Question

Which level of prolactin definitely suggest prolactinoma?

• A. 300 ng/ml
• B. 150 ng/ml
• C. 200 ng/ml
• D. 100 ng/ml

Answer 1

The Correct Option is C

Prolactinoma is a benign tumor of the pituitary gland that produces excessive amounts of prolactin. Identifying prolactin levels that suggest prolactinoma is crucial for diagnosis. Here's an analysis of prolactin levels:

Prolactin Level (ng/ml)	Interpretation
100 ng/ml	High, but not definitive for prolactinoma
150 ng/ml	High, but not definitive for prolactinoma
200 ng/ml	Indicative of prolactinoma
300 ng/ml	Strongly suggestive of prolactinoma

Prolactin levels above 150 ng/ml can indicate the presence of prolactinoma, though 200 ng/ml is a common threshold used to strongly suggest this condition. Therefore, a prolactin level of 200 ng/ml would definitely suggest the diagnosis of prolactinoma.
