As we start the new year 2023, CSL Plasma is adjusting the donor payment week. The new updated week now begins on Saturday and ends on the Friday of the following week. This is effective Dec. 31, 2022.  We are making this change to help donors achieve their first donation at the start of a weekend, as well as to assist with donor service given the volume of CSL Plasma donations we are seeing at our centers. As a reminder, The U.S. Food and Drug Administration (FDA) regulations state that the maximum frequency you can donate plasma is once in a two-day period – and, no more than twice in a seven-day period.
