Study did not require ethics Approval as it was not considered research.

Early detection and management of pituitary dysfunction reduces the morbidity that ensues as a consequence of missed or delayed diagnosis of this condition, and which may result in life-threatening events and increased mortality.

The investigators study will explore the use of reflex strategies within the laboratory in capturing suspicious pituitary function test results from Primary Care patients and following these up with appropriate reflective testing. Subsequently patients identified from these results to have a possible underlying piuitary dysfunction will have an alert sent to their family physician prompting referral to the Endocrine team for further investigation and management.

Inclusion Criteria:

• Patients from Primary Care found to have one or more abnormal pituitary function test picked up by the laboratory information system in the Clinical Chemistry laboratory.

Exclusion Criteria:

• Patients with known pituitary dysfunction or on medication that may affect pituitary function tests.
