Why QuantiFERON®-TB Gold (QFT-Gold) versus tuberculin skin test (TST)?
• QFT-Gold requires one visit versus TST which requires 2 visits (one to have it placed and one to have it read) • QFT-Gold is objective, Yes or No answer versus TST is subjective to open reader bias/interpretation • QFT-Gold is a blood test with no possibility of side effects versus TST where tuberculin is placed in your skin and could cause adverse reactions
