Albumin and Kidney Disease
Organic disease of the kidney does not always give an albuminuria. In even advanced cases of interstitial nephritis (contracted kidney.) no albumin may appear most of the time and only slight traces at the other examinations. In acute nephritis there is a large amount of albumin, part of which comes from the blood that is discharged with the urine. In chronic parenchymatous nephritis (large kidney) there may be a high percentage of albumin. In pyelitis (inflammation of the kidney pelvis) and abscess in or around the kidney there may be albuminuria.
Blood in the urine may be from one or more of various locations and causes which cannot be considered here. Vari¬ous inflammatory processes are the usual causes. The blood may appear as a few scattered cells, as a general red color, or as clots.
