Creatinine Test

The Creatinine blood test is used to assess kidney (renal) function. It measures the level of creatinine — a waste product filtered by healthy kidneys — in your blood. Elevated creatinine indicates the kidneys are not filtering efficiently and may point to chronic kidney disease (CKD), acute kidney injury, dehydration, or medication side effects. It is a standard component of the Kidney Function Test (KFT) and Renal Function Test (RFT).

No. Fasting is not required for a standalone Creatinine test. You can eat and drink normally before sample collection. However, avoid very heavy protein meals just before the test, as this can transiently raise creatinine. If your doctor has ordered a full KFT panel or fasting glucose alongside, fasting requirements will be communicated by your Medall team.

The blood draw takes under 5 minutes. If you have booked a home collection, our certified phlebotomist arrives at your scheduled time. Your Creatinine test report is typically ready within 6 hours of sample collection and delivered directly to your email and WhatsApp.

High serum creatinine suggests the kidneys are not filtering waste efficiently. Causes include chronic kidney disease (CKD), acute kidney injury (AKI), dehydration, urinary tract obstruction, or certain medications. Mildly elevated creatinine can also occur after intense exercise or with a high-protein diet. Your physician will interpret results alongside other kidney function markers and your symptoms.

Creatinine is a direct laboratory measurement of the waste product in your blood. eGFR (estimated Glomerular Filtration Rate) is a calculated value derived from your creatinine level, age, sex, and race — it estimates how many millilitres of blood your kidneys clean per minute. While creatinine is a raw marker, eGFR gives a more clinically meaningful picture of kidney function and is used to stage chronic kidney disease.

Yes. Serum Creatinine is a core parameter in the Kidney Function Test (KFT) / Renal Function Test (RFT) panel, which also includes Blood Urea Nitrogen (BUN), Uric Acid, Urea, and Urine Complete Analysis. Together, these tests give your physician a comprehensive assessment of kidney health. All Medall Health Packages from the Pro level upward include a Kidney Function panel.

Yes. Creatinine can be temporarily elevated due to dehydration, intense physical exercise, high dietary protein intake, or certain medications (NSAIDs, creatine supplements). Conversely, individuals with low muscle mass (elderly, malnourished) may have low creatinine even with compromised kidney function. This is why eGFR, BUN, and urine tests are interpreted alongside creatinine for accurate assessment.
