Taking this into account, Dr. Silvestri and colleagues say that the next step from here should be to conduct a “clinical utility study to assess how clinical decision-making and use of invasive procedures are altered with knowledge of the results of [the recently studied] test.”. It can push people out of indeterminate risk and into low-risk — without having to undergo invasive and potential risky procedures.”. “During a biopsy, for example, the lung could collapse and need a tube to expand it,” he explains. Medical information provided on this site is for informational and educational purposes only. For added certainty, however, patients with negative results — and thus with a low likelihood of malign tumors — would still be monitored periodically to make sure that no errors were made.
