eGFR is short for estimated glomerular filtration rate. Your eGFR is a number based on your blood test for creatinine, a waste product in your blood. It tells how well your kidneys are working. The eGFR is a good test, but itâs not right for everyone. For example, this test may not be accurate if you are younger than 18, pregnant, very overweight or very muscular.
The noun VILLAIN has 2 senses: 1. a wicked or evil person; someone who does evil deliberately. 2. the principle bad character in a film or work of fiction. Familiarity information: VILLAIN used as a noun is rare.
c.1300, base or low-born rustic, from Anglo-French and Old French villain, from Medieval Latin villanus farmhand, from Latin villa country house (see villa). The most important phases of the sense development of this word may be summed up as follows: 'inhabitant of a farm; peasant; churl, boor; clown; miser; knave, scoundrel.' Today both Fr. vilain and Eng. villain are used only in a pejorative sense. [Klein] Meaning character in a novel, play, etc. whose evil motives or actions help drive the plot is from 1822.
