a false positive is anything that leads to a result that is incorrect for a certain thing. like say i wasn’t your real mother but in the lab i dropped my pubic hair into the test and it came up that i was your real mother… it’s like that.

This is news to me. I always thought it was foolproof. I did a search and it says that if there are 2 possible fathers, and they are biologically related, then a positive can be achieved for both. So there would have to be the mother’s testing, and both possibilities and a comparison. Beside that, I found nothing else.
A false positive is when the test says someone is the father but they are not. The answer is affirmative, or positive, but false.
A false negative is when the test determines that someone is not the father, but in fact they are. In this case the answer is negative, but false.
For paternity testing I assume there would be a higher false positive rate than false negative if the test is done correctly. This is because there is always a small chance that someone shares DNA markers.
False positive result is when the test comes up positive (test said you are the daddy)but the results are wrong
False Negative is when a test comes up negative (you are not the Daddy) but the test is wrong.
In the diagnosis of a disease a false negative result would delay necesary treatmentof a disease because the disease is present but the test did not detect it.
In the diagnosis of a disease a false positive result would cause treatmentof a disease that is really not there.
