It's important to remember that one blood test alone doesn't determine your risk of heart disease and that the most important risk factors for heart disease are smoking, high blood pressure, high cholesterol and diabetes.
A National Diploma is a title that is used to represent a standard of academic or vocational education. The title was first used in the United Kingdom, but has now been adopted by educational systems worldwide.
Alternatively, the document is simply referred to as a degree certificate in these jurisdictions. In Ireland, it is generally called a parchment. The certificate that a Nobel laureate receives is also called a diploma. The term diploma is also used in some historical contexts, to refer to documents signed by a King affirming a grant or tenure of specified land and its conditions (see Anglo-Saxon Charters and Diplomatics).
