• Chest X-ray or CT chest will be recorded.

• Laboratory to perform the following tests:

Complete blood count with differential counts, COVID -19 PCR test by nasopharyngeal swab. C-reactive protein and serum ferritin level. Renal function tests (RFTs) (serum creatinine), Liver function tests (LFTs) (alanine amino transferase (ALT), aspartate amino transferase (AST), total and direct bilirubin), Coagulation test; prothrombin time and INR.
