Kidney Function Test
Kidneys are indeed very important for the excretion process in a human body. They form a vital part of your urinary tract, helping you in filtering out the wastes from your body, maintaining healthy body water and mineral levels and production of vitamin D, hormones that regulate blood pressure and red blood cells.

Types of Kidney Function Tests
Doctors judge the condition and give their prognosis based on different parameters associated with your kidneys. To analyze those parameters, there are majorly seven types of kidney function test listed out below.
This test is majorly done to detect the presence of protein and blood in urine. There are many possible reasons for protein in your urine, all of which might not be leading to diseases. For instance, infection increases urine protein, but so does a heavy physical workout. This can help doctors differentiate by seeing how fast creatinine is clearing from your body.
Serum Uric Acid
Serum Uric acid test is to detect high levels of uric acid in the blood, which could be subsequently leading to gout. Uric acid forms crystals or kidney stones that can damage the kidneys. When you feel extremely painful at the lower end of your abdomen, there are chances you might have gout and therefore, your doctor might recommend you take this test.
There are two common causes of kidney failures: pre-renal (dehydration) and tubular death (ATN). The serum sodium test helps distinguish between the two. Your doctor may order the urine sodium test if you get abnormal results on a sodium blood test, which can indicate to acute kidney failure.
Urine potassium test may be the next step for people with abnormal blood potassium levels to help determine the cause, such as dehydration. If you have an abnormal kidney problem but the medical professional cannot figure out what it is, he may use a serum potassium test to come to a diagnosis.
People with the condition proteinuria have unusually high amounts of protein in their urine. This condition is a red flag for a kidney disease. Your kidneys strongly filter out a lot of proteins and keep them from flowing into the blood. When kidney disease damages them, proteins such as albumin may leak from your blood into your urine.
Serum creatinine test
This blood test is for determining whether creatinine is building up in your blood. The kidneys under normal circumstances, completely filter creatinine from the blood. If you have high levels of creatinine, you are likely to have a kidney problem. The National Kidney Foundation (NKF) has set predefined levels which are normal. That means, a creatinine level higher than 1.2 milligrams/deciliter (mg/dL) for women and 1.4 mg/dL for men is not normal.
Blood urea nitrogen (BUN)
The blood urea nitrogen (BUN) test checks for useless, trash products in your blood. It is also responsible for measuring the amount of nitrogen in the blood. It measures Urea nitrogen which is a breakdown product of protein. A higher value than 20 mg/dL could mean something is wrong, suggesting several different health problems.
The GFR test estimates the accuracy of your kidneys when it comes to filtering waste. The test determines the rate by looking at numerous factors, such as: test results, specifically creatinine levels, age, gender, race, height, weight. The normal value for a result is 60 milliliters/minute/1.73m2 and anything lesser is trouble invited.
ACR (Albumin to Creatine ratio)
This 24-hour urine sample, creatinine clearance test, gives your doctor an idea of how much creatinine your body throws out every single day. On the day of commencement of the test, you pass your first urine normally like every other day. For the rest of the day and night, you urinate into a container provided by the lab. You have to keep the container capped and refrigerated. On the morning of the second day, again urinate into the container when you get up. This completes the 24-hour collection process. All you have to do is drop the sample off and wait for the lab to contact you once the tests are done.
GFR (Glomerular Filtration rate)
BUN and serum creatinine tests are the ones which require you to take blood samples to a lab or doctor’s office. The assistant first ties an elastic band around your upper arm to highlight the vein. They sterilize the area and slip a hollow needle through your skin and into the vein. The blood will collect in test tube and will be sent for analysis. The assistant will place gauze and a bandage over the puncture site after the test. You might notice the area around the puncture look bruised over the next few days, but it shouldn’t feel severe. The reports will be out in a day or two.
Symptoms of Kidney Problem
You may need to take a kidney function test if you show the following symptoms:
- Brown or bloody urine
- Difficulty urinating
- Infrequent urination
- Swelling due to accumulation of body fluids
- Severe pain or cramps
- Excessive fatigue
- Shortness of breath
- Abnormal sleep schedule
- Itchy skin
- Low appetite
In the case of children, symptoms of kidney disease may be feeling worn out and sleepier than usual, having less appetite than normal, and not be growing as expected.
Causes of Kidney Problems
Kidney diseases are silent killers; you won’t know before they damage you. Therefore, it is important to know the causes of these diseases and take precautions accordingly or if you can’t help it, at least be prepared. Here are some major causes listed down:
High Blood Pressure
The two leading causes of kidney failure are diabetes (also called Type 2, or adult-onset diabetes) and high blood pressure. These are also called end stage kidney disease or ESRD. When these two diseases are controlled by treatment and healthy lifestyle changes, the associated kidney disease can often be prevented or slowed down.
Maintain nominal blood sugar levels in diabetes helps to prevent such complications as kidney disease, coronary heart disease and stroke. When diabetics have associated high blood pressure, you might have to shift to special drugs called angiotensin converting enzyme (ACE) inhibitors responsible for protecting your kidney function.
Understanding your family health history is an important step in knowing your risk for kidney disease. Almost all the cases are hereditary that is, if someone else in your family has it, you are more likely to get it.
Life is risky in all aspects when you are over 60. But pertaining to kidney function, your risk for kidney disease also shoots up. With age, your kidneys start to underperform. People age 60 or older also develop diabetes and high blood pressure, which as discussed earlier, are the two leading causes of kidney failure.
Infections, kidney stones and inherited diseases such as polycystic kidney disease, glomerulonephritis, etc. are some other problems which can deteriorate kidneys. Damage can also be due to some over-the-counter pain killers and by taking illegal drugs such as heroin. While some of these diseases can be cured, in other cases treatments can help to slow the disease and prolong life.
Kidney Function Test Cost with Procedure
Kidney function tests cost approximately around Rs 900-500 in India, even in prime cities like Delhi. You might find cheaper tests but most unlikely above the mentioned price, anywhere in India. Before you step into this, you need to know what you will have to go through i.e., how the tests are performed.
