What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Summary

This study collected blood from 43 healthy adults aged 18-60 to serve as a control group for a test that detects circulating tumor cells in cancer patients. Volunteers provided about 20 mL of blood at up to 20 different times. The goal is to make the cancer detection test more accurate by comparing results from healthy people to those with cancer.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help make a blood test for detecting cancer cells more reliable, potentially leading to earlier cancer diagnosis.
What could go wrong
This is a small, completed study with only 43 healthy volunteers. It does not test a treatment, and the results may not fully represent real-world cancer detection scenarios.
