Urea and electrolytes blood test provide essential information regarding renal functions. We can also have an idea about disturbed homeostasis and excretory functions. The levels of sodium, potassium, and magnesium are checked by these tests. By these tests, health care professionals analyze the types of diseases in the body. Greater and lower levels of these chemicals suggest the malfunctioning of certain systems of our body. The reports of these tests can tell us about the underlying diseases and imbalances. This article will help you understand why these tests are done and how the reports help us in diagnosing diseases: 

Importance of Urea and Electrolytes Blood Test

Homeostasis is a self-regulatory mechanism with the help of which an organism maintains its stability to its surroundings. It can be disturbed easily. There are many reasons for the instability of this process. The most common reason is the disturbance in the levels of chemicals and electrolytes. These chemicals are important for the maintenance of our normal body functions. They are harmful if their levels increase or decrease. These chemicals are also known as electrolytes. 

Our bodies make a protein named Urea. It is usually broken down in the kidneys. If the levels of Urea in our blood suddenly get higher, it shows a problem with kidney functions and this can be only detected with urea and electrolytes blood test. Some people who are taking medications such as ACE Inhibitors can affect kidneys too. These tests will help your doctor to decide wisely to increase or decrease your dose. Some of the conditions mentioned below are caused by high or low levels of electrolytes. These tests are immediately needed when a patient comes with these conditions.

Urea And Electrolytes Blood Test For Hyponatremia

It is a condition caused by the extremely low levels of sodium in the body. Sodium is the most important electrolyte in the body. It maintains the amount of water in our bodies. Hyponatremia suggests an underlying disease. In this condition, the patient consumes too much water. Drinking too much water causes the sodium to get diluted. Its concentration in the blood decreases. The water level rises and can cause swelling of the tissues. This swelling can be dangerous. It can cause serious health problems. Patients with hyponatremia have the signs and symptoms of nausea, vomiting, restlessness, muscle weakness, seizures, irritability, and confusion. 

Doctors will suggest you get your tests done for electrolytes urgently. It is important to diagnose the main cause of this condition. It can be related to many medical conditions. Sometimes patients are taking medicines such as antidepressants, diuretics, and pain killers. The patient can also have heart, kidney, and liver problems. A congestive heart failure is also caused by the low levels of sodium in the body. These tests help the health care professionals to evaluate the main cause of the symptoms. 

Hypernatremia

Another medical condition where sodium levels increase in the body is termed hypernatremia. Sodium, no doubt, is an important electrolyte for our bodies. But the excessive levels of sodium can cause serious health problems. Because of too much sodium in the blood, the patient drinks lots of water. These tests are done to know the exact levels of sodium in the blood. If a person has not enough water intake, their sodium levels will get high. They will feel excessive thirst. This can be dangerous for the kidneys. It can also cause edema. 

Brain dysfunction can also be seen in hypernatremia. If the condition gets worse, it can cause muscle twitching, confusion, and comma. In severe cases, it may be life-threatening as well. The diagnosis is based on blood tests. If the levels of sodium are high in the blood, the patient has hypernatremia. Doctors do confirmative testing of the measurements of urine as well. Fluid replacement therapy is done to treat this condition. The levels of sodium are reduced in the body slowly. If it is done rapidly, the person can get severe brain damage. 

Hyperkalemia

If these tests show increased levels of potassium in your body, it means you have hyperkalemia. It is definitely an important nutrient present in our body. It helps your nerves and muscles. It is useful for the normal working of the heart as well. But as we all know that excess of everything is bad. Increased levels of potassium are damaging to your body. Hyperkalemia suggests that your kidneys are not working right. Kidneys balance the amount of potassium in our bodies. 

In many renal diseases, kidneys start making high potassium. But eventually, they fail to filter it out from the body. Hyperkalemia is also seen in chronic kidney disease. The accurate way to know about the high levels of potassium in your body is to get your tests done. Symptoms of hypernatremia are usually non-specific. They include tingling sensation, nausea, and other unusual feelings. It is important to get your tests done as soon as possible for a better prognosis.

Renal Impairment

These tests are important in letting doctors know about the functionality of kidneys. Kidneys have the function of filtering Urea and other electrolytes from the body. If, in any case, these levels are increasing or decreasing, it shows that the function of the kidney is impaired. Symptoms of kidney impairment include shortness of breath, dehydration, nausea, confusion, and muscle weakness. Urea is synthesized by the liver. It is a good marker of kidney diseases. Increased levels of Urea indicate dehydration, heart failure, gastrointestinal bleed, and renal failure as well. Levels of Urea also seem to be elevated in the urinary tract obstruction. It is important to get these tests done to have a clear picture of the functions of the kidney. Similarly, decreased levels of Urea indicate liver diseases, increased water uptake, and malnourishment. 

Urea and electrolytes blood test is important in detecting the levels of important electrolytes in our bodies. These are the most commonly required tests by doctors. They help in providing a clear picture regarding renal functions and excretory mechanisms. These tests are required for the diagnosis of acute kidney injury and chronic kidney diseases. It is essential to get these tests done on the doctor’s recommendation to avoid life-threatening illnesses.
