Hypertension Blood Test

Once diagnosed as hypertension, then it is suggested to diagnose the reason behind the cause of hypertension.

Common blood test for hypertension

• Creatinine (renal function) - to identify both underlying renal disease as a cause of hypertensive and conversely hypertensive causing onset of kidney damage.
• Electrolytes (sodium, potassium)
• Glucose - to identify diabetes mellitus
• Cholesterol
• Heart tracing (an electrocardiogram, also called an ECG).

Purpose of hypertension blood tests

• Diagnose or rule out a secondary cause of high blood pressure such as kidney disease.
• Check whether the high blood pressure has affected the heart.
• Check risk factors such as a high cholesterol level or high blood glucose level (diabetes).
