DiaSorin focuses its efforts on several fields of immunodiagnostics: infectious diseases, bone and mineral, endocrinology, hypertension, oncology, gastrointestinal infections, autoimmunity and brain and cardiac markers.

The company is also active in molecular diagnostics for infectious diseases and for the detection of some forms of leukemia.^[4]

In 2021 DiaSorin also entered into the Life Science space, through the acquisition of Luminex Corporation, gaining access to its Multi-Analyte Profiling (xMAP) technology and to its Flow Cytometry business

DiaSorin develops, manufactures and markets tests for the diagnosis of infectious diseases or hormonal disorders. The immunodiagnostic and molecular tests are aimed at both private and hospital analysis laboratories worldwide.

In immunodiagnostics, DiaSorin offers the market proprietary-based platforms on the CLIA^[5] and ELISA^[6] technologies.

In molecular diagnostics, DiaSorin offers proprietary platforms that cover the three phases of the testing process: extraction, amplification and detection.^[7]

The origins of the company date back to 1968, when near on an initiative of Fiat and Montecatini, the "Sorin Biomedica" was founded by the "Società Ricerche Impianti Nucleari - Sorin".^[8] In 1997 American Standard acquired Sorin Biomedica, together with Immunonuclear Corporation (Incstar, Inc.). The two companies formed the Medical System Group of American Standard that later on came to include also Sienna Biotech, Inc^[9] DiaSorin became an independent Italian group in 2000, through a management buyout operation led by Carlo Rosa and Gustavo Denegri.^[10]

The etymology of the name contains the acronym of Sorin, "Nuclear plant research company", the company established in the 1960s, and "Dia" which stands for Diagnostics. In 1997 Sorin decided to build upon the activities relating to in vitro diagnostics into a company that took on the name of DiaSorin Vercelli.^[11]

In 2002 DiaSorin acquired BYC Sangtec and the rights to the Liaison platform. The commercial expansion led to the opening of new branches in Mexico, Israel, and China. The Liaison portfolio was enriched with products for new and clinical specialty areas. In the same year, tests previously developed with ELISA technology were converted to the most recent and automated CLIA.^[8]

On July 19, 2007, the DiaSorin title debuted at Borsa Italiana Stock Exchange.^[12]

In 2014 the company obtained the approval of hepatitis and retrovirus tests in China; in the same year, DiaSorin launched new tests to detect leukemias. DiaSorin Group signed an agreement in 2015 with Beckman Coulter for the commercialization in China of DiaSorin hepatitis and HIV tests.^[13] In 2016, DiaSorin and Beckman Coulter signed an additional partnership, with the aim to provide customers in the U.S. the same hepatitis and HIV tests. The two companies are working together to submit the products to the Food and Drug administration (FDA) for approval and commercialization in the U.S.^[14] In this year, the group acquired of Focus Diagnostics’ business unit, enabling it to expand its activities in molecular diagnostics.^[15][16]

In 2017, a partnership with Qiagen offered an automated solution for detection of tuberculosis with QuantiFERON-TB Gold Plus available on the Liaison analyzers. That was also the year of the Siemens Healthineers ELISA business acquisition.^[17]

In October 2018 the Saluggia branch began a partnership with Meridian for the distribution of a Helicobacter pylori detection test in the United States and United Kingdom. The companies have put in place a framework under which they may work together on the development of new tests and products.^[18]

In 2019 the commercial launch of Liaison XS approval of latent tuberculosis test in the United States.^[19]

In 2020 DiaSorin signed an exclusive license agreement with TTP for the automation of molecular diagnostic tests on a Point-of-Care platform.^[20]

In April 2021, in partnership with QIAGEN, DiaSorin launched in countries accepting the CE Mark the LIAISON LymeDetect test for the early diagnosis of Lyme Borreliosis, based on the QuantiFERON technology.

