What are the tests for pulmonary hypertension?

PH evaluation. The conclusive diagnostic test for PAH is a right heart catheterization to measure pulmonary artery pressures and cardiac output. The diagnosis may be supported by physical findings, blood tests, chest x-rays, electrocardiograms, echocardiograms, pulmonary function tests, exercise tolerance tests (six-minute walk tests) and nuclear scans (ventilation/perfusion scan), but these tests may be negative or only suggestive of the diagnosis.
Many. There are several tests that a patient goes through to confirm primary pulmonary htn. The process usually begins with an ultrasound of the heart (echocardiogram) to identify high pressure. Other test will include lung function tests, test for blood clots, blood test for a variety of diseases and ultimately a right heart catheterization must be done.
Various. The definitive test is a right sided heart catheterization and this is required to diagnose the disease. Other tests may help as well such as echocardiogram or walking tests but you cannot diagnose pulmonary hypertension without a heart cath.

What are the diagnostic tests to know the cause of my moderate pulmonary hypertension?

Many tests: RHC most. Many tests are undertaken in the workup for pulmonary hypertension. The usual starting tests are an echocardiogram (ultrasound of the heart) for valve problems / leaks & "6-minute walk test" for activity tolerance. Pulmonary function tests (PFT) & Cardiopulmonary stress tests may also be needed. The MOST IMPORTANT test, though, is the right heart cath (RHC) which is invasive. TTYD or Cardiologist.

I lost my child due to pulmonary hypertension. Is there any test to diagnose this inside my womb?

Prenatal testing. If it is an isolated finding, and there are no other abnormalities in the heart, pulmonary hypertension can't be seen prenatally.

Are there tests to confirm the doctor's diagnosis of primary pulmonary hypertension?

Yes. The diagnostic gold standard is a "right and left" heart catheterization. Tubes (catheters) are guided into 1 artery and 1 vein and pressure measurements are made in each chamber of the heart, the pulmonary artery, and pulmonary capillary bed. If pph is confirmed, drugs are immediately given to test if they are effective in lowering the pressure. A search should also be done to look for a cause.
Echo and cath. Echocardiogram is a good noninvasive tool to evaluate pulmonary hypertension. A right heart cath is a more direct and precise way of measuring pulmonary artery pressure and assesss response to treatment.

Is it possible to have pulmonary hypertension without any lung disease? My tests suggest I have moderate ph. My cadiocath also

Yes. Majority of pulmonary hypertension are idiopathic or of unknown cause.
Yes. I gather from your meds that you've either had a transplant or have vasculitis. Vasculitis can cause pulmonary htn. The commonest cause of phtn is congestive heart failure from any cause including valvular disease, cardiomyopathy, and intracardiac shunts.. Primary (or idiopathic) pulmonary HTN also is a possibility but it's thankfully relatively rare.

Is a Octostim (DDAVP) test for bleeding issues contraindicated in a patient with mild pulmonary hypertension requering notreatment?

Test with caution. DDAVP (desmopressin) is contraindicated in patients with known allergy, kidney failure or low sodium levels. It is known to cause fluctuations in your BP and a decrease in sodium levels. It should be used with caution in patients with cystic fibrosis, heart failure as they are prone to sudden drops in sodium. If your pulmonary hypertension is not related to any of the above, then you can proceed with caution.
DDAVP. Would you please clarify the question: dDAVP is a medication that is used in patients with diabetes insipidus and is also used for certain types of bleeding disorders. Are you referring to the use of a medication or a certain test?

Can a tilt-table test plus the adrenaline shot cause problems to patients with pulmonary hypertension?

TTT Pulm HTN. A TTT assesses how your BP/HR responds to standing. Adrenaline is normally released in response to standing to raise the HR. It could have a vaso constrictor effect on pulmonary circulation. Guazzi MD, De Cesare N, Fiorentini C, et al. Pulmonary vascular supersensitivity to catecholamines in systemic high blood pressure. J Am Coll Cardiol. 1986;8 (5):1137-1144. doi:10.1016/S0735-1097 (86)80393=.

I'm being checked for pulmonary hypertension as well. Is tht caused by clot history or lupus? I have so many test coming ana, dsdna, sleep o2 level

See below. Pulmonary hypertension can caused by several things such as autoimmune disease such lupus as well as clots. However; diseases such as obstructive sleep apnea can have it as well. Continue the workup that you are undergoing.
Both. Both lupus and clot history put you at risk for pulm htn.
Testing. Given your history of joint pain, hypertension, fatigue and skin rash, I would also suggest that you have a urinalysis and renal function testing. The symptoms that you are describing may be caused by a number of different conditions. Your physicians are trying to diagnose and rule out some causes. Once the testing is completed, I would suggest scheduling an appointment to review all the results.

Can chest xrays see pulmonary hypertension? What about CT of chest? Or stress tests on treadmill

Yes. Pulmonary hypertension causes enlargement of the pulmonary arteries, which can be seen by xray, but better seen by ct. However, pulmonary arteries can be enlarged without hypertension.
No. There are clues on cxr and chest ct, but the real way to diagnose it non-invasively is with echocardiography. The definitive way is by heart catheterization.
