DNA screening not always useful for predicting health problems

Letโ€™s say you have a whole lot of money.

Letโ€™s say you have so much money that, even after youโ€™ve purchased a basketball team and a chain of movie theaters, you still have enough cash left over to invest in a maverick approach to your own health care. Should you sink an unspecified sum into ordering every test you can find in the off chance that sooner or later youโ€™re going to detect something valuable?

Mark Cuban says โ€œyes.โ€

In a series of tweets posted at the beginning of this month, the media baron and basketball franchisee admonished his followers that, if they were sufficiently affluent, they should order blood tests for โ€œeverything availableโ€ on a quarterly basis in order to establish a baseline for their own health. In the event of some deviation from the any given personโ€™s aggregate normal values, it might detect some abnormality earlier than it would otherwise be found when it started creating symptoms.

First of all, there is a lot of โ€œeverything availableโ€ to be ordered. While some tests have merit as tools to screen for illness or assess risk of developing diseases later on (examples would include tests of liver function or fasting levels of sugar orย blood lipids), others are only used as part of a more in-depth workup of a problem once itโ€™s detected.
