NATF is closely monitoring the COVID-19 pandemic and is committed to supporting patients and healthcare providers during this difficult time. We know that the virus poses a significant danger to a key population that we serve: patients with cardiovascular and/or pulmonary diseases. We will continue to update this pages with resources for these patients and for the clinicians who care for them. If there are additional topics you’d like us to cover, please email us at

Please note that NATF does not provide or sell home INR machines. If you’re interested in at-home INR testing, please contact your healthcare provider or health insurance carrier for more information.
