Extensive Puhti laboratory package (men) is a great choice when you want to gain more thorough information about the well-being of your body. The Puhti laboratory package will help you check how your body is doing and make better choices for your health. Several tests are included, such as cholesterol, blood glucose, important vitamins, ferritin and testosterone.
Creatinine (Crea)
Creatinine value helps assess kidney function.
Creatinine
- High levels of creatinine in the blood may be a sign of kidney failure.
- Men produce more creatinine than women.
- High levels of creatinine in the blood may cause symptoms such as fatigue and loss of appetite.
What is creatinine?
Creatinine is formed in the muscles in the metabolic reaction of creatine. The body cannot utilize creatinine. Instead, it moves from the muscles into the bloodstream and from there to the kidneys where it is filtered into urine.
Why is creatinine measured?
The creatinine level reflects kidney function thus the creatinine value helps assess kidney function. The creatinine value increases if its excretion in the kidneys is impaired.
Creatinine is measured to determine or monitor kidney function. It is measured when assessing overall health, determining the causes of abnormal symptoms, in the context of kidney-affecting diseases (for example severe infections, diabetes, hypertension, and other cardiovascular diseases), and when starting or adjusting medications that may affect kidneys. A mild increase in creatinine usually does not cause any symptoms or sensations.
How can I get my creatinine tested?
GFR (glomerular filtration rate) test is a more accurate measure of kidney function than creatinine alone.
Check out the Puhti laboratory package, which includes both creatinine and GFR measurements.
The Puhti laboratory package includes 30 different measurements that provide comprehensive information about your overall health. The laboratory package helps you easily see which values are within the reference range, what each value means, and how you can influence them.
Through Puhti, you can also easily book a remote appointment with a doctor as a separate service, during which you can go through all the results.
Reference values for creatinine (fP-Crea/P-Krea)
The amount of creatinine depends on muscle mass. Men produce more creatinine than women. Young, muscular men may have creatinine levels above the reference values even if their kidneys are healthy. The cause of elevated creatinine should always be examined by a doctor.
In addition to gender, age also significantly influences the reference values, as kidney function and the glomerular filtration rate decrease with age. However, the creatinine levels of healthy individuals usually remain stable regardless of age, as our muscle mass also decreases as we get older.
| Women >18 years | under 90 µmol/l |
| Men >18 years | under 100 µmol/l |
The reference levels may vary depending on the laboratory and the test analysis method. Puhti samples are taken and analysed at the laboratories of Mehiläinen.
High creatinine levels
High levels of creatinine in the blood may be a sign of kidney failure.
Concentrations are increased in patients with kidney failure. In severe kidney failure, the creatinine level can increase up to 500–1,000 µmol/L and more, in which case dialysis, also known as renal replacement therapy, may be required.
In addition to kidney failure, creatinine can also be elevated for the following reasons:
- dehydration
- high muscle mass
- heavy physical exertion
- circulatory disorder of the kidneys
- severe general disease, such as a severe infection
High levels of creatinine in the blood may cause symptoms such as fatigue, loss of appetite, changes in urine composition or need to urinate, nausea, and muscle cramps.
Low creatinine levels
Creatinine levels can be low, for example, for the following reasons:
- low muscle mass
- starvation

GFR (glomerular filtration rate) – Measurement and reference values
GFR (Glomerular Filtration Rate) test reflects the kidneys’ ability to cleanse the blood, that is, their ability to remove excess water and waste material from the body.
