Problem
A woman sees her OB-GYN physician for her 8 week check up with diagnosis of a normal pregnancy, however, a week later, late at night, she experiences severe abdominal cramping and a vaginal bleeding. She arrives at the emergency room to be examined.
• Based on her symptoms, which laboratory test should be completed?
• If the physician in the emergency room has concerns about the loss of pregnancy, what blood bank test should be completed and why?
