In vitro Tests

Our core business is the discovery, development and manufacturing of in vitro tests for the diagnosis of various diseases that include cancer, diabetes, Covid-19, hepatitis, human papillomavirus and many others. In vitro diagnostics, or IVDs, are medical devices that analyse samples taken from the human body, such as blood, tissue or urine, using various technologies.
The samples are analysed directly at physicians' offices or in laboratories, which we supply with our tests and instruments.

Some of our tests come in the form of test strips and don’t require any instruments.
Other tests are developed to be run on instruments and come in a cassette form.


Most of our in vitro tests run on diagnostic instruments that we develop and manufacture ourselves or with external partners. Some of these devices are small, and are used to analyse a patient's blood or urine. You can find these in doctors offices and clinics. Other instruments are large analysis modules, some the size of small cars, which can be integrated to provide a seamless molecular diagnostics solution for central laboratories. These systems allow hundreds of samples to be analysed in parallel, testing for many different diseases.

The laboratory-based diagnostic systems work with advanced technologies equally as sophisticated as those you might find in modern aircraft. These analytical laboratory instruments are fully automatic, enabling the analysis of a large number of samples in a short time. In addition, advanced automation reduces the opportunity for error, which benefits patients. Thus, laboratories are able to deliver high-quality patient results in a highly efficient manner.

Our larger systems are usually run in laboratories. They can process many patient samples at once.
The smaller instruments are used in near-patient settings such as physicians' offices. They process one patient sample at a time.

Digital Solutions

The digitisation of the healthcare system opens up a host of new possibilities that can improve the quality of healthcare and make services more affordable. At Roche, we have developed a broad portfolio of digital solutions for physicians and patients.

For laboratories, we offer software that supports specialists in their diagnostic work, such as pathologists in the interpretation of tissue samples through artificial intelligence. These tools do not replace pathologists, they enable them to be more efficient and confident in their diagnoses. We also develop solutions that automate and interconnect all areas and devices of a laboratory. This leads to greater efficiency and less susceptibility to errors in the laboratory. The patient benefits through high-quality laboratory results.

Artificial intelligence can support pathologists in the interpretation of tissue samples.

In addition to the broad portfolio of diagnostic tests that support physician decisions, we also provide them with clinical decision support: Using individual patient data and the latest medical information, algorithms and artificial intelligence suggest treatment options. This supports physicians in selecting the optimal therapeutic approach for each patient based on the large amount of data available.

Digital solutions can help physicians in decision-making.

For patients, we primarily offer digital diagnostic solutions for self-monitoring. For example, for people who have diabetes, there is a smartphone app that helps them manage their diabetes. We are also developing tools to deliver test results quickly to patient smartphones in areas with limited resources.

Digital solutions can help people with diabetes to manage their disease more efficiently in day-to-day life.
