Yes, We have a system of cups for future specimens and racks for current date. The cups are labeled Monday thru Friday. After a pre-surgical specimen is tested, we put it in a cup for the day of the week that the surgery is going to take place (so if the 15th is a Wednesday, it goes in the Wed cup). We receive a tentative surgery schedule every day for the following day. We go thru it to see which patients need blood bank testing (based on our OSBOS). We find it in the cup and move it to our "daily" specimen rack. The racks are saved for about 12 days (based on refrigerator space) so we will have the specimen for at least a week after transfusion. The cups are about 4 inches square and the racks hold 24 specimens (each day we fill one or two racks, three is a rarity). It may sound complicated, but it really it isn't. It works for us.
