Mantoux Testing

Mantoux Test

Dr Gillian Taylor and Dr Damian Marinucci are accredited to perform this test.  Mantoux testing is a screening tool for tuberculosis.  This test is NOT performed on Thursdays or weekends.  Please telephone the clinic to make an appointment for a Mantoux Test.

The Mantoux (pronounced Man-too) skin test is used to see if you have been infected with the germs (bacilli) that cause tuberculosis (TB). It is important to detect TB early so that treatment can be started as soon as possible.

This test is given by an injection between the layers of the skin, usually on the inside of the left forearm using a small sterile needle and syringe.

A positive reaction is measured by the size of the lump (induration) that forms where the injection was put into your ·arm. This lump occurs over the next two to three days.

You may have a positive skin test reaction if you:

  • Have had tuberculosis before and have been cured.
  • Have been exposed to the tuberculosis bacteria or have been immunised for tuberculosis (BCG).
  • Have tuberculosis.

A negative result may actually be incorrect (false negative) if you:

  • Are taking medicine to lower your immunity eg. steroids or chemotherapy drugs.
  • Have a viral illness eg. measles, mumps or rubella.
  • Have been vaccinated with live attenuated viruses within the last month eg measles.
  • Are very sick.

If you have a Mantoux test, you will need to come back in two or three days to have the result of the test checked.   The reaction can be itchy but scratching the test site may cause an infection, so it is best not to touch it.   Bandaids, bandages and ointments can affect the test results, so it is important to keep the skin clear and uncovered (long sleeves and jumpers can be worn).   If you get blisters around the spot where the injection was given, do not break them.

You may do all normal daily activities eg. playing sports, having a shower.
