A full 7 ml lavender top (EDTA) tube is required for blood bank testing. The specimen must be properly labeled to be accepted. Some specimens may need to be kept warm, consult the specific test for transport instructions. The content of each sample label must include the patient's full name and medical record number, the phlebotomist's initials, the date and time the sample was collected and, for non-LLT draws, the initials of a second medical professional who has confirmed that the sample came from the patient whose name is on the label (LLT phlebotomists should write “LLT” for the second set of initials); the computer label must have this same information plus an accession number and the tests ordered.
