Yes, you can collect both an ammonia specimen and a potassium specimen in the same lithium heparin tube. However, it is important to note that the tubes must be labeled correctly so that the laboratory can properly process the specimens. The tube should be labeled with the patient's name, medical record number, date and time of collection, and the type of specimen (ammonia or potassium). It is also important to ensure that the tube is filled to the appropriate level, as indicated on the tube.
