Immunoassay Testing

Bring confidence to your lab, improve productivity, and advance patient care with immunoassay testing solutions from bioMérieux: offering the gold standard in immunoassay analyzers and assays.

What is an Immunoassay?

Immunoassays enable the identification and quantification of the presence of antigens and/or antibodies in a given sample (serum, plasma, blood, etc.). This is based on the immune reaction that occurs when an antibody recognizes a specific antigen in the sample being tested.

It is possible to detect and/or quantify the following:

  • The different types of antigens (viruses, bacteria, parasites, hormones, and markers that are specific to certain diseases).
  • The response to these antigens through the intermediary of antibodies present in the body. Immunoassays are used by centralized and decentralized laboratories, blood banks, emergency wards and fertility centers in both developed and developing countries. This technique is applied, for example, in the measurement of markers of infectious diseases, sepsis, cardiovascular diseases, and cancer. 

Why is Immunoassay Testing Important?

Immunoassay testing is an important tool in the field of diagnostics and provides key and sometimes critical information at multiple points along the healthcare continuum, from risk assessment and early diagnosis to treatment, patient follow-up, and disease management.  

  1. Diagnosis of diseases: Immunoassay testing is used to diagnose a wide range of diseases, including infectious and cardiovascular diseases, and cancer. By detecting the presence of specific molecules in the blood or other bodily fluids, clinicians can identify the underlying cause of symptoms to help determine the appropriate treatment plan for patients.
  2. Monitoring treatment: Immunoassay testing is also used to monitor the effectiveness of treatment for certain infections and diseases. By measuring the levels of specific molecules over time, clinicians can determine whether the treatment is working or if escalation or de-escalation with more appropriate antibiotics is needed. 

What Challenges are Laboratories Facing with Immunoassay Testing?

Immunoassay testing allows clinicians to perform a variety of diagnostics tests including immunochemistry, infectious disease, and emergency and critical care panel tests. A wide range of increasingly sophisticated diagnostic tests are used to establish or confirm a diagnosis, to determine appropriate treatment, and to monitor its efficacy. Clinicians rely on rapid diagnostics, but also demand quality and performance. Because all labs are operating in the context of cost pressure due to a highly competitive market, clinicians need to be able to run the right tests at the right time and get accurate information quickly.
