Observational Study for Cancer Diagnostic Aids

This study is looking at two new blood tests that could help doctors detect cancer. These tests are called a multi-cancer (MC) test and a gastrointestinal-focused (GI) test. You might be able to join if you are 45 years or older and have symptoms, signs, or other findings that suggest you might have cancer. The study wants to see how well these tests work in people who are already showing signs of cancer. The goal is to understand the performance of these tests over 18 months. The study is currently unclear on its recruitment status, but plans to enroll about 1650 people.

Study design
This is an observational study, meaning participants will be observed without receiving an experimental treatment. It plans to enroll about 1650 participants.
What's involved
You would provide a blood sample of up to 40 mL. For those with suspected cancer, clinical outcomes will be tracked after standard diagnostic work-up.
Compensation
Not stated in the trial record.
Follow-up
The primary goal is to assess test performance at 18 months, suggesting a follow-up period of at least that long.
