Why do I need a TB test before Humira?
It is possible to have latent TB without developing active TB, but Humira can allow latent TB to become active. It is therefore important to screen for TB before taking Humira and, if you are found to be positive for TB, you should get medical advice on whether it is appropriate to take antibiotics to deal with the TB before starting Humira, whether it is better to avoid Humira altogether or whether to proceed with Humira but be monitored for any development of TB (the decision will depend on your age, general health and whether the TB is active or latent). The most convenient and accurate test is usually the Quantiferon TB gold test or the TSpot TB test. Tests may be available through your GP, local private hospital or TDL (via Dr Gorgy/ARGC etc). Not everyone gets a valid response to these tests though as they depend on having good immune function, so in those cases if a retest is also invalid, you may have to resort to a chest X-ray to check for TB or speak to an immunologist or oth
