Fresenius Medical Care Holdings, Inc.: Citrasate Liquid Acid Concentrate and NaturaLyte Liquid Acid Concentrate are each intended to be used as one component in the preparation of dialysate in a 3-stream proportioning hemodialysis machine according to a physician s prescription. Both concentrates are formulated for use in 45X proportioning systems which proportion a nominal ratio of 1 : 1.72 : 42.28 (acid : bicarbonate : water) to generate dialysate. The dialysate is intended to be pumped through a dialyzer, creating an osmotic gradient across the dialyzer membrane to exchange solutes with blood during hemodialysis.

This caused the product you were delivered to be exposed to freezing or near freezing temperatures for about 3 hours. o o I see you received on . o (if received any PD SOLUTION/SALINE/or CONCENTRATES): Explain that the solutions inside their product are not affected and that we have freeze/thaw studies that prove this. Explain that due to the freezing temperatures, the packaging may become compromised, and they may have seen leaks. For the other products such as Hand Sanitizer and other ancillary products, again, the product could be compromised according to their packaging requirements listed on their packaging. o We are giving you the opportunity to return these products if you choose to do so at this time. o If returning product(s): o Fill out RGA spreadsheet with customer information including how much product they are returning (include lot# and amount returning).
