General Information

Creatinine

Creatinine is a product of muscle metabolism. Its level in urine reflects Kidney filtration capacity. Especially 24-hour urine collection is used For the assessment of kidney function.

In healthy people, creatinine is normally excreted by the kidneys. Because the excretion of creatinine in a particular person is relatively constant, the determination of creatinine in the urine within 24 hours may give us an idea of ​​renal function.

Unlike serum creatinine, urinary creatinine concentration can be additionally used as a parameter to determine other urinary metabolites (eg urinary calcium / urinary creatinine, urinary albumin / urinary creatinine, urinary vanillic acid / urinary creatinine, etc.).

When should we take the test?

When kidney disease is suspected — Nephritis, nephrosis, chronic renal failure

To calculate creatinine clearance — To determine renal filtration rate (GFR)

For treatment monitoring - In case of kidney diseases

Possible interpretation of the results

Urinary creatinine increases in the following diseases:

  • Acromegaly, gigantism
  • diabetes

Urinary creatinine decreases in the following diseases:

  • Chronic renal failure
  • Renal artery stenosis

Exercise, pregnancy, and a diet rich in meat can increase urinary creatinine.

Urinary creatinine should be determined not in isolation but in combination with serum creatinine and creatinine clearance to predict renal function status.

Reference values

The creatinine (24-hour urine) test is used to assess kidney function and especially to calculate creatinine clearance. The results should always be interpreted in conjunction with blood tests and clinical data.
