The creatinine It is a product of the breakdown of an important part of muscle: creatine. Its elimination from the body is through kidneysTherefore, their analyzed values ​​show us how they work. Creatinine values ​​can be calculated in two ways: urinary and thesanguine. When kidney function is abnormal, creatinine increases in the blood and decreases in the urine as it is eliminated through the urine. Creatinine values ​​can vary according to the sex, height and weight of the individual. At OneHowTo.com we explain what are normal creatinine values.

Normal blood creatinine values

In order to obtain the values ​​of creatinine blood sample requires a sample of it, it will be extracted by a nursing professional through the venipuncture. During the reading of the analysis results we will find the creatinine results in the biochemistry section.

Before taking the sample, your doctor may ask you to temporarily stop taking certain medications that can modify the result of the analysis. This is the case of: nephrotoxic drugs, non-steroidal anti-inflammatory drugs, aminoglycosides, heavy drug chemotherapeutics, among others.

To read the results, it must be taken into account that women tend to have lower creatinine levels compared to men since, normally, they have less muscle mass. So normal blood creatinine values ​​are for:

  • women: between 0.6 and 1.1 mg / dl.
  • men: between 0.7 and 1.3 mg / dl

Abnormal blood creatinine values

If the creatinine values ​​are lower the correct ones is usually associated with a muscle problem such as mass loss or a problem of nervous level compromise.

For individuals who obtain from their blood tests high levels creatinine, can be found to be caused by: dehydration, problems with the pregnancy (eclampsia, seizures), urinary tract obstruction or some type of kidney problem (infection, damage)

Normal urine creatinine values

In the case of creatinine in urine, a urine sample pickup for 24 hours in a special jar. The right thing to do is to urinate into the bottle from the time the individual gets up until they lie down. The sample should be kept in a refrigerator until delivery to the laboratory.

It is important to inform the doctor requesting the test if you are taking any drugs such as: antibiotics, cimetidine or cisplatin; since these could interfere with results. Still, do not stop treatment if your doctor does not tell you.

Urine creatinine values ​​(24-hour sample) can vary from 500 to 2000mg / day. Results will depend on age and lean body mass. The normal range according to gender can be interpreted as follows:

  • in women: between 11 and 20 mg per kg of body mass.
  • in men: between 14 and 26 mg per kg of body mass.
