Nephrology.
Nephrology consultations at Excelsia with Dr Teresa Chang and Dr Christina Lai across Earlwood, Bangor and Sans Souci. Assessment and management of kidney conditions, from early kidney disease through complex nephrology.
Kidneys and related conditions.
Nephrology is the medical specialty focused on the kidneys and related conditions, including blood pressure control, electrolyte balance, and complications of chronic kidney disease. Nephrologists assess and manage a wide range of conditions, from early-stage kidney impairment through to advanced disease.
Care is coordinated with your GP. Your GP identifies the concern, prepares a referral, and continues general care while the nephrologist advises on the kidney-related question.
Dr Christina Lai is a Nephrologist and General Medicine Physician, which allows her to consider kidney concerns in the context of broader internal medicine.
Common reasons GPs refer.

History, bloods, a plan.
Bring your GP referral, any recent blood tests (particularly kidney function and urine results), imaging, a list of your current medications, and any hospital or previous specialist letters.
- A detailed history including symptoms, family history and lifestyle factors.
- A clinical examination including blood pressure assessment.
- Review of any tests you've already had.
- A management plan that may include further investigation, medication adjustment, dietary recommendations, and follow-up.
Across all three centres.

Common questions.
Do I need to see a GP first?
Yes. A GP referral is required for the Medicare rebate to apply.
What should I bring?
Your GP referral, recent blood and urine test results, any imaging, medication list, and any hospital or previous specialist letters.
Which specialist should I see?
Your GP will match you to the specialist most appropriate for your situation and the centre closest to you.
How urgent is a nephrology referral?
Referrals are triaged based on clinical priority. Early nephrology input is important for chronic kidney disease, and your GP indicates the urgency in the referral letter.
Will I need more tests?
Often. Nephrology relies on blood tests, urine tests and imaging, and additional investigations may be arranged after the initial consultation.
Can Dr Lai see me for general medicine concerns too?
Yes. Dr Lai is a Nephrologist and General Medicine Physician and can provide broader assessment where relevant.
