Creatinine

CREATININE Test

This Test measures the level of creatinine, a waste product produced by the normal breakdown of muscle tissue. Creatinine is filtered from the blood by the kidneys and excreted in the urine. Since healthy kidneys efficiently remove creatinine from the bloodstream, measuring its level is one of the most reliable ways to evaluate kidney function. Elevated creatinine levels may indicate that the kidneys are not filtering waste effectively.

This test is commonly used to detect, diagnose, and monitor kidney disease, including acute kidney injury (AKI) and chronic kidney disease (CKD). It is often performed as part of a Kidney Function Test (KFT) or comprehensive health check-up and is used to calculate the estimated Glomerular Filtration Rate (eGFR), an important indicator of how well the kidneys are functioning. The Creatinine Test is especially valuable for individuals with diabetes, high blood pressure, heart disease, urinary tract disorders, or a family history of kidney disease, as these conditions increase the risk of kidney damage. It is also used to monitor kidney function before surgery, during hospitalization, or while taking medications that may affect the kidneys.

This Test is Recommended for Individuals:

• Individuals with symptoms of kidney disease, such as swelling, fatigue, or changes in urination.
• People with diabetes or high blood pressure.
• Patients with chronic kidney disease (CKD) or acute kidney injury (AKI).
• Individuals with a family history of kidney disease.
• People taking medications that may affect kidney function.
• Patients undergoing routine health check-ups or pre-operative evaluations.
• Anyone advised by a healthcare provider to assess kidney function.

FAQs

1. What is the Creatinine Test used for?
This Test measures the level of creatinine in the blood to assess kidney function, estimate eGFR, and help detect or monitor kidney disease.

2. Do I need to fast before a Creatinine Test?
Fasting is generally not required for a Creatinine Test. However, your healthcare provider may give specific instructions depending on other tests being performed at the same time.

3. What does a high creatinine level indicate?
A high creatinine level may indicate reduced kidney function due to conditions such as chronic kidney disease, acute kidney injury, dehydration, urinary tract obstruction, or other kidney-related disorders. Your healthcare provider will interpret the results along with eGFR, urine tests, and your medical history.
