Perinatal is not a disease, its a portion of a human lifetime (just ask your mother).
I'm with @Frago on this one. Sounds like more and more development labs have taken a lesson from the astrophysicists: the best "science" starts in the marketing and art department. Whatever these tricorders are, they aren't real until released for production, but they do qualify for feature length documentaries?
Thanks for the querey. Your vital signs are temperature, blood pressure, pulse rate, breathing rate and oxygenation (of blood).
Didn't elaborate on the 13 specific conditions, but diseases fall into categories including cancer, infectious (such as typhoid), parasitic, AIDS, tuberculosis, malaria, cardiovascular diseases, and perinatal.
