High blood pressure tests are not that many. High blood pressure is also known as hypertension.

The best and fastest way to know if your BP is high is to measure it. An instrument called a sphygmomanometer or blood pressure monitor is used.

BP is measured manually with a sphygmomanometer digital or electronic monitors. Your health care provider will measure the BP and determine if it’s normal or high.

You can also measure your own BP at home when you buy one of these monitors. You can have your BP measured for free in many countries at pharmacies and some big supermarkets.

Of all the high blood pressure tests, measuring your BP is the easiest and fastest test you can do.

The normal blood pressure is below 120/80. However, in some patients, blood pressure may temporarily go up in the presence of a doctor. This is called white-coat hypertension.

Diagnosis of high blood pressure

Blood pressure that is consistently above 140/90 is considered hypertension.

BP fluctuates during the day and night, depending on activity level. Before measuring your BP, make sure you are relaxed and rested.

Doctors will diagnose hypertension when your BP is higher than 140/90 on three separate occasions.

In some instances, the diagnosis will be made right away if the BP is severely high and there is evidence of organ damage.

Doctors will also make history taking to access risk factors of hypertension like any symptoms, family history, alcohol intake, smoking habits, diet, any diseases like diabetes and cholesterol, and other causes of high blood pressure.

An examination may also reveal other signs of chronic hypertension like swollen legs and abdomen, papilloedema in the eyes, and other signs.

Tests for High Blood Pressure

Health practitioners will also want to rule out risk factors of HBP and secondary hypertension by doing tests.

These tests for high blood pressure are;

Blood tests

High blood pressure tests will include blood tests like;

Complete Blood Count (CBC or FBC)
Urea (Blood Urea Nitrogen, BUN)- to check for kidney function
Electrolytes- like potassium sodium to exclude causes of secondary hypertension
Blood glucose level- to check for diabetes mellitus
Cholesterol level

Urine tests

High blood pressure tests will include urine tests like;

Blood in urine
Protein – to check for kidney function and damage

Heart Function

These tests will include checking the heart function using;

Electrocardiogram (ECG or EKG)- to check for heart rhythm and signs of heart disease.
Holter monitor- this is a portable EKG machine.
Echocardiogram- to check the size of heart chambers and their function
Stress tests- like exercise to determine how much a person can tolerate activity without having chest pain or abnormal blood pressure.
