Welcome to Medical Tests Home PageWondering why you sneezed so much on your holiday to the green hills despite the perfect weather conditions? Perhaps you are allergic to pollen. To know for sure a simple test for allergies can identify the problem, and then you may take precautions to avoid or even improve the condition. Healthcare has improved dramatically over the past few decades and medical tests have been one of the pillars of this advancement.
A medical test is primarily a diagnostic procedure to identify health problems. You can find out the exact cause of your illness and determine the appropriate treatment depending on the results. Furthermore, a medical test can check the response of the body to the treatment provided. A test can be created to either focus on diagnosing a particular disease or to find out the underlying cause of an illness from the results of a test.
Medical tests are of different kinds - ranging from a simple pH test of urine to a CT scan. Some tests require basic and simple equipments, which can be utilized by a physician in his office, and some tests require a more sophisticated setting with advanced equipments. Data or sample collected at a test can even be sent to laboratories for analysis - e.g. to obtain complete blood count. Samples may also be put under the microscope for analysis.
Medical tests can be classified as invasive, minimally invasive and non-invasive depending on the technique employed. The terms are self-explanatory; invasive refers to an incision or entry of medical apparatus into the body during the medical test. When the entry causes negligible damage to the body at the entry point, it is called as minimally invasive. A non-invasive test is one where there is no physical insertion or entry of apparatus during the test.
In general, medical tests fall into six main categories. Measurement of body functions is done with tests that analyze and study the functioning of the various body organs. For instance, an ECG (electrocardiography) is conducted to measure the electrical activity of the heart. Biopsy includes tests that require a tissue sample to be studied under the microscope to discover any abnormal cells. E.g. tissue from a body part can be studied to find any cancer cells with a biopsy.
Endoscopy refers to tests that are conducted by inserting a viewing tube into the body through an existing or a created cavity. A colonoscopy is a common example of endoscopy; problems can be even corrected during an endoscopy. Analysis of body fluids includes tests that examine urine, blood, cerebrospinal fluid etc. Imaging comprises of all tests like X-rays, ultrasounds and scans where the image of the body may be seen. Analysis of genetic material is done with tests to study cells from the blood, skin etc. Any genetic disorder or disease may be determined by studying the DNA.
Diagnosis of diseases and other problems have been made accurate with the help of medical tests. When your doctor recommends a test for you, get it done, as it will enable you to tackle a problem better, if any is found.
