It is important to understand, however, that people can still have heart disease even with cholesterol levels in the normal range. What makes a screening test valuable is its ability to detect potential problems, while minimizing unclear, ambiguous, or confusing results. However, some screening tests, when used in people not at high risk for disease, or when testing for very rare diseases, can cause more problems than they help. A screening test is done to detect potential health disorders or diseases in people who do not have any symptoms of disease.
Other conditions can cause some of those things, too, like ulcers, Crohn’s disease, and irritable bowel syndrome. Your doctor may do blood tests and take a tiny piece of your intestine to see if you have it. People with high cholesterol measurements from a blood sample have a higher risk for cardiovascular disease , than those with cholesterol in the normal range. Studies have shown that people with high cholesterol can reduce their risk for heart disease by lowering their cholesterol.
In healthy people, doctors take a more selective approach to prevent diseases instead of recommending them with a full body health check-up. There are also some screening tests that your doctor might recommend based on your health history. For example, your physician may recommend a CT lung cancer screening if you are between the ages of 55 and 74 and are a current or former smoker with a history of at least 30 “pack years” of smoking. If you do not meet these guidelines, this screening will not be recommended for you.

The goal is early detection and lifestyle changes or surveillance, to reduce the risk of disease, or to detect it early enough to treat it most effectively. Screening tests are not considered diagnostic, but are used to identify a subset of the population who should have additional testing to determine the presence or absence of disease. If you already have one of the chronic conditions and are on medication, your doctor would be monitoring your condition as a form of management. Please consult your GP on other suitable health screening tests that are necessary for you. Currently, Medisave cannot be used for other health screening such as screening for diabetes or high cholesterol.
