Liens transversaux de livre pour 2.4.5 Challenges with blood collection in young children when using IGRAs (but TBST may be used)
IGRA TB infection tests should not be used in children aged 6 months to 2 years, because of insufficient data and the challenges of phlebotomy in this age group. TST or TBST may therefore be preferred. Testing household contacts below 5 years of age is not a prerequisite for providing TPT.
