Overview

Polycythemia and oxygen desaturation may be present in the patient with tetralogy of Fallot. Thrombocytopenia and deficiencies in coagulation factors may also be present.

Laboratory Findings

Oxygen Saturation

The oxygen saturation may be diminished but the pH and pCO2 are normal.

Hematocrit

The hematocrit usually ranges from 65% to 70% in patients with tetralogy of Fallot.

Platelet Count

Patients with tetralogy of Fallot may also have a low platelet count .

Coagulation Factors

Patients with tetralogy of Fallot may have lower than normal coagulation factors, including lower than normal levels of fibrinogen. The prothrombin time (PT) may be prolonged.
