To record a calculated estimation of GFR of a person.

Use to estimate the GFR in stable CKD cases. The equation is as follow: GFR = 186 × (Serum Cr^-1.154) × (age^-0.203) × 1.212 (if patient is black ethnicity) × 0.742 (if female) The serum Cr should be in mg/dL.

Not to be used in acute kidney failure condition.
