ASA Effect

ASA, also known as acetylsalicylic acid, is a drug commonly taken to help prevent heart attacks and stroke.  However, it has been shown that approximately 25% of individuals who take ASA for this reason actually do not respond to this therapy.

The ASA Effect™ Test is a simple urine test used to identify patients who are resistant to the cardiovascular benefits of daily low-dose ASA consumption.  This test measures the extent of ASA inhibition on thromboxane A2, a powerful proinflammatory molecule implicated in the development of cardiovascular disease.
