CRP and lymphopenia: Lymphopenia (<1.1 x 109/L) and elevated inflammatory markers, CRP (>10 mg/L) and ESR (>35 mm/h), are commonly observed in the elderly COVID-19 patients. Occasionally, thrombocytopenia (<150x109/L), higher levels of LDH (>300 U/L), D-dimers (>1.0 mg/L), and renal markers (creatinine & BUN) can be seen. Other markers indicating organ damage, such as hepatic or cardiac, are mainly within normal range. IL-6 was an underreported biochemical variable.
