Mantoux
A Mantoux Test is a type of skin test which is typically used to test someone for signs of exposure to Mycobacterium tuberculosis, which is the causative organism for tuberculosis (TB) infection. In this test a small amount of protein from the tuberculosis bacterium is injected into the superficial layer of skin of the forearm. This substance is known as tuberculin or purified protein derivative and is non infectious so it cannot cause tuberculosis, but it will cause the immune system to react and result in an area of raised red skin to appear at the injection site if someone has been exposed to or infected with tuberculosis.
A vaccine against TB (the BCG vaccine-this vaccine is a live vaccine) is available and in Ireland is given to very young children and also to those who may be considered to be at particularly high risk of exposure to TB (for example healthcare workers, laboratory workers etc.).
The Mantoux test is used:
The Mantoux Test requires two visits, firstly to place the test in the top layer of skin in the forearm (an injection is required on the first visit), and then for reading of the result after a period of 48 to 72 hours. It is very important that the Mantoux Test and reading is performed by staff experienced in its use. The BCG vaccine can then be administered if indicated and if the Mantoux Test is negative. The BCG vaccine is typically given into the skin by injection in the top of the arm, and usually leaves a permanent mark. BCG vaccine is usually only given once in a lifetime.
If a Mantoux Test is positive, further investigations may be required including a physical examination, a blood test and chest xray. EHA can help you to determine as part of the risk assessment whether Mantoux tests should be considered and can then deliver a quality Mantoux testing and BCG vaccination program using our online appointment booking facility and dedicated vaccination recording software. We can also manage appointment reminders, any necessary documentation such as consent forms, and can provide a text system to help staff to remember.

The Mantoux test is used:
- to determine that a person is free from TB infection before working in certain jobs (eg, childcare work, healthcare work)
- before BCG is given to adults
- following contact with infectious cases of TB
- as a baseline in certain situations (eg. before travel to areas where exposure to TB may occur, when it is also usually repeated on return)
- as part of immigration requirements to some countries (eg. USA)
