Factor <scp>VIII</scp> activity of <scp>BAY</scp> 94‐9027 is accurately measured with most commonly used assays: Results from an international laboratory study

Abstract

FVIII activity of BAY 94-9027 was accurately measured with most commonly used one-stage assays used in routine clinical practice. The chromogenic assay was also accurate. It is recommended that clinical laboratories identify and avoid specific inappropriate reagents, such as the APTT-SP and PTT-A, in their one-stage assays for FVIII monitoring.
