Why did my brother's CRP level rise rapidly after COVID infection?

Hello,

Welcome to icliniq.com. Thank you for the query. I can understand your concern. CRP (C-reactive protein) is an acute-phase protein. During infectious or inflammatory disease states, CRP levels rise rapidly within the first six to eight hours and may peak at a level of up to 35.00 to 40.0 mg/dL after 48 hours and may remain at the peak for one to five days. At the initial stage of your brother's COVID infections, viral loads may increase, and the ongoing inflammation process may rise too; for that reason, his CRP may be raised too. But after starting tablet Methylprednisolone, his CRP has declined because tablet Methylprednisolone can reduce inflammation. As inflammation begins to fall due to administration, CRP also decreases. HRCT (high resolution computed tomography) of the chest should be done to exclude COVID pneumonia. In the case of COVID pneumonia, the doctor should start antiviral medications. As your brother's oxygen saturation rate persists at 98%, his respiratory status is fine now. Take care. In case of any other query, ask me.
