This article basically talks about a babay who had five drops of blood taken from her 24 hours after she was born. These drops of vblood were taken to help determine whether or not this child has any of the 50 rare hereditary conditions that could be detected and treated. Minnesota doctors say that this saves many lives. However, some argue that this is an invasion of privacy. Doctors want to add other diseases to the newborn screening test. One parent, Ella, thinks that this test should not be optional. So basically, this article is leaning towards the pro side of the argument.
