Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Collagenofibrotic glomerulopathy (CG) also called collagen type III glomerulopathy, is a rare kidney disease characterized by large amounts of atypical type III collagen fibrils in the mesangium and subendothelial space of renal glomeruli. Liquid chromatography-tandem mass spectrometry performed on microdissected glomeruli from patients with CG demonstrates a unique proteomic profile. The presence of type III collagen, in the appropriate clinical and pathological context, can be useful to establish a diagnosis of CG.

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
