Is there a blood test that can diagnose pulmonary oedema or pulmonary embolism?
Asked by Female, 45 · 2 months ago
Pulmonary oedema (fluid buildup in the lungs) cannot be diagnosed from a blood test alone. It is usually diagnosed using imaging tests, such as a chest X-ray or an echocardiogram. Pulmonary embolism (a blood clot in the lungs) may be suspected with a D-dimer blood test, but confirmation requires imaging, such as a CT pulmonary angiogram. Both conditions can be serious, so if you experience sudden shortness of breath, chest pain, or a rapid heartbeat, seek immediate medical attention.

Pulmonary Oedema Diagnosis:
- Primarily diagnosed through clinical evaluation and imaging like chest X-rays.
- Blood tests may help identify underlying causes such as heart failure.
Pulmonary Embolism Diagnosis:
- Blood tests like the D-dimer test can suggest the presence of blood clots.
- A positive D-dimer indicates the need for further imaging tests, such as CT pulmonary angiography or ventilation-perfusion scans, to confirm PE.
General Advice:
- Blood tests alone cannot definitively diagnose these conditions.
- Seek prompt medical evaluation if you have symptoms suggestive of these conditions for appropriate testing and treatment.
