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.
In this test, eGFR is estimated based on the value of Cystatin C, with a low estimate of eGFR, Cystatin C is high, which means impaired kidney function.
This is how it works: The test is a blood test that is carried out at the selected sampling unit.
Sample response: You normally have a response within 6 banking days after taking the sample. The test answer is sent digitally to your e-mail. Together with your test results, you will receive a report in Swedish about your values and the doctor's comment.
Remember: Bring valid identification with you when taking the sample.
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.
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:
The marker eGFR(CysC) is also estimated in Stor Hälsokontroll Man and Stor Hälsokontroll Kvinna.
The sampling is performed by experienced staff at one of our clinics in Stockholm and Gothenburg. Test results and (including any travel certificate) are sent digitally via e-mail.
We will always send you the test result within the same day.
Simple, safe and smooth sampling.
The sample is sent for analysis.
The result is sent digitally.
