I just talked with Immucor about this today and told them that if I could find someone else that manufactured a Fetal Bleed Screening test, I would buy it in a second and leave them behind. We, too, are a small facility and would never use 20L before the expiration date. They told me that they had thought about putting the buffered saline in the kits but that it would not work because of the volume needed. They also told me that it was the small hospitals that were having the problem. We have not had a problem with false positives (Hematology does the KB). I think that it is a bunch of "horse hocky". There has to be a better way to fix the "problem". We use saline with a pH of 6.0 - 7.5 from Thermo. The person at Immucor told me that the pH would drop way below that once the cube was opened. He said that by the time it was 3 weeks old the pH would be 5.0. I am not so sure about that. I believe that we will use what we have for as long as we can. Of course, when the new package insert comes out, we will have to figure something else out. I feel that it is a shame that we should have to use our financial resources for something that is not our fault or for something for which we do not have a problem. phouck
