*Biochemistry,hematology and Thyroid function tests are required in all patients with pulmonary hypertension.(Important for diagnosis of [[chronic hemolytic anemia]], [[myeloproliferative disorder]]s, thyroid disorders and [[chronic renal failure]] on [[dialysis]]).
*Biochemistry,hematology and thyroid function tests are required in all patients with pulmonary hypertension.(They are important for the diagnosis of [[chronic hemolytic anemia]], [[myeloproliferative disorder]]s, thyroid disorders and [[chronic renal failure]] on [[dialysis]]).
* Serologic testing to detect Connective tissue diseases([[systemic sclerosis]]), [[HIV]] and [[Hepatitis]].
* Serologic testing to detect connective tissue diseases([[systemic sclerosis]]), [[HIV]] and [[Hepatitis]].
'''[[Systemic sclerosis]]''' is very important to exclude in pulmonary hypertension because this systemic disease has a very high prevalence of pulmonary arterial hypertension. [[Anti-Scl-70]], [[anti-centromere]], and [[U3-RNP]] are typically positive.
**[[Systemic sclerosis]] is very important to exclude in pulmonary hypertension because this systemic disease his risk factor for the development of pulmonary arterial hypertension. [[Anti-Scl-70]], [[anti-centromere]], and [[U3-RNP]] are typically positive.
*Liver function tests to exclude [[portal hypertension]].
*Liver function tests should be done to exclude [[portal hypertension]].
*Both ANP and BNP have been shown to correlate with the survival in [[Idiopathic Pulmonary Hypertension]]. However NT-proBNP appears to be an independent predictor of survival and correlates with RV dysfunction.
*Both ANP and BNP have been shown to correlate with the survival in [[Idiopathic Pulmonary Hypertension]]. However NT-proBNP appears to be an independent predictor of survival and correlates with RV dysfunction.
*Serum [[uric acid]]: reflects impaired [[oxidative]] metabolism of [[ischemic]] peripheral tissues..
*Serum [[uric acid]] is measured as it reflects an impaired [[oxidative]] metabolism of [[ischemic]] peripheral tissues.
