What if you just do these testa every few days? Would this minimize error rate?

- Nifty3929 1y agoProbably not. They are not likely independent. Whatever it is about you that caused the false positive yesterday might likely cause it tomorrow.
- throwup238 1y agoNo, the factors causing the false positives are usually correlated. The most common cause is mutations causing unrelated proteins to mimic an epitope (binding site) of the biomarker protein. Another cause is analytical interference where some other molecule absorbs the wavelength used to measure the assay. Running the test using multiple different labs helps eliminate contamination and handling errors but most false positives are due to genetics and long term environmental factors.
- raffraffraff 1y agoBut if you got one test saying "Detected a fragment of pancreatic cancer DNA" two days later another saying "Didn't see any cancerous DNA fragments" what would the actual effect on the doctor or patient be? Who'll take the risk and say "the first was a false positive"? Also, these tests are a grand a pop if I'm reading it directly (which I may not be)
- para_parolu 1y agoI think it can always be blind process. Only notify when good probability. Plus it can be funnel to other non invasive (possibly) tests. They do cost a lot but that may change with time and scale.
