Kidney Function Test (KFT): What It Checks and Why It Matters

What is a Kidney Function Test?

A Kidney Function Test, or KFT, measures substances like creatinine, urea, and uric acid in your blood — all of which are normally filtered out by healthy kidneys. Elevated levels can indicate that your kidneys aren't filtering waste as efficiently as they should.

When is a KFT recommended?

• High blood pressure or diabetes (both major risk factors for kidney issues)
• Swelling in the legs, ankles, or around the eyes
• Changes in urination frequency or appearance
• Persistent fatigue or difficulty concentrating
• Family history of kidney disease
• Routine annual health checkups

Why get tested regularly?

Kidney function tends to decline gradually and often without obvious symptoms in the early stages. Regular testing, especially if you have risk factors like diabetes or hypertension, can help catch problems while they're still manageable.
