The list of laboratory tests accessed by the link below may be ordered by Doctors of Optometry licensed in New York State to be performed by clinical laboratories certified by the New York State Department of Health. Such tests must be relevant to and inform the diagnosis and treatment of conditions and diseases of the eye that are within the scope of practice of optometry. In cases where such test results indicate a systemic disease or condition that is beyond the scope of practice of optometry, the optometrist shall make a referral to an appropriate physician and facilitate transfer of the test results to the extent feasible.
