Critical updates in the 7th edition of the American Society for Apheresis guidelines.

The 7th edition of the American Society for Apheresis (ASFA) guidelines was composed by an international physicians committee, and includes 14 new diseases, and 2 new indications for diseases described in the former guidelines. Several indications have either changed names or were excluded from this edition. The guidelines are developed after taking into account documented evidence, either supporting or negating use of apheresis technology in the treatment of diseases. Based on this evidence, the committee revises, updates and includes or excludes disease entities/indications in the guidelines. This article describes the revisions to the 7th edition of the ASFA guidelines, in a comprehensive manner.
