Creatinine test


  • Results within 24 hours

  • Blood draw included

This test provides a measure of Creatinine in the blood. Creatinine is a waste product produced by muscles that can be used to detect kidney, liver, and muscle disease function based on blood levels of Creatinine. Creatinine levels can be used to determine how efficiently the kidneys are filtering waste product from the body. A venous blood sample will be taken to allow this test to be performed in the clinic and results will be available within 24 hours of sample collection. Click add to cart below to order this test.

What affects creatinine levels?

Creatinine works in relation to the amount of muscle mass a person has, if there is an indication of low creatinine levels, there is usually not a cause for concern. A lack of creatinine can be due to a variety of reasons such as decreased muscle mass, that is found in the elderly, or can periodically be found in advanced liver disease.

Moderate and low exercise is unlikely to impact the levels of creatinine in your blood, frequent exercise and particularly building muscle can marginally increase the creatinine that is created, but not to a level that can harm you.

Due to creatinine being in proportion to muscle mass, women tend to have a lower level of creatinine, although this is dependent on each person.

Why and when should a Creatinine test be taken?

Routine blood tests should include a creatinine test, it can be taken by order of your doctor if kidney problems are suspected, or as a precaution.

Symptoms that can point to kidney, liver, and muscle disease include:

  • Fatigue
  • Swelling
  • Problems urinating
  • High blood pressure
  • Back pain below the ribs

What does the test result indicate?

If high levels of Creatinine are detected, this could indicate issues with the kidneys, and potentially diseases which will affect kidney function, levels of creatinine often increase temporarily after injury to muscles.

Increased creatinine levels can suggest:

  • Kidney stones, prostate disease, and other urinary tract obstructions
  • Reduced flow of blood to the kidney
  • Cells in the kidney dying, which could be due to toxins or drugs
  • Damage/Swelling of the blood vessels in the kidneys.
