4 min read# Kidney Function Test (KFT) in Hyderabad: Creatinine, eGFR & What Your Results Mean
Your kidneys help filter waste products and excess fluid from your blood. A **Kidney Function Test (KFT)** is a group of laboratory tests that helps assess how well your kidneys are working.
A KFT may include serum creatinine, blood urea and other parameters. The estimated glomerular filtration rate (eGFR) helps doctors understand how efficiently the kidneys filter waste from the blood.
Understanding your KFT results can help identify possible abnormalities and guide further medical evaluation.
## What Is a Kidney Function Test (KFT)?
A Kidney Function Test is a laboratory test panel used to assess kidney health. Depending on the panel, it may include:
- **Serum Creatinine:** Measures a waste product filtered by the kidneys.
- **Blood Urea:** Helps assess waste levels in the blood.
- **eGFR:** Estimates how efficiently the kidneys filter blood.
- **Electrolytes:** Measures substances such as sodium and potassium, if included in the panel.
The exact tests included in a KFT may vary between laboratories.
## Why Is a KFT Recommended?
Doctors may recommend a kidney function test for people with:
- Diabetes or high blood pressure
- A family history of kidney disease
- Suspected kidney problems
- Changes in urination
- Swelling in the feet or ankles
- Existing kidney conditions requiring monitoring
- Certain medicines that require kidney function monitoring
Kidney disease may not cause noticeable symptoms in its early stages. Testing may be recommended for people with relevant risk factors.
## Creatinine and eGFR: What Do They Mean?
**Serum Creatinine**
Creatinine is a waste product produced by normal muscle activity. The kidneys filter it from the blood. Higher-than-expected levels may indicate reduced kidney filtration, although muscle mass, diet, exercise and other factors can also influence the result.
**Estimated Glomerular Filtration Rate (eGFR)**
eGFR estimates how well the kidneys filter blood. It is generally calculated using blood creatinine and other patient factors. Doctors interpret this value alongside medical history and other test results.
### Understanding eGFR Results
| eGFR (mL/min/1.73 m²) | General interpretation |
|---|---|
| 90 or above | Generally within the normal range |
| 60–89 | May indicate mildly reduced filtration |
| 30–59 | Reduced filtration requiring clinical assessment |
| 15–29 | Severely reduced filtration |
| Below 15 | Kidney failure range; prompt medical evaluation is needed |
**Important:** An eGFR result alone does not diagnose chronic kidney disease. Doctors also consider urine albumin, other evidence of kidney damage and whether abnormalities persist over time.
## How to Prepare for a KFT
Preparation depends on the tests included and your doctor's instructions.
- Confirm whether fasting is required.
- Inform your doctor about medicines and supplements you take.
- Follow the laboratory's sample-collection instructions.
- Bring previous reports if you are monitoring kidney function.
Do not stop prescribed medicines unless your doctor advises you to do so.

## Frequently Asked Questions
### 1. What is a Kidney Function Test (KFT)?
A KFT is a group of laboratory tests used to assess kidney function. It often includes creatinine, urea and other parameters, depending on the panel.
### 2. What does high creatinine mean?
High creatinine may indicate reduced kidney filtration, but other factors can affect the result. A doctor should interpret it alongside other findings.
### 3. What is a normal eGFR level?
An eGFR of 90 or above is generally within the normal range. However, other signs of kidney damage and the patient's medical history must also be considered.
### 4. Do I need to fast before a KFT?
Fasting requirements vary depending on the tests ordered. Follow the instructions provided by your doctor or laboratory.
### 5. Where can I get a KFT in Hyderabad?
