Really, unless you have a history of a weak D on a patient, or have =/- reactions, there would be no "clue" for you to go straight to fetal cell quantitation and if you have a positive fetal screen you would perform quantitation anyway, right? So who cares about the weak D status?

I am curious as to what literature/standard or research study the 1 hr Plt. expiration and the 6 hr. post thaw is referenced to in your policy. Also, the 30 minute rule has to have supporting studies (I've not encountered anyone who can trace back the original research for this old rule) available. When I performed an inhouse study of 20 red cell units, I found that in many patient units such as Oncology and Geriatric areas, the measured internal temperature was unacceptable ( greater than 10 C ) in as little as 12-15 minutes.
