20 minutes isn't enough time for PCR amplification: I wonder how they do it?
99% accuracy is actually kinda poor. Are those errors false positives or false negatives? And, are the errors random or influenced by the testee in some way (i.e. does the error rate increase, with false negatives, based on diet)?
