Basic laboratory tests on admission were significant for hyponatremia (hypervolemic hyponatremia from tamponade physiology and acute renal failure), acute kidney injury, leukocytosis with lymphopenia (associated with COVID-19 infection), mildly macrocytic anemia in setting of alcohol use disorder, and coagulation panel within normal range apart from elevated d-dimer (seen in patients with COVID-19); serial troponin draws were negative.
