CF question

[step1study]

which value should we use to diagnose CF
a) sodium chloride of greater than 60 (in UW this is the value used)
b) sodium chloride of greater than 80 (used in Kaplan qbank)

is it over 60 or over 80???

Ranges I think will always be given on the USMLE, I don't think they require you to know numbers
