About this test
A Kidney Function Test (KFT/RFT) measures creatinine, blood urea, uric acid and electrolytes, with an estimated GFR, to assess how well your kidneys are filtering. It is used to screen for and monitor chronic kidney disease, especially in people with diabetes or high blood pressure.
Clinical significance
Rising creatinine and urea with a falling eGFR indicate reduced kidney filtration. Electrolyte disturbances (sodium, potassium) can signal kidney or fluid problems and, when severe, can be dangerous. Because early kidney disease is silent, this panel is key for catching damage before symptoms appear in at-risk people.

What does a high creatinine level mean?
A high creatinine usually means the kidneys are filtering less effectively. It can be temporary (dehydration, painkillers, heavy exercise) or a sign of kidney disease, so it is read together with urea and eGFR and often repeated.
Do I need to fast for a kidney function test?
Strict fasting isn't required, but avoid a heavy protein meal the night before and stay normally hydrated for the most accurate creatinine and urea values.
