Question

which of the following is used to monitor 3 month average plasma glucose concentrations.
a) glucose tolerance test
b) postprandial glucose
c) serum glucose
d) glycosolated hemoglobin

Explanation:

To determine the correct option, we analyze each choice:

• Option a (glucose tolerance test) assesses how the body processes glucose over a short period (e.g., 2 - 3 hours), not a 3 - month average.
• Option b (postprandial glucose) measures glucose levels after a meal, reflecting short - term (minutes to hours) glucose status.
• Option c (serum glucose) is a snapshot of current glucose levels, not an average over months.
• Option d (glycosolated hemoglobin, like HbA1c) reflects the average plasma glucose concentration over the lifespan of red blood cells (about 3 months), as glucose binds to hemoglobin over time.

Answer:

d) glycosolated hemoglobin
