New Predictive Blood Test: ctDNA
From http://www.theguardian.com. A new ctDNA blood test identifies returning circulating tumor cells before a scan can find cancer recurrence. The old ctDNA used a technique called whole exome sequencing that typically looks for between 16 and 50 mutations. The new test uses whole genome sequencing and searches for 1,800 mutations making it more sensitive. June 2, 2024. This sounds like a real advancement! I wonder when it will be implemented in our treatment.

How is this test different from signatera, this test also detects cancer in the blood before it shows up in scans . It also detects CtDna.

1 ReactionI just looked up the information regarding the Signatera test. I saw two obvious differences. Firstly, they request a tumor sample, besides a blood sample. Secondly, they use the old, whole exhome sequencing which would not be able to find the much larger amount of mutations that the new, whole genome sequencing finds, with the new test.

3 ReactionsContact Natera directly to ask. If you have “commercial insurance” (their words, not mine), then they will attempt to bill your insurance; if insurance denies it, they will appeal. If insurance covers it, you would be responsible for cost up to your deductible / cost-sharing / co-pays.

3 ReactionsWhat exactly is the blood test called? I am on Medicare and I had breast cancer. I would like to have blood test that picks up on microscopic breast cancer you are speaking of. Thank you
My predictive blood test is called Signatera.
