Kidney Function Test (RFT) in Gujranwala

Here is the uncomfortable fact about kidneys: you can lose a large share of their function before you feel anything at all. No pain. No obvious symptom. By the time swelling in the ankles or persistent tiredness sends someone to a doctor, the damage has usually been accumulating for years.

A Renal Function Test, also called a Kidney Function Test or RFT, measures how well your kidneys are filtering waste from your blood, balancing your body’s salts and water, and helping control blood pressure.

Doctors order it for diabetes, the leading cause of kidney failure, for high blood pressure, for swelling of the feet or face, for changes in urination, for persistent tiredness without another explanation, before starting certain medicines, for long-term painkiller use, for a family history of kidney disease, and as part of routine annual screening.

For anyone in Gujranwala living with diabetes or high blood pressure, this is the test that catches kidney damage early enough to act.

What's Included

Serum Creatinine

A waste product cleared entirely by the kidneys
The central number on the panel; rises when filtering slows

Blood Urea / BUN

Another waste product, from protein breakdown
Read alongside creatinine rather than alone

eGFR

Estimated Glomerular Filtration Rate, calculated from creatinine, age and sex
The number nephrologists use to stage kidney disease

Sodium and Potassium

The electrolytes your kidneys balance
High potassium can affect heart rhythm and need urgent attention

Chloride and Bicarbonate

Complete the electrolyte and acid-base picture

Uric Acid

Commonly requested alongside a renal panel
High levels cause gout and are linked to kidney stones

How to Prepare

  • No fasting is required for a kidney function test on its own. If it has been ordered alongside a lipid profile or fasting blood sugar, follow the fasting rule for those and book a morning slot.
  • Drink water normally in the days before. Do not deliberately over-hydrate or under-hydrate, since dehydration raises urea and creatinine and produces a falsely worrying report.
  • Avoid a very high-protein meal the evening before, including large quantities of red meat, as it can temporarily raise urea.
  • Avoid heavy exercise for 24 hours. Intense activity releases creatinine from muscle and can push the value up independently of your kidneys.
  • List all your medicines. NSAIDs, certain antibiotics, blood pressure medicines and diuretics all affect these numbers.
  • Mention any recent contrast scan. Contrast dye used in CT scans temporarily affects kidney values.

Frequently Asked Questions

No. A kidney function test on its own does not require fasting. If your doctor has combined the RFT with fasting blood sugar or a lipid profile, follow the 9 to 12 hour fasting rule for those and book a morning slot.
Renal panels receive a same day report, since samples are processed at our own laboratory in Model Town rather than being sent elsewhere. Reports arrive by WhatsApp and are available in the City Care Lab app.
Yes, free of charge across Gujranwala, Daska, Sambrial and Mundeke. This is a common request for elderly patients and for people on regular chronic disease monitoring. WhatsApp 0316-7208633 with your address and the test required.
Yes. Diabetes is the most common cause of kidney failure, and early diabetic kidney damage produces no symptoms whatsoever. Regular monitoring allows treatment to slow the damage while there is still function worth protecting.
