When you use a Home Pregnancy Test (HPT), make sure that
you follow the instructions carefully otherwise you risk
reducing the accuracy. Brands promise an accuracy of 97-99%.
Usual HPTs are able to give a response 6 days after the
fertilization. If a woman has a positive result, she needs
to see her doctor soon. He can confirm a positive HPT result
with a blood test and a pelvic exam, because this is the
only way to know for sure.
