EGF

Marker of kidney function

eGFR Cystatin C

eGFR is a marker of kidney function, a low eGFR (estimated glomerular filtration rate) may indicate impaired kidney function.

What is eGFR?

eGFR, which is short for estimated glomerular filtration rate, is good for assessing kidney function. It estimates the glomerular filtration rate (GFR) using formulas based on the plasma concentration of creatinine and/or Cystatin C and their mean value.

When ordering eGFR, the value for cystatin c is used.

What does an elevated or low value of eGFR(CysC) mean?

It is normal to have a high eGFR value. If the value is low, it means that Cystatin C is elevated, which indicates impaired kidney function.

The value of Cystatin C can, however, be affected by other factors such as e.g. an untreated hyperthyroidism and cortisone treatments.

Low values of Cystatin C can occur when the thyroid gland is underfunctioning, which in turn leads to an elevated value of Cystatin C and can then falsely indicate impaired kidney function.

It is important to note that eGFR should not be used as the only method to diagnose kidney disease, and additional tests may be required to confirm the results.

Symptoms of reduced kidney function

The symptoms of chronic kidney failure, or chronic kidney failure, develop slowly. They can only appear when kidney function becomes so impaired that waste products begin to accumulate in the blood, then they can express themselves like this:

  • loss of appetite
  • nausea
  • vomiting
  • fatigue
  • itching
  • impaired muscle power.

Tests containing the marker eGFR Cystatin C

Health checks
Health check - Female

Woman

50 Biomarkers
Blood sample
How does the blood test take place?
Sampling for this test is done via a venous blood sample. The sample is usually taken from a vein in the crook of the elbow and is performed by trained healthcare professionals. How much blood you are allowed to give depends on the number of health markers to be analyzed. The sampling usually takes a few minutes.
Fasting
Fasting

This test requires you to fast before sampling. Fasting means that you are not allowed to eat or drink anything for at least 10 hours before your scheduled time for sampling. However, a glass of water is fine to drink during the fast. Any medications are taken as usual unless your doctor has given other instructions.

  • Health check designed for women.
  • Includes a total of 50 health markers.
  • Gives you information about your overall health.
  • Can identify early signs of health problems.
