For In Vitro Diagnostic Use.

MicroVue PYD provides a quantitative measure of pyridinium cross-links (Pyd and Dpd) as an indicator of type I collagen resorption, especially bone collagen. Pyd and Dpd are excreted unmetabolized in urine.

MicroVue PYD is intended for use as an indicator of type I collagen resorption, especially bone collagen.
