4LgrLife_53 82 Posted September 11, 2014 For surgery, rule of thumb is nothing after midnight. For fasting lab work, the posted signs in the laboratory near to where I live says 12 hours is best for accurate fasting lab work, but it ranges between 8-12 hours of fasting depending on orders of the physician or clinic.
