol QDEL. The company identifies itself as a global provider of diagnostic technologies and notes that it serves customers in multiple regions, with prior descriptions referencing North America, EMEA, China and other international markets. Within its broader diagnostics focus, QuidelOrtho emphasizes both laboratory-based systems and point-of-care testing, reflecting a strategy that spans decentralized and high-throughput environments.
Core diagnostic capabilities
Across press releases and investor communications, QuidelOrtho describes a portfolio that includes rapid diagnostic testing, laboratory assays and informatics-enabled solutions. The company reports activity in:
- Clinical chemistry – laboratory testing that supports routine and specialized analysis of patient samples.
- Immunoassay – assays that detect specific analytes using antigen–antibody interactions.
- Immunohematology and transfusion medicine – tools that support blood typing, antibody screening and direct antiglobulin testing to inform transfusion decisions.
- Molecular testing – diagnostics that detect nucleic acid targets for conditions such as respiratory infections.
QuidelOrtho also references informatics platforms that connect instruments, data systems and clinical decision-making. In company communications, informatics is described as a means to improve laboratory workflows, data integrity and quality across decentralized testing environments.
Point-of-care and respiratory testing
In recent product announcements, QuidelOrtho has highlighted its role in point-of-care respiratory diagnostics. The company announced the availability of the QUICKVUE Influenza + SARS Test, a CLIA-waived, 510(k)-cleared rapid immunoassay for professional use. According to the company, this test provides simultaneous detection and differentiation of influenza A, influenza B and SARS‑CoV‑2 antigens from a single patient sample, with results in as fast as 10 minutes. The test is described as designed for physician office laboratories, urgent care centers, emergency departments, pharmacies and decentralized hospital labs, and is offered as a visually read, cost-conscious option within the QUICKVUE portfolio.
QuidelOrtho states that this launch expands its respiratory solutions, which also include instrumented antigen assays such as the SOFIA 2 Flu + SARS Antigen FIA. The company frames these offerings as tools to help clinicians differentiate between respiratory pathogens that present with similar symptoms, supporting timely treatment decisions and management of seasonal surges in respiratory infections.
Laboratory systems and cardiac diagnostics
On the laboratory side, QuidelOrtho reports that it offers VITROS Systems for immunodiagnostics and clinical chemistry. Company materials describe these systems as built on dry-slide, MicroWell and INTELLICHECK technologies, with an emphasis on workflow efficiency, reliability and quality clinical results in laboratories worldwide.
In cardiac care, QuidelOrtho announced that the U.S. Food and Drug Administration granted 510(k) clearance for the VITROS hs Troponin I Assay. The company states that this assay is intended for the quantitative measurement of cardiac troponin I in human plasma to aid in the diagnosis of myocardial infarction. High-sensitivity troponin testing is presented as important for faster cardiac decision-making in emergency and acute settings, and QuidelOrtho positions the assay as part of its broader cardiac testing menu on VITROS Systems.
Transfusion medicine and immunohematology
QuidelOrtho also highlights a significant presence in transfusion medicine. In connection with the AABB Annual Meeting, the company described an immunohematology portfolio that includes the MTS DAT Card for direct antiglobulin testing and the ORTHO VISION Platform. The MTS DAT Card is presented as completing a gel-based solution for direct antiglobulin testing, while the ORTHO VISION Platform combines column agglutination technology with advanced software features such as reflex testing and quality control tools.
The company also references the ORTHO VISION Max Swift Analyzer and ORTHO VISION Swift Analyzer, which it characterizes as automation-focused analyzers for immunohematology testing, and ORTHO CONNECT Lab Management Software, which is described as middleware that centralizes workflow automation for transfusion medicine laboratories and networks.
Informatics and data-driven diagnostics
Through its Science Bytes podcast and product communications, QuidelOrtho underscores the role of informatics in its strategy. Company representatives describe informatics platforms that connect instruments and data systems, support automation, and help maintain data integrity and security. These tools are presented as important for managing growing testing volumes, supporting decentralized point-of-care environments and ensuring consistent quality across lab networks.
QuidelOrtho’s communications discuss how informatics can turn data into decisions, streamline workflows, reduce error and provide traceability. This emphasis aligns with the company’s broader narrative of diagnostics that “connect insights with solutions,” linking test results to clinical decision-making.
Clinical focus areas
Across its public materials, QuidelOrtho highlights several clinical focus areas where diagnostics can influence patient care:
- Cardiovascular health – high-sensitivity troponin testing to aid in the diagnosis of myocardial infarction and support guideline-aligned decision-making.
- Respiratory illness – rapid tests and panel solutions to distinguish between pathogens such as influenza and SARS‑CoV‑2, especially in urgent care and point-of-care settings.
- Metabolic disease – discussions of emerging biomarkers and laboratory platforms for earlier detection of conditions such as diabetes, as described in company podcast content.
- Transfusion safety – immunohematology tools and software designed to support accurate blood typing, antibody detection and management of complex serological cases.
Through educational initiatives such as the Science Bytes podcast, QuidelOrtho features internal experts and external clinicians who discuss diagnostic trends, early disease detection, and the operational realities of laboratories and urgent care centers. These communications reinforce the company’s stated focus on linking diagnostics with improved patient outcomes and economic value in healthcare.
Capital structure and financial disclosures
QuidelOrtho’s SEC filings provide additional context on its operations and capital structure. The company files periodic and current reports with the U.S. Securities and Exchange Commission, including Forms 10‑K, 10‑Q and 8‑K. In an 8‑K dated August 21, 2025, QuidelOrtho disclosed that it entered into a Credit Agreement that provides term loan and revolving credit facilities, with Bank of America, N.A. as administrative agent and swing line lender and other lenders as parties. The filing describes senior secured term loan A and term loan B facilities and a revolving credit facility, along with related covenants, maturities and interest rate provisions.
Subsequent 8‑K filings in November 2025 reference quarterly financial results and a stockholder letter discussing performance and strategic priorities. These filings indicate that QuidelOrtho continues to report results, provide financial guidance and communicate with investors through earnings releases, conference calls and investor presentations.
Business scale and classification
Based on its exchange listing, global operations in diagnostics and detailed capital markets activity, QuidelOrtho fits the profile of an established medical diagnostics manufacturer rather than an early-stage or development-only entity. The company’s disclosures describe a broad installed base of laboratory systems and point-of-care tests, along with ongoing R&D in areas such as molecular platforms, AI-enabled diagnostics and informatics.
While specific revenue or market share figures are not repeated here to maintain an evergreen profile, QuidelOrtho’s regular financial reporting, product clearances and participation in major industry conferences such as AABB suggest a meaningful role in the in vitro diagnostics sector.
