What Is The Creatinine Test?

A creatinine blood test determines the concentration of creatinine in the blood. Creatinine is a waste product produced when creatinine, which is found in your muscles, degrades. Creatinine levels in the blood can tell your doctor how well your kidneys work.

When do you need a Serum Creatinine Test?

The following symptoms can be suggestive of health issues related to the kidneys: 

• Fatigue
• Puffy eyes
• Swelling in your feet and/or ankles
• Frequent and painful urination
• Foamy or bloody urine

Your risk of getting kidney disease is higher if you have:

• A family history of kidney disease
• Type 1 or type 2 diabetes
• High blood pressure

Different Creatinine Tests

There are two creatinine tests that help in evaluating kidney function:

1. Serum Creatinine: A blood sample is taken to analyze the creatinine level in one’s bloodstream. Along with personal details such as age and gender, your GFR will be calculated. The higher the creatinine level, the lower the estimated GFR.

2. Creatinine Clearance: For this one, both blood and urine tests are needed to measure the amount of creatinine in the samples for the past 24 hours.

Reasons for High Creatinine Levels

We’ve said that high creatinine levels in your blood is a common indication of kidney damage. However, there are exceptions. Your nephrologists organize them based on three possible causes: pre-renal, renal, and post-renal.
Creatinine may temporarily increase due to certain conditions. These need to be considered when creatinine test results are being analyzed. Otherwise, it may lead to an inaccurate estimate of kidney function.
Here are some factors that may cause high creatinine levels:

Before renal Failure

1. Dehydration

Dehydration leads to kidney disorders as the kidney fails to filter out creatinine effectively.

2. Muscle destruction

Any condition which causes the breakdown of muscle tissue increases creatinine in your blood.

3. Increased protein intake

A high-protein diet leads to high creatinine levels.

4. Hypothyroidism

A dysfunction in your thyroid gland can influence your kidney function and decrease your kidney’s ability to filter out wastes effectively.

5. Creatinine supplements

Creatinine is an amino acid that is frequently added to muscle-building supplements. Intake of these supplements can raise creatinine levels.

During Renal Failure

6. Certain medications

Some medications can raise creatinine because they can damage the kidneys. Always consult with your doctor before intake of such medicines.
 

7. Other diseases

Some infections like Hantavirus or other diseases such as diabetes or high blood pressure can cause kidney damage.

After Renal Failure

8. Kidney Stones

Kidney stones may block the urine flow from your kidneys, and thereby reduce kidney function.
