Laboratory Investigation

• A complete blood (CBC) count, biochemistry panel, prothrombin time (PT), and activated partial
thromboplastin time (aPTT)

• Arterial blood gas determinations to assess for hypoxemia.

• Collagen-vascular disease screening can be performed by measuring antinuclear antibody (ANA)
levels

• Liver function tests, as well as markers of synthetic function (ie, albumin, international normalized
ratio [INR]), and platelet levels may indicate liver disease and/or portal hypertension.

• In patients at risk for heritable pulmonary arterial hypertension (PAH), screening for gene
mutations such as BMPR2 also may be considered.

• Iron studies - patients with idiopathic PAH (IPAH)
