A pregnancy test is a medical diagnostic procedure used to

determine whether a female has conceived a child. There are two

broad categories of pregnancy tests: at home test and doctor office

tests. The at-home tests are pretty good, up to a 95% accuracy when

used according to the instructions on the box. They are based upon

a reaction with hCG (human choriogonadotropin, a pregnancy-specific

hormone) in the female's urine; this hormone starts to show up

within a few weeks of conception. The doctor's office tests can

either be similar to a home pregnancy test or can be a blood sample

test looking for hCG. In the second trimester of pregnancy, a

doctor can perform an ultrasound examination and identify the fetus

in the uterus.
