Reference excerpt

Ortho Clinical Diagnostics (now QuidelOrtho) is an in vitro diagnostics company that made products and diagnostic equipment for blood testing. Ortho served two primary industries in the medical field: clinical laboratories, by producing platforms and assays that test for a variety of diseases, conditions, and substances; and immunohematology, by providing the means to ensure blood transfusion recipients receive appropriate and compatible blood. Johnson and Johnson acquired Eastman Kodak's Clinical Diagnostics Division in 1994 (to form Johnson & Johnson Clinical Diagnostics), which was then merged with Ortho Diagnostic Systems in 1997. QuidelOrtho's global corporate offices are in Raritan, New Jersey, while their global research and development center is in Rochester, New York. In 2014, The Carlyle Group purchased the company from Johnson & Johnson for $4.15 billion. Ortho Clinical Diagnostics now operated as an independent company, up until its acquisition by Quidel Corporation for $6 billion, on May 27, 2022.

History 1939: Ortho Products, Inc., is formed in Linden, New Jersey, as a division of Johnson & Johnson. 1944: Philip Levine, in the field of hematology, joins Ortho Products to continue his research into the mechanics of the Rh system in human blood. 1997: Ortho Diagnostics Systems and Johnson & Johnson Clinical Diagnostics merge and begin operating as Ortho Clinical Diagnostics. 2001: Ortho becomes the first diagnostic company to receive US FDA approval for automated random access hepatitis tests. 2006: Ortho launches the first FDA-licensed test to screen blood donations for exposure to Chagas disease. 2014: The Carlyle Group acquires Ortho Clinical Diagnostics for $4.15 billion. 2015: Ortho receives FDA clearance for its ORTHO VISION Analyzer, which automates the full range of immunohematology testing and helps improve the safety of blood transfusions by reducing laboratories' reliance on manual methods. 2017: FDA approves Ortho's HIV Combo test for the Vitros immunodiagnostic system. The test detects both HIV-1 and HIV-2 antibodies and the p24 antigen, and enables detection of HIV-1 acute infection earlier than previous assays. 2021: Quidel announced it would acquire Ortho Clinical Diagnostics Holdings for $6 billion in cash and stock, increasing the range of COVID-19 antigen and antibody tests the business is able to offer.

Business operations Ortho produces in-vitro diagnostics equipment and associated assays and reagents, serving the clinical laboratories and immunohematology sectors of the medical field. Ortho sells its products in more than 125 countries and is targeting emerging markets for future growth.

Worked examples

Example 1 — a first encounter with Ortho Clinical Diagnostics

Start with the simplest possible case. Write down what Ortho Clinical Diagnostics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ortho Clinical Diagnostics before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ortho Clinical Diagnostics ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ortho Clinical Diagnostics

In research: Ortho Clinical Diagnostics appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ortho Clinical Diagnostics in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ortho Clinical Diagnostics is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1994 establishments in New Jersey, American companies established in 1994, Companies based in New Jersey, so understanding it makes those chapters shorter.
In everyday life: Look for Ortho Clinical Diagnostics outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
