Diagnosis of DM is suggested by typical symptoms and signs and is
usually best confirmed by which of the following tests?
a. Fasting plasma glucose
b. Measurement of insulin levels
c. Fasting HbA1c test
d. Urine glucose --- correct precise answer ---Answer: A: Fasting
plasma glucose (FPG). DM is indicated by typical symptoms and signs
and confirmed by measurement of plasma glucose. Measurement after
an 8- to 12-h fast or 2 h after ingestion of a concentrated glucose
solution (oral glucose tolerance testing [OGTT]) is best. OGTT is more
sensitive for diagnosing DM and impaired glucose tolerance but is less
convenient and reproducible than FPG. It is therefore rarely used
routinely, except for diagnosing gestational DM and for research
purposes. C: HbA1c measurements reflect glucose levels over the
preceding 3 mo. However, HbA1c values may be falsely high or low,
and tests must be done in a certified clinical laboratory. Point-of-care
HbA1c tests should not be used for diagnosis, but they can be used for
monitoring DM control. D: Urine glucose measurement, once
commonly used, is no longer used for diagnosis or monitoring because
it is neither sensitive nor specific.
