FPG: 135 mg/dL What does this result indicate and what, if any, further action is recommended by the ADA? A. Elevated FPG; needs further evaluation by a repeat or alternative test B.

Needs no further evaluation; this is a normal FPG [Ans: - A; The result is elevated. Hyperglycemia is demonstrated by this one FPG. The ADA recommends that the hyperglycemia be demonstrated a second time by repeating the FPG or by using one of the other recommended diagnostic tests.
