Predictive score calculation. Example: The score for an asylum seeker from former Soviet Union, aged 47 without ground transit, no cough, married with previous exposure to TB is equal to: 7+4.7+2+2=15.7. In such case, screening with IGRA is justified. * balkanic asylum seekers demostrate similar LTBI/TB prevalence as native population.
