Kidney tests and their procedure

Kidney health is the cornerstone of your overall well-being. Most importantly, it helps in waste elimination from the body and keeps all the water & nutrient levels to be in a suitable space. If you are struggling with kidney-related issues, then it’s imperative to keep a check over its entire state by visiting the Kidney Hospital. When there’s a kidney problem, you need to be sure that you are following every possible measure to keep a check on your kidney health. The doctor will ask you to undergo kidney tests to determine what’s wrong and how everything can be well-managed to better analyze your condition.

Types of kidney function

If it seems like there’s some problem, then your Urologist in Ludhiana is going to tell you better about which type of test you should get to determine the exact problem:

  • Urinalysis

Urinalysis is the test to check the blood and protein amount in the urine. Although, protein presence is likely the reason for different cases like infection, heavy physical workout, and others. The doctor will ask you to get additional tests after a few weeks to see if the results are the same.


  • Serum creatinine test

A serum creatinine test is the best way to analyze creatinine levels in the blood. The kidneys are accountable for getting it checked from blood. If the creatinine level comes out to be higher, then there are increased chances you have kidney problems.


  • BUN (Blood Urea Nitrogen)

BUN is another kidney test done to check the presence of waste content in blood and nitrogen. Although not at all times, the elevated level of BUN signals kidney problems. At times when there is excess intake of medication like aspirin even then, BUN is likely to increase. At times, the reason for its increase can suggest there’s a health issue.


  • Estimated GFR

Estimated GFR (Glomerular filtration rate) tells about the kidney performance in filtering waste. Under this test, different factors are considered to well analyze what’s wrong like:

  • Age
  • Gender
  • Race
  • Height
  • Weight
  • Test results (Creatinine level)


How are kidney tests performed?

A kidney test is done by doing 24-hour urine samples and a blood test. Here’s what happens with both of these:

  • 24-hour urine sample

A 24-hour urine sample plays a major role in checking creatinine levels in the body. On the day of your test, you need to collect a urine sample in the morning. Now, for the rest of the day and the entire night, you need to collect the sample in the tightly capped container. Make sure to keep it in a cool place and preferably label it. When you get up the next morning, collect a urine sample again and then drop it off at the clinic.


  • Blood sample

A blood sample is another test done like a normal blood test. The blood sample is collected and then sent to the lab to determine if something is wrong.
