Time frame
PPV and False Negative Rate can be assessed when plasma and tissue results are available for each patient; average plasma result turnaround time was 4 days, versus average of 20 days for tissue result turnaround time.

What was measured

Concordance between results of plasma genotyping and tumor genotyping, among patients with tissue available for standard genotyping

Analysis population: 35 of the 42 participants with plasma genotyping results also had tumor genotyping results available, so PPV and false negative rate could be assessed in these 35 participants.

Groups in this outcome

Participants With Plasma Genotyping

Participants who enrolled to the study and had plasma genotyping

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
