Annual everything is not evidence-based. Here is how intervals are actually decided, and which popular tests to skip.
The phrase annual check-up is a marketing convention, not a clinical interval. Different things need watching at different frequencies, and some do not need watching at all in a person with no symptoms and no risk factors.
Risk sets the interval, not the calendar
A forty-year-old with normal blood pressure, no family history and no symptoms needs very little. A forty-year-old with a father who had a heart attack at fifty needs a different conversation entirely.
This is why a check that starts with a questionnaire and a history is worth more than one that starts with a panel of tests.
Things genuinely worth checking
Blood pressure, because it is symptomless, common and treatable. Cholesterol, in the context of overall cardiovascular risk rather than as an isolated number. Blood glucose if there is any risk factor at all. Cervical and bowel screening according to the national schedule. Dental examination, because early decay and gum disease are both silent and both cheap to fix early.
Things usually not worth paying for
Whole-body scans in people with no symptoms are the clearest example. They reliably find harmless anomalies, and those findings then generate further scans, biopsies and anxiety, with no demonstrated benefit to survival.
Broad vitamin panels are similar. Unless there is a reason to suspect a specific deficiency, the result changes nothing.
The useful question
Before any test, ask what would change depending on the result. If the answer is nothing, the test is not worth having, however reassuring it sounds. A clinic that cannot answer that question about a test it is selling you is telling you something.
