Rhogam eval draw time

Our hospital's policy is that it needs to be drawn within 72 hours postpartum. We would always time it with whatever labs are needed postpartum, or just whenever in the first day.

Thank you. Do you know what reference they used to make that policy?

No, but I can look it up on Monday if you want.

Thank you that would be great!

We draw with labs that are needed or within the first 24 hours if no other labs are needed. We have to give rhogam within 72 hours but we try to do it as soon as we can. I have never heard any reason it needs to be drawn within an hour.

I've never heard the one hour thing either. We just time it with other labs, or do it sometime in the first 24-ish hours.

Our standard practice is to draw the rhogam workup after the blood bank has reported the results of the cord blood and we know whether baby is Rh- or not. Typically with the next blood draw which is the very next morning following delivery.

ACOG's guidelines is to administer rhogam within 72hrs of delivery, but I have not yet found a recommendation for when to draw the workup.

I have, however, heard the folks from blood bank say it should be drawn ASAP after cord blood is reported.

We draw it at the next 0500 draw following delivery.
