What Is an RFT Test?
Your kidneys are the body’s filter. Every day they clean waste out of your blood and pass it into your urine. An RFT measures the waste products left in your blood to see how well that filter is working.
Think of it like checking a water filter. You cannot see inside it, but you can test the water coming out. If waste is building up in your blood, the filter is not doing its job properly.
KFT, Kidney Function Test and RFT: The Same Test
If your slip says KFT, Kidney Function Test, Kidney Profile, or RFTs, that is this test. Pakistani labs use RFT and KFT interchangeably and both mean the same panel. Some slips list the parts separately as Serum Creatinine, Blood Urea, and eGFR.
What Does an RFT Measure?
Panels vary slightly between laboratories. These are the markers usually included.
| Component | What It Shows |
|---|---|
| Serum Creatinine | Waste from muscle activity. Rises when kidneys slow down. The headline number |
| eGFR | Calculated filtering speed. The single best measure of kidney function |
| Blood Urea or BUN | Waste from protein digestion. Also rises with dehydration |
| Uric Acid | Linked to gout and kidney stones |
| Sodium and Potassium | Salt balance, which healthy kidneys keep steady |
The most important line on your report is eGFR. Creatinine on its own can look normal even when your kidneys have lost a large share of their function, because the same creatinine level means very different things in a young man and an older woman. The eGFR adjusts for age and gender and gives the true picture.
RFT Normal Range
Reference values differ slightly between laboratories. These are the ranges commonly used in Pakistan.
| Parameter | Men | Women |
|---|---|---|
| Serum Creatinine | 0.7 to 1.3 mg/dL | 0.6 to 1.1 mg/dL |
| Blood Urea | 15 to 40 mg/dL | 15 to 40 mg/dL |
| Uric Acid | 3.4 to 7.0 mg/dL | 2.4 to 6.0 mg/dL |
| Sodium | 135 to 145 mEq/L | 135 to 145 mEq/L |
| Potassium | 3.5 to 5.1 mEq/L | 3.5 to 5.1 mEq/L |
What Your eGFR Number Means
The eGFR is reported in mL/min. Higher is better. This is the scale doctors use worldwide.
| eGFR | What It Means |
|---|---|
| 90 and above | Normal kidney function |
| 60 to 89 | Mildly reduced. Often normal for older adults |
| 30 to 59 | Moderately reduced. Needs a doctor’s attention |
| 15 to 29 | Severely reduced. Needs specialist care |
| Below 15 | Kidney failure. Urgent specialist care |
A single low reading does not confirm kidney disease. The word chronic means lasting, so doctors usually repeat the test after about three months before making any diagnosis.
What Do High and Low Values Mean?
| Finding | May Suggest |
|---|---|
| High creatinine | Reduced kidney function, dehydration, a very high protein diet, or heavy muscle work |
| Low creatinine | Low muscle mass, pregnancy, or long illness. Rarely a concern |
| High urea with normal creatinine | Often dehydration or a high protein diet rather than kidney damage |
| High urea and high creatinine together | More likely a genuine kidney problem |
| Low eGFR | Reduced filtering. Needs repeating and a doctor’s review |
| High potassium | Can affect heart rhythm. Needs prompt medical attention |
| High uric acid | Gout risk or kidney stones |
Dehydration is the most common innocent reason for a raised reading, which matters in Pakistani summers. Recent illness, heavy exercise, protein supplements, and some painkillers also move these numbers, so let a doctor read the report as a whole.
Why You Need This Test Before Symptoms Appear
Kidneys are quiet. You can lose a large share of your kidney function and still feel completely fine, because the remaining tissue works harder to cover the loss. By the time swelling, exhaustion, or breathlessness appear, the damage is usually well advanced and cannot be reversed.
This is not a small problem here. A community study of 2,873 adults in Karachi found that 12.5 percent of adults aged 40 and over had chronic kidney disease, and most people who have it do not know. The two biggest causes, diabetes and high blood pressure, are both extremely common in Pakistan.
Book an RFT if any of these apply:
- You have diabetes. Yearly kidney checks are standard, because diabetes is the leading cause of kidney failure
- You have high blood pressure
- Kidney disease, dialysis, or kidney failure runs in your family
- You take painkillers regularly, especially diclofenac or ibuprofen, which are hard on kidneys
- You use herbal or unregulated remedies for weight loss or strength
- You have had kidney stones or repeated urine infections
- You notice swelling in the feet or around the eyes, foamy urine, passing urine much more or less than usual, or constant tiredness
- Your doctor has started a medicine that needs kidney monitoring
How to Prepare and What Happens During the Test
Before the test
- Fasting is not usually needed for an RFT alone. If it is bundled with a lipid profile or fasting sugar, follow the fasting rules for those.
- Drink water normally. Being dehydrated can push urea and creatinine up and make the result look worse than it is.
- Avoid heavy exercise and a large meat meal the day before, as both can raise creatinine.
