Creatinine, Serum

Serum creatinine is a measurement of the amount of creatinine in the blood. Creatinine is a waste product that results from the normal breakdown of muscle tissue. It is produced at a relatively constant rate and is primarily eliminated from the body by the kidneys.

Why consider this test?

The serum creatinine test is a crucial diagnostic test for assessing kidney function and overall health.

1. Evaluating Kidney Function
2. Diagnosing Kidney Disease
3. Monitoring Kidney Health
4. Preoperative Assessment
5. Evaluating Dehydration

Who should get this test done?

Serum creatinine test is important for a variety of individuals, depending on their health status, risk factors, and specific medical conditions.

1. Individuals with Symptoms of Kidney Problems- Swelling (edema) in the hands, feet, or face, fatigue, shortness of breath, confusion, or changes in urine output (e.g., reduced frequency or dark-colored urine)
2. People with Chronic Conditions- Diabetes, Hypertension (High Blood Pressure)
3. Evaluating Dehydration- Severe Dehydration: In cases of severe dehydration or fluid imbalance, a serum creatinine test can help assess the impact on kidney function and guide appropriate treatment.
4. Individuals with Systemic Conditions- Autoimmune Diseases: Those with systemic conditions like lupus, which can affect the kidneys, might require regular serum creatinine tests as part of their disease management.

More information

Creatinine: A waste product formed from the normal breakdown of muscle tissue. It is produced at a relatively constant rate and is filtered out of the blood by the kidneys.

Serum Creatinine: The concentration of creatinine in the blood. Elevated levels can indicate that the kidneys are not filtering it effectively.

Urine Creatinine: Creatinine is a waste product formed from the normal breakdown of muscle tissue. It is produced at a fairly constant rate and is primarily eliminated from the body through the kidneys.

Estimated Glomerular Filtration Rate (eGFR): eGFR is a calculated value that estimates the rate at which the kidneys filter blood. It provides an indication of kidney function.
