Creatinine
The Creatinine test measures the level of creatinine, a waste product produced by muscle metabolism, in your blood. Clinicians typically order this test to assess kidney function and determine how well the kidneys are filtering waste from the bloodstream. It is commonly used in situations where there are concerns about kidney health, such as in patients with diabetes, hypertension, or those experiencing kidney-related symptoms. Regular monitoring through the Creatinine test can help detect potential kidney issues early, allowing for timely intervention.

Clinical Information
Clinical Significance
Abnormal results from the Creatinine test may indicate potential issues with kidney function. High creatinine levels can suggest impaired kidney function or kidney disease, while low levels might be seen in conditions affecting muscle mass or severe malnutrition. It's crucial to remember that only a healthcare provider can interpret these results accurately and in the context of your overall health and medical history.
Reference Ranges
Reference ranges for creatinine levels can vary based on age, sex, and the specific laboratory methods used. Generally, normal ranges are provided by the lab performing the test, and they consider factors like muscle mass and hydration levels. It's important to interpret these values in the context of individual health; thus, your healthcare provider can help you understand what the results mean for you.
Sample Preparation
Before your Creatinine test, there are generally no special preparations required. However, it’s advisable to inform your healthcare provider about any medications you are taking, as some may affect your results. In most cases, fasting is not necessary, but your doctor may provide specific instructions based on your health condition. If you have any concerns, please discuss them with your healthcare provider prior to the test.
