Creatinine enters the bloodstream as muscle works and leaves through the kidneys. Serum creatinine is used to estimate kidney filtration.

Understanding the test
Also called Kidney Function Marker
Serum creatinine is used to follow kidney function over time and can inform a review of medicines or an illness that may affect filtration.
Comparison with a pre-illness baseline can reveal a recent change in filtration.
A clinician may need an estimate of renal function when prescribing certain medicines.
Before your sample
Fasting is generally unnecessary. Avoid an unusually large cooked meat meal and heavy exercise the day before. Mention creatine supplements and drink normally within any prescribed fluid limits.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

The direction and speed of change are important. An apparently modest result can mean something different in someone with very low muscle mass than in a muscular person.

Bring earlier creatinine and eGFR values. A new change after illness may need different follow-up from a stable personal baseline.

People produce different amounts of creatinine. A muscular build or loss of muscle can affect the result independently of a change in kidney function.
A high creatinine can mean that the kidneys are filtering less efficiently. Fluid loss can temporarily reduce filtration. A large cooked-meat meal, strenuous exercise, creatine supplements and some medicines can also raise the measurement. Tell your clinician about recent changes so they can compare it with your usual result and eGFR.
A low creatinine is usually not concerning. Because creatinine comes from muscle, it is low in people with a small build, low muscle mass, frailty or long-term immobility, and in those who eat very little meat. Pregnancy lowers it too, as kidney filtration increases. Less often it reflects prolonged illness, undernutrition or advanced liver disease.
