Description
Creatinine Test
The Creatinine test measures the level of creatinine, a waste product from normal muscle breakdown, in your blood. It helps evaluate how well your kidneys are filtering and removing waste from the body.
Why It’s Done
| Health Concern | Purpose of Creatinine Test |
|---|---|
| Suspected Kidney Problems | Detect impaired kidney function |
| High Blood Pressure or Diabetes | Monitor kidney damage risk |
| Symptoms like Swelling or Fatigue | Identify early kidney disease |
| Routine Health Checkup | Assess kidney health as part of general panel |
| Monitoring Kidney Disorders | Track progress and effectiveness of treatment |
Result Interpretation
| Creatinine Level | Meaning |
|---|---|
| Normal (Men): 0.74–1.35 mg/dL | Healthy kidney function |
| Normal (Women): 0.59–1.04 mg/dL | Slightly lower due to less muscle mass |
| High Creatinine | Possible kidney dysfunction, dehydration, or muscle disease |
| Low Creatinine | May indicate muscle loss, liver disease, or diet-related issues |
Note: Creatinine levels must be interpreted along with eGFR (Estimated Glomerular Filtration Rate) for a full picture of kidney function.
Symptoms That May Require a Creatinine Test
-
Swelling in legs or around eyes
-
Changes in urination frequency or color
-
Fatigue or shortness of breath
-
Confusion or nausea
-
High blood pressure
Why Choose the Creatinine Test?
-
Simple blood test
-
Detects early signs of chronic kidney disease (CKD)
-
Often part of KFT (Kidney Function Test) panel
-
Helps in medication dosage decisions (e.g., antibiotics, diabetes meds)
 Good to Know
-
Stay hydrated before the test
-
Avoid heavy exercise before testing as it may temporarily raise creatinine
-
Can be paired with BUN (Blood Urea Nitrogen) for deeper insights
Notes
-
Reference ranges can slightly vary based on lab standards, age, and altitude.
-
Always interpret values in consultation with a qualified physician.
