New tuberculosis test more than skin deep
Date:6/5/2014

at I found surprising was just how much discordance there was between the TST and IGRA tests," says Dr. Schwartz, who was a medical resident at Queen's when he started this research. "Historically, all of those who tested TB-positive by the TST test would have been subjected to 12 months of drug treatments that can have considerable side effects."

IGRA tests can't prove that latent TB infections will progress into active TB until the patient begins to show symptoms. Better tools to predict who will go on to develop active (and potentially infectious) TB are being actively pursued.

"It's such a slow disease progression that it's hard for us to say with certainty who will actually go on to develop TB," says Dr. Wobeser. "I hope that this test will eventually be used in corrections and is able to reduce people who might otherwise be treated unnecessarily for latent TB."
