Bio-Rad Laboratories has released two new cardiac marker controls: Liquichek™ Cardiac Markers Plus Control and Liquichek™ Cardiac Markers Plus Control LT. These comprehensive products can help monitor a wide range of cardiac assessment testing. Both have the same analyte menu, including NT-proBNP, hs-CRP, Troponin I, Troponin T, CK-MB, Myglobin, Homocysteine, total CK, and digitoxin. They have a 3-year shelf life and a 20-day open-vial stability for all analytes. Differences between the products are that the Cardiac Markers Plus Control LT has lower troponin targets than Cardiac Markers Plus Control, and it also has a fourth lower level available. Cardiac Markers Plus Control LT, Level Low helps monitor the lower cardiac marker values associated with risk-stratification testing. These controls are made from human serum and are designed for multiple methods and instruments. Third-party manufacturer controls are not optimized for just one method or instrument, and they provide an unbiased assessment of any testing system. They can help detect changes in assay performance, thus improving the quality of results.
