Serum Creatinine (Mass Concentration)

Why This Test Matters

Creatinine levels can indicate how efficiently your kidneys are working. High levels may suggest kidney damage or disease, while low levels might raise concerns about muscle problems or dehydration. Your doctor may order this test to monitor kidney health, especially if you have conditions like diabetes, high blood pressure, or a history of kidney issues.

What to Expect Before the Test

You won’t need special preparation. For blood tests, you’ll typically have a small needle inserted into your arm, and a small amount of blood will be drawn. If you’re on a low-protein diet or have recently exercised heavily, let your healthcare provider know, as these can affect results.

Possible Results and Next Steps

Results are usually reported in milligrams per deciliter (mg/dL). Your doctor will compare your result to your baseline and any known health conditions. If your levels are outside the expected range, further testing or follow-up may be needed to understand the cause and guide treatment.

Common Conditions Affecting Creatinine Levels

Kidney disease, dehydration, muscle disorders, or certain medications can influence creatinine levels. Conditions like heart failure or severe infections may also impact kidney function, leading to elevated creatinine.
