Hyperprolactinemia is primarily diagnosed by measuring elevated levels of prolactin in the blood, which indicates an abnormal increase of this hormone typically produced by the pituitary gland. In addition to blood tests, imaging tests like MRI are crucial for visualizing the pituitary gland to check for abnormalities such as tumors (prolactinomas). The combined approach of measuring hormone levels and utilizing MRI allows for a comprehensive understanding of both the biochemical and anatomical aspects of the condition, making this option the most thorough and appropriate for diagnosis.

Physical exams can provide some insights but are not definitive for diagnosing hyperprolactinemia. Although imaging tests such as MRI are important, they are often used in conjunction with blood tests rather than as standalone diagnostic tools. A biopsy of the pituitary gland is generally not performed for diagnosing hyperprolactinemia; it is reserved for specific cases where malignancy or other pathological conditions are suspected. Thus, the best diagnostic approach encompasses both elevated prolactin levels and imaging studies.
