the.com/albuminuria

Protein leaking into urine because your kidneys' coffee filter got a hole in it.

means A medical condition where abnormal amounts of albumin, a blood protein, show up in the urine, usually signaling that the kidneys' filtering units aren't working properly.

from A 19th-century scientific compound built from 'albumin' plus '-uria.' Albumin traces back to Latin albus, 'white' — named for egg white, the purest example of this protein, which turns opaque white when cooked. The suffix '-uria' comes from Greek ouron, 'urine.' Doctors of the era were fond of stitching Latin and Greek together to name whatever they found floating in a patient's sample, and this one stuck once chemists realized that heating suspect urine could make it cloud up just like a poached egg — a clue to failing kidneys.
