Creatinine, Mass Concentration — Turbidimetric Method
Measures creatinine in a laboratory sample using a turbidimetric method. Creatinine is a muscle waste product filtered by the kidneys and is commonly used to assess kidney function.
["A turbidimetric creatinine result is primarily used to help evaluate kidney function and hydration."]

What is this test?
This test appears to measure the amount of creatinine in a blood or other laboratory sample. Creatinine is a waste product made by muscles and removed from the body mainly by the kidneys.
Why might I need this test?
Creatinine is commonly checked to help assess how well the kidneys filter blood. Results may also be interpreted alongside hydration, muscle mass, diet, and other laboratory findings.
How is the test performed?
For a blood test, a sample is usually collected from a vein. The laboratory adds a special reagent and measures the cloudiness, or turbidity, produced; the amount of creatinine affects that reaction.
How do I prepare for the test?
Routine creatinine testing usually does not require fasting, but follow the instructions for your specific sample. If a urine collection is required, collect it exactly as directed, including any timed or 24-hour collection instructions.
Reference range
Follicular: 1.5-9.0 mIU/mLN/A
For females: inform if menstrual cycle status. For certain tests, timing within menstrual cycle may matter.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A higher creatinine result may occur with reduced kidney filtration, dehydration, or increased muscle mass and may also be affected by certain medicines. A lower result is less common but can occur with low muscle mass, advanced age, or severe liver disease. Results should be interpreted by a clinician using the specimen type, reference interval, and your medical history.