- Tell the lab staff about painkillers, supplements, protein powders, and any herbal remedies you take.
- Do not stop a prescribed medicine to prepare for the test.
During and after the test
- A phlebotomist ties a band around your upper arm and cleans the inside of your elbow.
- A few millilitres of blood are drawn into a small tube.
- The whole process takes under 5 minutes and feels like a quick pinch.
- You can go straight back to normal activity afterwards.
- Mild soreness or a small bruise at the site is normal and fades in a day or two.
Conditions an RFT Can Detect
Chronic kidney disease: a slow loss of filtering over months or years. Caught early, its progress can often be slowed a great deal.
Diabetic kidney disease: the most common cause of kidney failure in Pakistan. This is why yearly kidney checks are part of routine diabetes care.
Acute kidney injury: a sudden drop in function from severe dehydration, infection, or medicines. Often reversible when treated quickly.
Dehydration: common in Pakistani summers and a frequent reason for a temporarily raised urea reading.
Gout and kidney stones: flagged by a raised uric acid level.
If your creatinine comes back high, read our guide on how to lower creatinine naturally, then take the report to a doctor.

آر ایف ٹی ٹیسٹ کی قیمت اور تفصیل
آر ایف ٹی یعنی رینل فنکشن ٹیسٹ گردوں کی کارکردگی جانچنے کا ٹیسٹ ہے۔ پاکستان میں اسے کے ایف ٹی یا کڈنی فنکشن ٹیسٹ بھی کہا جاتا ہے اور دونوں ایک ہی ٹیسٹ ہیں۔ اس میں خون میں کریٹینین، یوریا اور ای جی ایف آر دیکھا جاتا ہے۔ گردے خون سے فضلہ صاف کرتے ہیں، اور جب ان کی کارکردگی کم ہو تو یہ فضلہ خون میں جمع ہونے لگتا ہے۔ سب سے اہم بات یہ ہے کہ گردوں کی خرابی شروع میں کوئی علامت ظاہر نہیں کرتی۔ جب تک پاؤں پر سوجن، تھکاوٹ یا سانس پھولنا شروع ہو، اکثر کافی نقصان ہو چکا ہوتا ہے۔
اس ٹیسٹ کے لیے عام طور پر فاقہ ضروری نہیں، البتہ پانی مناسب مقدار میں پیتے رہیں کیونکہ پانی کی کمی سے رپورٹ خراب آ سکتی ہے۔ لاہور میں مرہم ہیلتھ پلس کے ذریعے آپ یہ ٹیسٹ 1,260 روپے میں، مفت ہوم سیمپل کلیکشن کے ساتھ کروا سکتے ہیں اور رپورٹ اسی دن مل جاتی ہے۔ کراچی میں ہونے والی ایک تحقیق کے مطابق چالیس سال سے زیادہ عمر کے تقریباً ساڑھے بارہ فیصد افراد گردوں کے دائمی مرض میں مبتلا ہیں۔ اگر آپ کو شوگر یا بلڈ پریشر ہے، یا آپ اکثر درد کی گولیاں کھاتے ہیں، تو سال میں ایک بار یہ ٹیسٹ ضرور کروائیں۔ رپورٹ کسی مستند ڈاکٹر کو دکھائیں اور خود سے دوا شروع نہ کریں۔
Frequently Asked Questions
Is RFT the same as KFT?
Yes. RFT means Renal Function Test and KFT means Kidney Function Test. Renal simply means kidney, so both names describe the same panel. Pakistani labs use them interchangeably.
How much does an RFT test cost in Pakistan?
At Marham Health+ the rft test price is PKR 1,260, reduced from PKR 1,800, and home sample collection in Lahore is free. Your report reaches you online the same day.
Do you need to fast for an RFT test?
Not usually. A standard RFT does not require fasting. If your doctor has added a lipid profile or fasting sugar to the same slip, follow the fasting instructions for those. Drink water normally, because dehydration can raise your urea and creatinine.
RFT test kya hota hai?
یہ خون کا ایک ٹیسٹ ہے جو گردوں کی کارکردگی جانچتا ہے۔ اس میں کریٹینین، یوریا اور ای جی ایف آر دیکھا جاتا ہے۔ ڈاکٹر اسے شوگر، بلڈ پریشر اور گردوں کے مرض کی جانچ کے لیے تجویز کرتے ہیں۔
What is a normal creatinine level?
Around 0.7 to 1.3 mg/dL in men and 0.6 to 1.1 mg/dL in women. Read it together with your eGFR, because creatinine alone can look normal even when kidney function has dropped.
Final Thoughts
Kidney damage is silent, common in Pakistan, and largely preventable if you catch it early. An RFT is a simple blood test that gives you the one number that matters most, your eGFR, long before you would feel anything. If you have diabetes or high blood pressure, make it a yearly habit, and take the report to a doctor rather than acting on the numbers alone.
