There is no automated way of calculating the TP,TN,FP,& FN. You have to determing them manually or atleast the TP.

Usually different results from pregnancy tests come from using the test too early. Taking the test too soon will cause a test to read a false negative.

Always check the kit before using it, including the expiration date and follow directions.
