ACCESS Ostase Part Number: 37300 Used for the quantitative measurement of bone alkaline phosphatase (BAP).

The Access Ostase reagent lot 021281 shows instability resulting in falsely high patient results.

A recall communication was initiated on 6/15/2011 with Beckman forwarding an "Urgent Product Correction" (PCA) letter to all their customers who purchased the Access Immunoassay Systems Ostase Reagent Kits. The letter provides the customers with an explanation of the problem identified and an action to be taken. Customers were instructed to discontinue use of the Access Ostase reagent lot identified on the PCA letter and discard all remaining inventory. As stated in the Instructions for Use for Access Ostase, results should be interpreted in light of the total clinical presentation of the patient. All results generated with reagent lot number 021281 where patient results are higher than expected should be evaluated. The affected lot has been removed from Beckman's inventory, and alternate lots will be provided for all current and future replenishment orders or requests. Customers were instructed to complete and return the enclosed response form within 10 days.
