Extended blood tests	Electrolytes (signs of hyponatremia), glucose, vitamin D, SarsCoV-2 IgG
	Full blood count (signs of Lymphopenia, neutrophilia, thrombocytopenia)
	Inflammatory markers: procalcitonin, IL-6, ferritin, CRP, erythrocyte sedimentation rate
	Cardiac enzymes: Pro-BNP, trop-I, CK-MB, CK
	creatinine, BUN, uric acid, GOT, GPT, GGT, AP, cholinesterase, lipase, bilirubin, albumin, total protein, LDH
	Coagulation tests (including fibrinogen, D-dimer)
Microbiological testing	Blood culture, urine culture, stool culture, PCR for respiratory viruses and cultures of a throat swab
Mandatory diagnostic procedures	12-channel ECG and echocardiography
Conditional diagnostic procedures	Chest X-ray, abdominal ultrasound
Vital signs monitoring	ECG, O2 saturation, and non-invasive blood pressure control.
