The platelet recovery questions refer to initial platelet recovery following the infusion for which the form is being completed. All dates should reflect no platelet transfusions administered for seven consecutive days. Report the date of the first of three consecutive laboratory values ≥ 20 × 109/L obtained on different days, as shown in the Reporting Platelet Recovery example below. Note that platelet recovery may take place well after the recipient has returned to the referring physician for care. It is essential that information and laboratory values be obtained from the referring physician.

Transfusions temporarily increase blood cell counts. When the data is later used for analysis, it is important to be able to distinguish between a recipient whose own body was creating the cells and a recipient who required transfusions to support the counts.

The following example illustrates the procedure to follow for reporting platelet recovery.
