The data below are derived from Huang N, Foster M, Lentine K et al. Estimated GFR for living kidney donor evaluation. American Journal of Transplantation [epub ahead of print Nov 23 2015].
You can use the numbers above or a different number based on knowledge of your patient’s medical history. For example, if your patient has a strong family history of CKD, you may wish to alter the pretest probability. If so, write the number to be used as pre-test probability in table below.

^{†}Post test probability of mGFR above or below the threshold based on eGFRcr. If you are interested in the opposite of the threshold (eg < 80), then subtract the value given from 100. ^{‡}If you also indicated the eGFRcr-cys, the calculator will use the post-test probability from the eGFRcr as the pre-test probability and use it to compute the post-test probability from eGFRcr-cys. If you are interested in the opposite of the threshold (eg < 80), then subtract the value given from 100. |
