got this today, its great. Just wondering, is it possible to get a false negative??

False negatives and false positives are always possible. The probability is the issue. Most gastroenterologists don’t do these tests anymore and don’t trust them. Not reliable. Get a colonoscopy.

Can results change After 7 minutes; I had one line now there are two?

I didn't read about this on the instructions but this is generally why there is a specific amount of time mentioned. Leaving a specimen longer can result in false positives - same as with the Covid tests.

Does this detect prostate cancer?

It does not detect prostate cancer. However, it will determine gastrointestinal bleeding/colorectal cancer. -Alfa Scientific

Does this detect blood in the upper gi tract (stomach, esophagus, etc)?

No. The iFOB test is not indicated to detect blood in the upper GI tract (stomach, esophagus, etc.).
