An order can be added to a previous order if there is already an acceptable specimen in the laboratory. Call the laboratory to notify them of the add order request so the patient doesn’t receive an unnecessary venipuncture. Place the order in PowerChart with the comment, “BLOOD IN LAB.” If the laboratory cannot locate an acceptable sample, the Laboratory will cancel the order and notify the floor. Exception: ICU, CCU and NICU will continue to call the laboratory to confirm that a specimen is available prior to entering the order, as their labels print on the patient care unit.
