The Kidneys are in the shape of beans and are placed in the upper abdominal cavity; they are on the opposite sides of each other of the spinal column. The right Kidney is a little lower than the left kidney so as to accommodate the liver. Apart from its most primary function of removing toxins and wastes from our body, the kidneys are Multifunctional.

Purpose of the Kidney Function Test (KFT)
The Kidneys are in the shape of beans and are placed in the upper abdominal cavity; they are on the opposite sides of each other of the spinal column. The right Kidney is a little lower than the left kidney so as to accommodate the liver.
Apart from its most primary function of removing toxins and wastes from our body, the kidneys are Multifunctional. Some of the major roles of the kidney are mentioned below:
- Remove waste and other fluids: We abuse our bodies’ every day by consuming various types of food and drinks in a day which puts a lot of pressure on our body, there are many of these things that the body does not require. The kidneys act as a filter to our body they help to extract all the unwanted toxins, excess salts, and urea and if the kidneys fail to do so then all the toxins start accumulating in our body which in turn damages the kidneys.
- Water level balancing: As the kidneys play a vital role in the chemical breakdown of urine, whenever there is a change in the body’s water level the kidneys start reacting, for example when there is a decrease in the water level intake of our body the kidneys start leaving water in our bodies rather than excreting it.
- Blood pressure regulation: Kidneys maintain blood pressure by regulating the volume of blood in the body. The kidneys maintain the proper levels of electrolytes (such as sodium and potassium) in the body. When electrolyte levels are high, the volume of the blood increases when the body starts retaining more water than required thus resulting in higher blood pressure. The blood pressure is maintained by kidneys by indirectly controlling the amount of blood in the body.
- Red blood cell regulation: A distress call is sent out to the kidneys when the kidneys do not get enough oxygen. A hormone called “erythropoietin” is stimulated in the bone marrow to produce more oxygen-carrying red blood cells.
- Acid regulation: As cells metabolize, they produce acids. Kidneys also help in controlling the ph levels in our bodies. Foods we eat can either increase the acid in our body or neutralize it. For the body is to function properly, we need to keep a healthy balance of these chemicals. The kidneys too.
- Keeps bones healthy: Our body and bones need vitamin D to absorb calcium and phosphorus. The kidneys also make an active form of vitamin D. In order to keep a healthy balance our body needs to function properly, cells metabolize and produce acids even foods that we eat can increase the acid in our bodies or neutralize it. The kidneys help to regulate these chemicals.
There are many causes of kidney failure, and early treatment of this disease may be the first step in correcting the kidney abnormality.
Few causes of kidney failure are treatable and the functions of the Kidney may return to normal. Unfortunately, kidney failure may be progressive in other situations and may be irreversible.
When the kidneys are not able to filter waste from the blood properly and sufficiently Kidney failure occurs. There are many factors that can interfere with the kidney’s health and function, some are mentioned below:
- toxic exposure to environmental pollutants
- certain acute and chronic diseases
- severe dehydration
- kidney trauma
Diabetes and High blood pressure: These are the two main causes of chronic kidney disease, which are responsible for up to 44% of the failure causes. Diabetes mainly causes damage to many organs in the body, including the heart and Kidney, as well as blood vessels, nerves, and eyes. Careful control of blood sugar and proper medication for high pressure can prevent kidney failure and maintain it as long as possible.
Sometimes the kidneys can stop functioning all of a sudden (within two days). This type of kidney failure is known as acute kidney failure. Few common causes of acute kidney failure include:
- Heart attack or heart disease.
- Illegal drug use and drug abuse. (especially painkillers, unprescribed medications)
- Not enough blood flowing to the kidneys may be due to infections.
- Urinary tract problems, like kidney stones, enlarged prostate, etc.
- Autoimmune diseases
- Genetic diseases (diseases you are born with), such as polycystic kidney disease
There are more than 20 million adults living with kidney disease and many do not know it. There are many physical signs of kidney dysfunction, but most of the times we attribute them to other conditions. Many people with kidney disease tend not to experience symptoms until the very late stages.
Some of the major symptoms are given below:
- Feeling more tired, weakness or are having trouble concentrating.
- Feeling cold most of the time when others are not.
- You’re having trouble sleeping.
- Shortness of breath.
- You have dry and itchy skin.
- You feel the need to urinate more often.
- You see blood in your urine.
- You’re experiencing persistent puffiness around your eyes
- Your ankles and feet are swollen.
- You have a poor appetite.
- Your muscles are cramping regularly.
Kidney disease usually does not show any early signs (a change in our body) or symptoms (a change in how we feel). The only way to know how our kidneys are doing is by getting them tested annually or half-yearly.
Mainly people with high blood pressure, diabetes, a family history of kidney disease and people older than age 60 should get their kidneys tested at regular intervals.
People who have the following symptoms or attributes should consider getting a Kidney function test done at regular intervals.
- High blood pressure
- Blood or protein in your urine with no known cause
- Cardiovascular disease (People with heart problems, arteries, and veins, such as coronary heart disease or stroke)
- Heart failure
- People with kidney stones
- People who have an enlarged prostate
- A family history of kidney disease
To test your kidney, your doctor will advise you to get the below-mentioned tests. You can get them tested individually or in a prescribed health package.
Kidney function can be tested through a basic blood test called Kidney function test (KFT) or Renal Function Test.
- A blood test checks your GFR, which tells how well your kidneys are performing and filtering. GFR stands for glomerular filtration rate.
- A urine test checks for protein and blood in the urine.
Other tests which are used for further evaluation are
- Sometimes, a CT Scan Whole Abdomen (Computerized Tomography Scan) with Contrast (for better and clearer images) is also done.
- Ultrasound of the abdomen is done to check for any abnormalities in the size or position of the kidneys or for obstructions such as stones or tumors.
- Endoscopic retrograde cholangiopancreatography (ERCP)
- Magnetic resonance cholangiopancreatography (MRCP)
A kidney function test is a blood-based test essential for the evaluation of kidney (renal) function. To test whether your kidney is working properly, your doctor will ask you to provide some blood samples. A doctor, a nurse, or a lab technician/ Phlebotomist will collect the blood sample, most probably from your arm. Usually, these tests are done early in the morning. These tests will help the doctors see how fast creatinine (the waste product) is clearing from your body. The breakdown product of muscle tissue is known as creatinine.
The report of the Kidney function test contains the normal ranges of the parameters covered. The reports of blood and urine will help you assess if more investigations are needed. Normal values for many tests are determined by the patient’s age and gender.
Your doctor may advise you to take other appropriate measures if there are any other causes of your abnormal kidney function tests, such as kidney stones and excessive use of painkillers.
If your test results show any abnormality, then you will probably need a regular kidney function test.
Your doctor will order a set of tests to test your kidney function, which can estimate your Glomerular Filtration Rate (GFR). This tells your doctor how quickly your kidneys are clearing waste from your body. It usually includes the following:
- BUN or blood urea nitrogen – this test is to check for wastes in our blood.
- Serum Creatinine – this test examines whether creatinine is building up in your blood. A high level suggests a kidney problem.
- Glomerular Filtration Rate (GFR)- The test determines the rate by looking at factors, such as age, gender, race, height, weight.
- Electrolytes (Potassium & Sodium).
- Chloride in blood & urine.
- Creatinine clearance.
- Protein in the urine.
- Urine analysis
- 0.6 to 1.2 milligrams per deciliter in adult males
- 0.5 to 1.1 milligrams per deciliter in adult females.
- 20-40 mg/dL
- 3.5-5.5 mEq/L
- 135-147 mEq/L
- 9-11 mg/dL
- 98-106 mEq/L
