Renal Function Tests (RFTs) are blood and urine tests used to check how well your kidneys are working. They measure waste products like creatinine and urea, calculate eGFR, and assess electrolyte balance. In Pakistan, the RFTs test price is around PKR 2,000, and results are usually available within 24–48 hours. RFTs help detect kidney disease early, especially in people with diabetes or high blood pressure.
What Is an RFTs Test?
Renal Function Tests (RFTs) evaluate the kidneys’ ability to filter blood, remove waste, balance fluids, and regulate minerals. Because kidney disease often has no early symptoms, RFTs are one of the most reliable tools for early detection and monitoring.
Doctors commonly recommend RFTs for routine screening, diagnosis of kidney problems, and follow-up of chronic conditions.
RFTs Test Price in Pakistan
| Test | Price (Approx.) |
|---|---|
| RFTs Profile | PKR 2,000 |
| Urine R/E (if required) | PKR 650 |
| Microalbumin (optional) | PKR 1,500 |
Prices may vary slightly depending on additional parameters such as electrolytes or minerals.
What Tests Are Included in RFTs?
A standard RFTs profile may include:
- Serum Creatinine – Indicates kidney filtration efficiency
- Blood Urea Nitrogen (BUN) – Measures waste removal
- eGFR (Estimated Glomerular Filtration Rate) – Stages kidney function
- Uric Acid – Related to kidney and metabolic health
- Electrolytes (Sodium, Potassium, Chloride)
- Calcium & Phosphorus
- Urine R/E or Microalbumin (if advised)
RFTs Test Procedure (Step-by-Step)
1. Appointment or Walk-In
You can book an appointment or visit the lab directly during working hours.
2. Test Preparation
- Fasting for 8–12 hours may be advised
- Drink water normally
- Avoid heavy exercise before testing
- Inform the lab about medications
3. Sample Collection
- Blood sample taken from a vein
- Urine sample if included in the profile
4. Laboratory Analysis
Samples are analyzed using automated diagnostic analyzers under quality-controlled conditions.
5. Report Collection
- Reports are available within 24–48 hours
- Can be received via WhatsApp, Email, or physical copy
How to Read RFTs Results
- High Creatinine: Reduced kidney filtration
- Low eGFR: Decreased kidney function
- High Urea/BUN: Kidney dysfunction or dehydration
- Electrolyte Imbalance: Risk to heart, muscles, and nerves
Always consult a qualified doctor for clinical interpretation.
Who Should Get an RFTs Test?
RFTs are highly recommended for:
- People with diabetes
- Patients with high blood pressure
- Individuals with family history of kidney disease
- Long-term medication users
- Adults over 40 years
- Patients with swelling, fatigue, or urinary changes
Symptoms That May Indicate Kidney Problems
- Swelling of feet, ankles, or face
- Persistent fatigue or weakness
- Changes in urination
- Foamy or dark-colored urine
- Nausea or poor appetite
- Uncontrolled blood pressure
Early testing can prevent serious kidney damage.
Why RFTs Are Important for Early Diagnosis
- Detect kidney disease before symptoms appear
- Monitor progression of chronic kidney disease (CKD)
- Prevent complications such as heart disease and electrolyte imbalance
- Guide treatment and lifestyle changes
Frequently Asked Questions
Is fasting required for RFTs?
Fasting is usually recommended for accurate results, but always confirm with the lab.
How often should RFTs be done?
High-risk individuals should test once or twice a year, or as advised by a doctor.
Are RFTs painful?
Only a small needle prick is involved during blood sampling.
Can kidney disease be reversed?
Early-stage kidney disease can often be controlled or slowed with timely diagnosis and treatment.
