- Pre-diabetes (impaired fasting glucose and impaired glucose tolerance)
- Primary hypothyroidism (including subclinical hypothyroidism)
Please note women of child bearing age who are pregnant or considering pregnancy should have thyroxine replaced aiming for a TSH of ≤2.5. Women who are currently pregnant and planning to deliver at RNSH should be referred to the Specialist Obstetric Clinic (Tel: 02 9463 2377, Fax: 02 9926 4061) for ongoing care during their pregnancy. Urgent review of complicated thyroid issues in pregnancy can be reviewed in the Endocrine Clinic and phone advice can be sought by contacting the Endocrine Registrar/Fellow on 02 9926 7111.
- Positive thyroglobulin and thyroid peroxidase antibodies with normal thyroid function
Patients with well-controlled (HbA1c ≤7.0% or 53mmol/mol) type 2 diabetes mellitus who are on diet-control only do not necessarily require specialist review and may be appropriate for our Diabetes Education services or Sydney Diabetes Health Assessment Unit instead (click here).

Cumulative results are always appreciated and the more details that are provided for a patient (including current medications and comorbidities), the better we are able to allocate them to an appropriate and timely clinic.
