Is fasting required before a creatinine blood test?

No, fasting is typically not required for a creatinine blood test. You can eat and drink normally before the test unless instructed otherwise by your healthcare provider. However, it’s essential to inform your doctor if you’re on any medications or have recently changed your diet, as these factors can sometimes affect creatinine levels. In some cases, for specialised kidney function tests, specific preparations may be needed, so always follow your doctor's advice.
