Faster and safe from corona isolation with a new test method

For this study, scientists from the MUMC+ and Zuyderland Medical Center compared data from approximately 500 former and approximately 90 new patients during their stay in isolation. They work together with researchers from Radboudumc, LUMC, Medical Center Leeuwarden, Catharina Hospital Eindhoven, Eindhoven University of Technology and patient (organisations).


The flow of corona patients is essential. During the various corona waves, permanent occupation of isolation rooms led to great pressure on healthcare. In addition, isolation is associated with physical and psychological strain for both patients and employees. Currently, patients must have a negative PCR test result for two days in a row before they can be removed from isolation. While it is known that – even with a positive result – they no longer have to be contagious.


Central to the research is the CoLab score. This score is determined on the basis of blood results and is an alternative to the well-known PCR test. This method of testing is advantageous because it is available 24/7 and involves virtually no extra costs because 10 standard laboratory results are used. These results are usually part of the standard examination of a patient in the ICU. Waiting for the PCR result after a swab with a swab in the throat and nose, which takes much longer than the CoLab score, may then no longer be necessary.

To compare

The blood values ​​and test results of the 500 former patients are analysed. The CoLab score of the 90 new patients in the study will be determined daily and compared with the standard PCR test and a new PCR test that can exclude the presence of live (infectious) virus particles. The usual PCR test does not distinguish between live and dead (no longer contagious) virus particles and therefore also picks up dead virus particles. In this way, the researchers can show that a patient with a normalized CoLab score is no longer infectious and can be safely removed from isolation.
