droplet digital PCR

Investigators developed a droplet digital PCR assay targeting driver mutations and found that changes in circulating DNA were correlated with response to radiation.

Investigators using droplet digital PCR methods are following cell-free tumor DNA in the blood, looking for patterns coinciding with immunotherapy treatment outcomes.

Clinicians say they are using blood-based tests for patients who can't be biopsied as a way to get test results sooner, but implementing tests smartly and appropriately remains a challenge.
