How does the test work if pregnancy is twins or multiples?
If you are having identical twins, the test works just like testing a single baby. However if the babies are fraternal twins, typically study results indicate that if the test indicates GIRL than one can assume the babies are all girls. If the test results indicate boy, than one can assume at least one of the babies is a boy. Some studies have indicated that with fraternal twins, and the test indicates BOY in less than the first five minutes of the undisturbed period, it is most likely all the babies are boys.
