Keywords: Difference Between A ‘Probability’ and an ‘Accuracy’

When it comes to probability and accuracy in paternity tests, what is the difference? Also how can a paternity test or a DNA test be 100% accurate, yet the probability is only 99.99%?

When it comes to the accuracy of DNA tests, this measure actually refers to the quality of the testing procedures used in the lab. This has NOTHING to do with the given results of a paternity test. So, this means that the test itself that is being given to test paternity is 100% accurate, however that 100% accurate test does not guarantee paternity.

There is 100% accuracy that the calculation of the probability of paternity results is 99.99%. This number is based on genetic testing and our reporting procedures.

So while accuracy and probability are closely linked, they don’t always go hand in hand.
