Metabolic Service

The Metabolic Service, while based in Auckland at Starship Children's Health, is part of a national service that sees children (and adults) from all around the country.
Children with a metabolic disease have what we call an 'inborn error of metabolism' or IEM - a genetic disease caused by a defect in the function of a cellular protein (e.g. an enzyme or transporter) involved in the metabolism of various chemicals in the body.
Metabolic diseases can be complex to diagnose, can affect multiple organ systems and present at any age in a number of different ways. Many are treatable. In some, early diagnosis even before a baby is born or symptoms begin, can lead to more effective treatment. In others, the aim of diagnosis is to provide information about what to expect for the future, and the risk of disease recurrence in future pregnancies.

Referral Expectations

The Metabolic Service is a national service and sees children from all around the country. In Auckland we see children at Starship Hospital outpatient clinics. We also look after children who are inpatients at Starship and share a ward with Neurology, Neurosurgery and Endocrinology services.

Referrals are made by general practitioners and other specialists. We do accept referrals directly from families if another family member is already known to the service -  e.g. for genetic counselling.

When you come to your clinic appointment, you will always meet one of our consultants, Dr Callum Wilson, Dr Bryony Ryder, Dr John Walter and sometimes one of our Nurse Specialists, Bec Nicol and Denise Rew, and Dietitians, Rhonda Akroyd and Rychelle Winston. We will take a thorough history including pregnancy, birth and early life of the child as well as any current problems. We will often ask for blood and urine tests to help clarify the diagnosis, depending on the reason for the referral.
