Product description

B-CrossLaps/serum (B-CTx in serum) REF 11972308 160 100 tests Immunoassay for the in vitro quantitative determination of degradation products of type I collagen in human serum and plasma as an aid in assessing bone resorption. The test may be used as an aid in monitoring antiresorptive therapies (e.g. bisphosphonates, hormone replacement therapy - HRT) in postmenopausal women and individuals diagnosed with osteopenia. The electrochemiluminescence immunoassay ECLIA is intended for use on Elecsys and cobas e immunoassay analyzers.

Reason for recall

Roche Diagnostics internal investigations in R&D have shown that the claims for biotin interference and the sample stability given in the Elecsys ¿-CrossLaps (¿-CL) assay package insert version 5, could not be reproduced. The ¿-CrossLaps test results contribute to the monitoring of antiresorptive therapy. False low or false normal results may lead to delayed diagnosis and treatment of osteoporosi
