Erroneous laboratory results

Perhaps some of you have already seen this study on under- and over-testing.

“First we found that the rate of overuse, meaning [medical laboratory] tests that we performed that shouldn’t have been performed, average around 20%. That means out of every 10 tests ordered about two tests on average should not have been ordered.

“Even more surprising was the rate of underuse [of medical laboratory tests]. This is the rate of tests that should have been ordered in a given time but weren’t ordered. That rate was over 40%. So, for every three tests performed, an additional two tests should have been ordered.”

We’ve taken a run at solving suboptimal testing strategies and it’s going very well. We’ll keep you posted on our progress.

This report is just the latest in the Wall Street Journal’s coverage of the Theranos Co. Lab results account for more than 50% of the information in a medical record, thus the impact of these is enormous.
