G'day Michael,
"...replaces the tuberculin skin test (PPD, Mantoux Test, Tine Test)."
Very nice. It's great to see the rollout of QFTG into actual usage. It really is looking that many US adopters were waiting for FDA approval for In-Tube and are now jumping on the bandwagon quickly. No doubt we will see many more like this over the coming months. (Hawaii has already jumped)
