Every procedure performed on a patient requires the patient's informed consent, which the laboratory shall obtain; for routine collection, consent may be taken as given when the patient presents willingly. Special or invasive procedures can call for a fuller explanation and for consent to be recorded. In an emergency where consent cannot be obtained, the laboratory may perform the procedures needed where they serve the patient's best interest.
