Creatinine Test


A creatinine test gives us crucial data about the Kidneys. Creatinine is a waste product produced by our muscle metabolism and various other activities (eating meat is one of them!). A healthy kidney filters out creatinine and other waste products from our bloodstream. They are then eliminated through our urine passage.

If your kidneys are not functioning properly an unusual amount of creatinine will be accumulated in your body. A serum creatinine test will measure the amount of creatinine in your bloodstream and determine how well your kidneys filtration process works.


Technical Purpose:

A serum creatinine test measures the amount of creatinine in your bloodstream to see how well your kidneys filtration process works; this indicates whether your kidneys are working properly or not. Creatinine tests may need to be done regularly depending on the type of disease you possess. A diabetes Type 1 or Type 2 patient may need to do it once a year but someone taking medication that heavily affects the kidneys might need to do it more often.


Test Process:

A serum creatinine test is like a common blood test, it does not require any prior preparation. A representative of the diagnostic center will insert a needle in a vein in your arm to take a sample of your blood. This sample will then be sent to the lab for analysis. You can then return to your normal self.

In some cases, the doctor may conduct a urine creatinine test as well. This test will require you to collect your urine for a span of 24 hours in a special container and then submit it for analysis (this is a part of the urine clearance test).


Test Outcome:

Results of the Creatinine blood test are often measured in milligrams per deciliter or micromoles per liter.  The normal range of creatinine present in our bloodstream is 0.84 – 1.21 milligrams per deciliter, this figure varies from person to person. Someone with a higher amount of muscle mass will have more creatinine, this is why men often have more creatinine than women.

A high serum creatinine level shows that your kidneys are not functioning well, this may occur temporally if you’re dehydrated, have low blood pressure, have a high meat intake or take a certain medication.

If the kidney damage is certain It is important to control the factors leading to kidney damage as some damage can be irreversible which will lead to permanent kidney damage.
