Referrals per year	500	500
Total QFT-GIT testing costs per year	$0.00	$21755.00	$21755.00
Total LTBI treatment and monitoring costs per year	$137695.00	$104495.00	-$33200.00
Total LTBI-care costs per year	$137695.00	$126250.00	-$11445.00

*Active TB costs attributable to individuals referred to the BCHD TB Control Program who go on to develop active TB disease later in life using a 5 year analytic time horizon; future costs were discounted at 3%. Without discounting, the costs would be $49,005 and $68,135 for the Standard and QFT-GIT strategies, respectively.
