Breathlessness and palpitations in otherwise healthy people are frequently caused by anaemia (low haemoglobin) or an overactive thyroid. A CBC with iron studies and a thyroid test cover these common causes.
These symptoms can occasionally point to heart or lung conditions, so if they are severe, sudden or with chest pain, seek medical care promptly rather than waiting for tests.
4 curated lab tests — your doctor decides which you actually need.
Yes. Low haemoglobin reduces oxygen delivery and commonly causes breathlessness and palpitations, which is why a CBC with iron studies is a first test.
An overactive thyroid (hyperthyroidism) can cause palpitations and breathlessness; a thyroid function test screens for it.
Sudden or severe breathlessness, chest pain or fainting needs urgent medical care — do not wait for lab tests in those situations.
