Labs:
CBC: Leukopenia, thrombocytopenia, and hemoconcentration

DIC labs should be sent
Diagnose by 4x increase in acute/ convalescent titres - unlikely to be resulted in ED
Tourniquet Test - Tests capillary fragility
Sensitivity of 52% and specificity of 82.4%
A positive tourniquet test combined with lekuopenia increases sensitivity to 94%
Inflate cuff to pressure between SBP & DBP, and leave for 5 min
(+) Test = 10-20 petechiae per square inch
