PRODUCT APPLICATION RESTRICTION
Not for use in in-vivo applications for body fluid constituent
monitoring, including monitoring one or more of the compo-
nents that form, or may be a part of, or contaminate human
blood or other body fluids, such as, but not limited to, car-
boxyhemoglobin, methemoglobin total hemoglobin, oxygen
saturation, oxygen content, fractional arterial oxygen satura-
tion, bilirubin, glucose, drugs, lipids, water, protein, and pH.
