Study Finds Four-Week Interval Optimal for Circulating Tumor DNA Detection

A recent study identified four weeks as the optimal time to test for circulating tumor DNA (ctDNA). Researchers determined this time frame provided the most effective window for ctDNA detection. The study focused on the timing of ctDNA testing. The research team found that analyzing samples collected four weeks after a specific event offered the highest likelihood of accurately detecting ctDNA. This suggests that a four-week interval may improve the sensitivity of ctDNA-based monitoring strategies.
