We do a type and screen on ALL OB patients coming in for delivery. This way it allows us to deterine antibodies, Rhig evaluation, etc..while the patient is delivering. Saves a lot of time.
If we have a historic type, we do not require a second seperately drawn sample for confirm typing. If the patient does not have a historic type on file, then another type must be preformed on a sample collected at a different time than the TSOB sample.
Usually, we can pull a sample from hemotology seeing as it is also required to draw a CBC before the patient goes home.
