Use of cystatin C for precise assessment of kidney function and cardiovascular risk

In many situations, it is essential that the physician knows a patient’s kidney function as precisely as possible. The glomerular filtration rate (GFR) is calculated in order to assess kidney function. Various equations and methods exist in that regard, each of which has its advantages and disadvantages. As a paper published today in NDT [1] has now shown, there are clear scientific findings on how to calculate GFR optimally for best possible precision.
