The MicroVue Helical Peptide is a test to measure type I collagen helical peptide α1(I) 620-633 in urine, a marker for researching collagen degradation.

Type I collagen is degraded during bone resorption, releasing into circulation peptides of various molecular weights that are further degraded and/or released into urine. A peptide consisting of residues 620-633 derived from the helical region of the α1 chain was isolated from the urine of a patient with Paget's disease.
