What is a creatinine test?

creatinine test determines the creatinine level in blood or urine. Creatinine is a waste product developed by your daily muscle activities. The kidney filters the creatinine from the blood and excretes it through the urine. The creatinine level shows the working condition of the kidney. The higher creatinine levels in your blood lead to renal or kidney disease. The reason for this is the decreased level of creatinine in the urine. A serum creatinine measures the quantity of creatinine in the blood. The urine creatinine test helps to indicate the total amount of creatinine present in the urine over 24 hours. 

What is the use of the serum creatinine test?

This test examines and diagnoses the function of the kidneys. A serum creatinine test performs along with another kidney test called blood urea nitrogen (BUN). It is also a part of a comprehensive metabolic panel (CMP), a combination of tests that gives information about different organs of your body. A CMP is the most common test for a routine checkup.

When do you need a creatinine test?

The primary goal of this test is to monitor and screen for kidney problems. If you have symptoms of kidney disease, your doctor may recommend this test. Some of the signs include
 
  • Cloudy or bloody urine
  • Fatigue
  • Urine incontinence 
  • Reduction in appetite
  • Painful urine
  • Swelling in the feet or ankles
  • Puffiness near the eyes

You may go for this test if you have symptoms of kidney disease. This include 
 
  • High blood pressure
  • Diabetes type 1 or type 2
  • Kidney disease in family history

How to prepare for a serum creatinine test?

You may need to avoid cooked meat for 24 hours because it may increase creatinine levels. Certain medicines and supplements may have an impact on the creatinine level. You may ask for a prescription from your doctor to reduce the effect of the particular medication that you have used. You can get complete information from your nurse or a doctor for a 24-hour urine sample collection. 

Which sample is required for the test?

A sample of blood or urine may be required for this test. Your lab care provider specifies the sample container.

Creatinine blood test

In this test, you need to provide a blood sample. Your healthcare will take a small amount of blood from your veins. This test is conducted within 5-10 minutes. 

Creatinine urine test

You will collect all your urine produced over 24 hours in a sample container. Follow these steps for a 24-hour creatinine urine test
 
  • Do empty your bladder first in the morning and flush it out. Besides, record the time
  • Put all urine in a specimen for the upcoming 24-hours period.
  • Save that sample of urine in a refrigerator or a cold place
  • You can give the specimen sample to your healthcare provider.

What are the recommended results for this test?

Creatinine levels vary according to a person's size and muscle mass. According to the American Board of Internal Medicine, the value of test results for the creatinine blood test in men is 0.7 to 1.3 mg/dL (61.9 to 114.9 µmol/L). In women, it lies between 0.6 to 1.1 mg/dL (53 to 97.2 µmol/L. Women have lower creatinine levels as compared to men. It is because they frequently have low muscle mass. 

For 24-hour urine, the value ranges from 15 to 25 milligrams per kilogram of body weight (mg/kg). 

The normal range for a creatinine test may vary a little among different labs. Some labs use different measurements or test samples. You can discuss the results of your test with your doctor.

What causes high creatinine in your blood?

When the kidney does not adequately filter the blood, it may lead to a high level of creatinine in the blood. The creatinine level gives you the calculations of the estimated glomerular filtration rate, which helps in accessing the function of the kidneys. High levels of creatinine can occur due to many reasons, such as
 
  • Blocked urinary tract
  • Heart failure
  • Complications of diabetes
  • Kidney infection due to bacteria
  • Autoimmune system disorder
  • Dehydration in the body
  • Muscular problems like rhabdomyolysis 
  • Complications of pregnancy

An abnormality in the creatinine level may not always show a kidney disease. Here are a few more causes that lead to elevated levels of creatinine.
 
  • A diet enriched with red meat
  • Pregnancy
  • Severe exercise
  • Having a greater or less muscle mass, such as obese and malnourished people
  • Certain medications
  • Older people have low creatinine levels due to the reduction in their muscles 
  • Mass

Is there any risk to this test?

You may experience a little pain at the point of your vein where the needle inserts. This pain usually subsides in a short period. For the urine test, there is no risk to your health.

Is there anything else I need to know about a creatinine test?

Your doctor may recommend a creatinine clearance test to obtain accurate information about your kidneys. The creatinine clearance test is a ratio of the creatinine level in the blood to the creatinine level in the urine.
