What is a non -invasive testing?
non -invasive testing describes medical testing that does not include physically entering the body or skin. Most tests that are performed during routine physical control are non -invasive. The most common of these tests are blood pressure monitoring, chest tests using a stethoscope and X -rays and other types of scans.
Non -invasive testing is just one type of test physicians who can use the problems that occur in the body. These tests are limited in extent, but will generally be the first choice if they are available because they are easier in patients and include much less risk. Semi -invasive or minimally invasive testing is another type of test that describes blood testing or even colonoscopy where a needle or tube is inserted into the body. Invasive testing usually describes surgery and is the last option for doctors in diagnosing the problem.
X -rays, CT scanning and other types of scans are a great exampley non -invasive testing. This technology uses radio waves that operate with the body and can provide doctors with pictures of the inside of the body. This type of test is qualified as non -invasive because it provides a picture of the inside of the body, does not include any invasive cutting.
Most testing during routine physical examination is considered non -invasive. Visual tests are non -invasive because they only require observation and do not include entering the body. The doctor can shine light inside the ears, nose and neck to get a better picture of any inflammation or other problems that happen inside the body. The stethoscope can also be used to listen to the heart and lungs to make sure they work properly. All these tests are considered non -invasive because they do not disturb the natural boundaries of the body such as skin.
In the field of medical area there is quite a lot of controversy -insistive testVersus more traditional tests. This is especially true for methods of testing heart problems such as arterial blood clots. Many traditional doctors rely on cardiac catheterization, a very invasive type of surgical diagnostic method, to diagnose and then treat blood clots in arteries. These doctors claim that cardiac catheterization is the most accurate way to find blood clots, and because surgery is already underway, clots can be treated then and there.
Advocates of non -invasive heart disease testing claim that these traditional doctors lack the test point. Cardiac catheterization can only detect discrete blockages when present, while CT scan can actually find the basic causes of blockages before they become blockades and potentially infarction. Many heart attacks are caused by prolonged arteries, which are better detected from CT scan than invasive cardiac catheterization.
