Ethics of Preanesthesia Mandatory Laboratory Testing

Some practices require mandatory preoperative laboratory testing for select patients presenting for anesthesia and surgery. Such mandatory preanesthesia laboratory testing has significant ethical implications related to informed consent and patient autonomy. Assumptions that a patient provides "presumed consent" by merely presenting for a test are flawed because such consents are often not informed and do not acknowledge patient autonomy. By placing a condition on access to a medical treatment, mandatory preanesthesia testing may not be ethically justifiable. Not all laboratory tests are "ethically equal"; several raise specific questions regarding informed consent, related to their potential to cause significant harm.
