Laboratory markers, including levels of interleukins, CRP, ferritin, platelets, and lactate dehydrogenase, on the other hand, endure time delay in processing and testing availability, particularly for cytokine measurements that may be more well defined and more foundationally central to identifying CRS but are not commonly measured in the community hospital setting or in the outpatient setting. Here, CRP is linked to congenital rubella syndrome.