On 14 July 2021 DiaSorin announced the completion of the acquisition of Luminex Corporation.^[22][23][24]

Diasorin's response to the Covid-19 pandemic edit

On 7 April 2020, DiaSorin announced the development of a new IgG CLIA test to identify antibodies against SARS-CoV-2 antibody, test that allows to detect antibodies directed against the virus in patients’ serum samples, identifying subjects who have developed an immune response to the virus, offering a tool for epidemiologic assessment of populations.^[25]

On 25 April 2020, DiaSorin received Emergency Use Authorization from the U.S. Food and Drug Administration for a new serologic test for COVID-19.^[26]

On May 2, 2020, DiaSorin received approval for the commercialization of the LIAISON SARS-CoV-2 S1 / S2 IgG test in Brazil from ANVISA, the Brazilian health regulatory agency, and on May 12, 2020, the same test obtained approval from Health Canada, the Canadian government department responsible for federal health policy. This latter officially issued approval made the DiaSorin serological test the first to receive authorization in the country.^[27][28]

On June 30, DiaSorin announced the launch of the new LIAISON SARS-CoV-2 IgM test, CE marked and made available in the United States through the validation notification submitted to the Food and Drug Administration (FDA), which was followed by the authorization request for emergency use, as required by the "Policy for Coronavirus Disease-2019 Tests During the Public Health Emergency (Revised)". DiaSorin announced it obtained the Emergency Use Authorization by the FDA on October 1, 2020.^[29][30]

On September 7, 2020,  DiaSorin announced that it has received FDA Clearance for its Simplexa™ Flu A/B & RSV Direct Gen II kit. The molecular assay can be run alone or alongside the Simplexa COVID-19 Direct kit, allowing for differential diagnosis of SARS-CoV-2, influenza A (Flu A), influenza B (Flu B), and respiratory syncytial virus (RSV).^[31]

On September 16, 2020, DiaSorin attained CE Marking for the addition of saliva specimens for use with the Simplexa™ COVID-19 Direct assay.^[32][33]

On October 1, 2020,  DiaSorin received U.S. FDA Emergency Use Authorization (EUA) for its LIAISON SARS-CoV-2 IgM test. The LIAISON SARS-CoV-2 IgM test will be available on the LIAISON XL platforms installed in the U.S. market, using chemiluminescence immunoassay (CLIA) technology for the qualitative determination of specific IgM antibodies to SARS-CoV-2 in human serum or plasma samples. The test identifies the presence of IgM antibodies in patients who have been infected with SARS-CoV-2, enabling the distinction between newly infected and past-infected patients.^[34][35]

On October 26, Diasorin announced the obtainment of the CE mark for the launch of the new Liaison Sars-Cov-2 Ag antigen test, capable of detecting COVID-19 on symptomatic patients and determining their viral load.^[36] The test received U.S. FDA Emergency Use Authorization (EUA) on March 29, 2020.^[37]

On January 11, 2021, DiaSorin launched in countries accepting the CE Mark the LIAISON SARS-CoV-2 TrimericS IgG test. The test was developed using the full length SARS-CoV-2 Spike protein in its Trimeric form, which perfectly mimics the native conformation of the protein. The test is therefore able to detect the full variety of the natural immune response to the virus reducing the risk of false negative results. The test, originally available in countries accepting the CE Mark, received U.S. FDA Emergency Use Authorization (EUA) on May 20, 2021.

On April 6, 2021, DiaSorin launched in countries accepting CE Mark a new Point-of-Care immunodiagnostic platform, the LIAISON IQ, developed in partnership with Lumos Diagnostics together with a first test to detect antibodies against SARS-CoV-2. On May 25, 2021, an additional test was made available on the LIAISON IQ platform, to detect the COVID-19 antigen in nasal and nasopharyngeal swabs. Both tests use lateral flow technology.

On May 21, 2021, DiaSorin launched a molecular diagnostic test to easily detect the mutations associated with the most common variants of SARS-CoV-2.^[38]

The research team of about 200 people is dedicated to the development of solutions for specialized tests to support doctors and laboratory managers in the processing of diagnoses of even niche diseases. The technologies of immunodiagnostics and molecular diagnostics applied to the tests of DiaSorin are based on automated technological platforms developed by partner companies based on specifications indicated by DiaSorin. Such platforms are open to interconnection with the ones of other diagnostic operators.^[39]

Analysis kits edit

DiaSorin tests are biochemical components that aim to determine the presence of a specific element (virus, hormone, etc.) in the sample taken from the patient. The two technologies used, immunodiagnostic and molecular diagnostic, identify the presence of the component sought—even in minimal quantities, to define its characteristics.

The areas of DiaSorin's offer for analysis kits in the specialty immunodiagnostics sector are the following:

• Infectious diseases

• Gastrointestinal infections

• Bone and mineral metabolism

• Endocrinology

• Hypertension

• Oncology

• Onco-hematology

• Autoimmunity

In particular, in the field of molecular diagnostics, DiaSorin has focused its research on the area of infectious diseases, with tests based on different matrices—including blood, cerebrospinal fluid, skin, and mucocutaneous swabs.^[40]
