Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

As Beckman Coulter, Inc. (the “Company”) has previously disclosed, the Company is currently conducting a prospective clinical trial to establish the diagnostic performance of its troponin test on its DxI instruments and Access instruments using patient samples from the intended use population. The Company had previously disclosed that it expects to complete such clinical trial in time to submit two separate 510(k) notices to the U.S. Food and Drug Administration (the “FDA”) in the first half of 2011. Based on the current status of the clinical trial, including site and patient enrollment and preliminary myocardial infarction (MI) incidence rates observed, the Company currently expects to submit such two separate 510(k) notices to the FDA for the troponin test during the May/June 2011 time frame, including one 510(k) notice for Access instruments and another for DxI instruments. However, there can be no assurances that such 510(k) notices will be submitted in such time frame or that, upon submission, the updated 510(k) clearances will be received in a timely manner from the FDA, if at all.
