Table 1 Recommended investigations for COVID-19

From: Rapid guide to the management of cardiac patients during the COVID-19 pandemic in Egypt: “a position statement of the Egyptian Society of Cardiology”

CBC Leukopenia, leukocytosis, and lymphopenia
CRP Elevated
Lactate dehydrogenase and ferritin Elevated
Liver enzymes: SGOT, SGPT Elevated
Urea, creat Elevated
PT, PTT, INR Elevated
D dimer Elevated
C&S May be bacterial infection
Cardiac enzymes ELEVATED
CXR may reveal pulmonary infiltrates
Nasoharyngeal swab for PCR.
The test is a real-time reverse transcription-polymerase chain reaction (rRT-PCR) assay that can be used to diagnose the virus in respiratory and serum samples from clinical specimens.
The highest rates of positive results included BAL fluid (14/15; 93%), sputum (75/104; 72%), nasal swabs (5/8; 63%), brush biopsy (6/13; 46%), pharyngeal swabs (126/398; 32%), feces (44/153; 29%), blood (3/307; 1%), and urine (0/72; 0%). Nasal swabs were found to contain the most virus.
CT CHEST Peripheral distribution (80%)
Ground-glass opacity (91%)
Fine reticular opacity (56%)
Vascular thickening (59%)
Central and peripheral distribution (14%)
Pleural effusion (4.1%)
Lymphadenopathy (2.7%)
ECG Ischemia, arrhythmias, conduction delays
