Commercially speaking, in the UK they have to be checked annually, and signed.
brake linings should be checked at 15,000 and 25,000 miles and then every 5,000 miles after that.
How often should you get your cholesterol levels checked? That depends upon your age, your lifestyle choices and whether there is a history of cardiac disease or other health problems in your immediate family. Most health care providers agree that men between the ages of 35 and 65 and women between the ages of 45 and 65 should have regular cholesterol screenings at least once a year. When the results come back, your physician, or the person going over those results with you, may talk about ratios of �good cholesterol� to �bad cholesterol.� What exactly does that mean?

For most people a total cholesterol of 200 and an LDL (low density lipoprotien - "bad cholesterol") of 130 is desirable. We often shoot for an LDL of less than 100 for certain high risk people such as those who have vascular disease and diabetes and we often tolerate LDL's of 160-190 in low risk people.
