HIV [human immunodeficiency virus) is a virus that affects the body's ability to fight infection. It can lead to AIDS (acquired immunodeficiency syndrome) if left undetected and untreated.

The number of people with HIV in New Zealand is low. However that number is increasing and so all pregnant women are being offered an HIV test as part of their antenatal care. A woman with HIV can pass the virus on to others including her baby during pregnancy, birth or through breastmilk.

The HIV test will be done at the same time as other routine antenatal blood tests )blood group and Rhesus factor, full blood count, hepatitis B, rubella and syphilis). One sample of blood can be used for all the tests.

All of these tests are free to most women.

Informed consent

As with your other antenatal tests it is important that you have enough information to help you decide about having the test.

If you have concerns or want to know more about the HIV test, talk with your GP, midwife specialist. You may also want to discuss it with your partner, family or whãnau.

You have the right to choose not to have any the tests.

Why have an HIV test?

Most pregnant women with HIV do not know have the infection. The test is the only way to tell.

A woman who finds she has HIV is able to ge early treatment and support for herself, her partner, family or whànau and help reduce if risk of passing the virus to her baby.

The majority of pregnant women will be found not to have HIV.

How accurate is the test?

The test is very accurate. However a small number of women may have an unclear result and may need to have a second blood test. In most cases the second test will give a negative result.

How will I get my results?

The health professional who organised your blood tests will give you your results.

If a woman's HIV test is positive, professional advice, help and support will be given to help look after her health, her baby's health and that of her partner, family or whanau. Pregnant women with HIV will be referred for specialist consultant care and treatment.

How effective is the treatment?

Treatment to prevent HIV being passed on to the baby is very effective. Without treatment there is about a 25 percent chance the baby will be born with HIV. With treatment, the chance of the baby being born with HIV is less than 1 percent.

Early treatment and support is important for women who have HIV as it helps them remain well.

What is the treatment?

Pregnant women with HIV will usually be offered a combination of treatment and interventions including:

  • medicines during pregnancy and birth to help women stay healthy for Longer, and to prevent them from passing the virus on to the baby
  • advice about safe delivery methods
  • medicines for the baby which will be offered for a few weeks after birth. Current international evidence suggests that the drug treatment before and after birth causes no harm in babies
  • advice about the safest feeding methods for the baby.

What about confidentiality?

ALL of your antenataL blood test results including HIV will be sent in confidence to your GP or Lead Maternity Carer and to your local District Health Board (DHB].

Even when you choose not to have an HIV test you will be asked if the DHB can be informed of your choice. This information is used to monitor the safety and effectiveness of the programme, regardless of the choice you make.

Your personal details are carefully protected.

Details that could be used to identify you will not be used by the national programme unless you specifically consent to this occurring.

The Antenal HIV Screening Programme is overseen by the National Screening Unit of the Ministry of Health. The programme aims to detect HIV in pregnant women to help reduce the number of babies born with HIV. For further information about this programme visit the National Screening Unit's website:

We have used the services of Family Doctors’ at Smales since 2011. They have provided us with pre-employment screening for our clinical staff as well as on-site Flu vaccinations. Having the vaccinations on site makes it easier for our staff to participate in the annual vaccination programme.

The doctors have also provided us with an in depth occupational health assessment where privacy of the individual was fully respected and the employee made a safe and early return to work.
