Vital laboratory package Sport Woman includes 31 values that indicate what changes you can make in your lifestyle habits to improve your fitness and endurance.
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?
You can order the creatinine as a single test from Vital’s online store. Add the desired products to the shopping cart and complete all the tests at once.
No sampling fee for orders over 390 kr! A sampling fee of 200 kr will be added to smaller orders.
Creatinine is included in the following test packages:
Reference values for creatinine
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 | 45 – 90 µmol/L |
Men >18 years | 50 – 100 µmol/L |
The reference levels may vary depending on the laboratory and the test analysis method.
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

A PSA blood test gives you the opportunity to gain insight into your own PSA level. It can provide you with the information to detect and treat prostate cancer at an early stage. We offer this especially to men over 40.
Basophils are white blood cells
Basophils are white blood cells that fight parasitic diseases, prevent unnecessary blood clotting, and mediate allergic reactions.
Hemoglobin (Hb) – Measurement and reference values
When suspecting anemia, it is important to test the hemoglobin. Symptoms of iron deficiency anemia include paleness and fatigue.
Leukocytes – Reference values and general information about white blood cells
White blood cells fight viruses, bacteria, parasites, and other intruders that threaten the health of the body.
Monocytes are white blood cells
White blood cells are an important part of the human immune system. They protect the body from attacks of bacteria, viruses, and parasites. Bone marrow produces five different types of white blood cells, one of which is the monocyte.
Neutrophils
Neutrophils are the most important and common type of white blood cells.
Thrombocytes, blood cell platelet count
Thrombocytes, or platelets, are vital to the functioning of the blood clotting system.
