If you have been diagnosed with high blood pressure, or if you are told you are at risk of developing high blood pressure, there is an important blood test that your doctor will tell you to help monitor high blood pressure. The tests will identify nutritional deficiencies that may cause endothelial dysfunction and arterial stiffness. These two factors not only increase the risk of developing high blood pressure, but also the reason why blood pressure is very difficult to treat. This test is also important to evaluate other organs in the body that can be affected by blood pressure.
Laboratory examinations and other investigations are not always performed unless you suspect the presence of secondary hypertension. Examination includes examination of urine and blood tests. Urine examination is performed to determine the presence of proteins and red blood cells (erythrocytes) that indicate kidney damage. Sugar levels to detect diabetes also should be checked. Blood tests performed to determine kidney function, including measuring levels of urea and creatinine. Potassium levels in the urine will be high if there is primary aldosteronisme disease, because adrenal gland cortex tumors that can trigger hypertension. High levels of calcium are associated with hyperthyroidism. Through this examination, blood sugar and cholesterol levels are also measured.
There are many other types of checks that can be done to support the diagnosis of hypertension. Examination of chest and heart record (EKG), ultrasound examination (USG), and Magnetic Resonance Angiography (MRA) is performed to see the smooth flow of blood.
Complications of hypertension occur because of increased blood pressure that damages the target organs. To find out whether there is a complication then you should do a variety of checks ie eyes, heart, kidneys, and brain.
To detect abnormalities of organs or blood vessels, usually examination of the retinal blood vessels. This is based on the assumption that the changes that occur in the retina are similar to changes that occur in other blood vessels in the body, such as the kidneys. By determining the degree of retinal damage, it can be determined the severity of hypertension.
Changes in the heart, especially heart enlargement, can be detected by electrocardiography (ECG) and chest x-rays. In the early stages, these changes can be found through echocardiography. Abnormal heart sound can be heard through a stethoscope and is the earliest heart changes that occur due to high blood pressure.
Initial guidance of kidney damage can be known primarily through urine examination. The presence of blood cells, sugar and albumin (a type of protein) in the urine can be an indication of kidney damage.
To find out other causes can be done certain routine examinations, such as measuring the levels of potassium in the blood can help find a state of hyperaldosteronism. Low blood potassium levels indicate the likelihood of an overactive adrenal gland. And measuring the difference in blood pressure in both arms and legs can help find a major arterial abnormality.
