according to ur choice, bof 37 correct answer is d)plasma insulin-like growth factor levels.
but my opinion correct answer is b) glucose tolerance test.
ref:Harrison's page no 2046, 15th edition (diagnosis of acromegaly is confirmed by demonstrating the failure of GH suppression to <1microg/l within 1 to 2h of an oral glucose load (75g).
if i m wrong than what is the different between lab. screening & confirmation diagnosis.
The question is about screening tests, not diagnostic tests. A screening test is used to narrow down the possibilities and weed out the cases in which a positive result is unlikely, before going on to a diagnostic test which is used to confirm the suspected diagnosis.
When answering questions in any examination read the question carefully. Clarify what is being tested .In this question the idea is to find out if the candidate is aware of what tests may be used to screen rather than what tests are used to confirm diagnosis.
