WARNING: Unexpected results
An unexpected result may include any result that falls
outside the therapeutic target range, or a result that falls
inside the target range but is not consistent with your current
health status (e.g., you have bleeding or bruising).
What can cause unexpected results:
1. Certain prescription drugs (for example, heparin) and certain
over-the-counter medications (for example, antibiotics) can
affect the action of oral blood thinners and the INR value.
2. Changes in diet, lifestyle, or taking nutritional supplements such
as ginkgo biloba can affect the action of oral blood thinners and
the INR value.
3. Liver diseases, congestive heart failure, thyroid dysfunction,
Lupus, antiphospholipid antibody syndrome (APS) and other
diseases or conditions can affect the action of oral blood
thinners and the INR value.
Be sure your doctor is aware of any of these conditions
before you begin testing, and any time there are changes in
health status or medications after you have begun testing.
What to do when you get an unexpected result:
Follow instructions for re-testing on the Coag-Sense PT/INR
meter. For unexpected results, contact Technical support at
1-866-903-0890. Always follow your doctor's instructions for
adjusting your dose of anticoagulant medication, or any
other corrective actions.
