Consideration of leukemia or undiagnosed sickle cell disease
Type and screen
May require exchange transfusion in sickle cell disease
Coagulation profile
Consider urinalysis/toxicologic screen if unclear etiology
Cavernosal blood gas may help differentiate high- from low-flow
Low flow causes hypoxic, hypercarbic, and acidotic cavernosal blood gases
pH < 7.25, pO2 < 30 mmHg, pCO2 > 60 mmHg
Ultrasound may help distinguish high- from low-flow
