All, How would you handle this scenario? (think general lab requirements, not necessarily blood bank requirements) You have a reagent that is made with a powder. The powder expires on Sept. 30, however, when one makes up the solution; the solution itself has an expiration of 6 months. Should the solution stay at 6 months or should it be Sept 30? If you have any CAP/CLIA/NYS standards you could give me to justify your answer that would help too
