Table 1 Recommended investigations for COVID-19
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 |
ABG | HYPOXIA |
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 |
ECHO | Diastolic dysfunction LV systolic dysfunction Myocarditis, endocarditis, pericarditis |
