Appropriate Thyroid Peroxidase Antibody Ordering

The most conclusive evidence for using thyroid peroxidase antibody (TPO) is predictive in nature when evaluating possible subclinical hypothyroidism.  If this test is positive, hypothyroidism occurs at a rate of 4.3% per year versus 2.6% per year when the antibody is negative.  While this scenario does not cover all clinical indications for ordering TPO, there is no definitive evidence that repeat TPO testing provides additional information.1

Based on this information the ordering of TPO within Spectrum Health is being modified.  If the test is ordered more than once on a patient, a screen will appear in EPIC indicating the following: “This test should typically only be resulted once per lifetime.  The duplicate checking indicates that this patient has already had this testing performed.  Please see chart review for results.”   This is not a “hard stop” but providers will need to click “Continue” to proceed with the order.
