Blood tests help us detect early and hidden problems, and reduce uncertainty by helping us make the best treatment decisions for you.
The most common laboratory blood tests we use to check for heart conditions are:
it measures the types and numbers of cells in your blood, e.g. red blood cells, white blood cells and platelets. Abnormal results might suggest reduced oxygen levels, decreased immune response or impaired blood clotting.
it measures kidney function, protein levels, electrolytes like sodium and potassium and other important minerals. These substances are important for the overall function of your heart.
it measures the levels of triglycerides, cholesterol and gives you a breakdown of the “good” and “bad” cholesterol
- Clotting screen: it measures how long it takes for your blood to clot. It is an important test if you take the blood thinning medication Warfarin. Also, if your liver isn’t working well, your blood won’t clot properly.
- Liver profile: it measures the liver’s function which affects how the body processes medication. A liver that doesn’t function well can affect the heart, too.
- BNP or NT-pro BNP: it’s a heart function test and the most important blood test in diagnosing heart failure.
- Troponin: a heart test for a “heart blockage”, i.e. it helps diagnosing or excluding a heart attack.
- Thyroid function test: an underactive or overactive thyroid gland can affect the heart’s function causing palpitations or slow and fast heart beats.
