CICERO Update: Quantiferon at CHCC!

posted Apr 28, 2014, 6:45 PM by PC/SM Chief Resident
From Erin Goss: 

I wanted to inform you that we now have quantiferon testing available at CHCC after successful lobbying of Rob Beil and the Cicero Program! The lab staff has been trained and the tubes are now available.  


Yearly tuberculosis screening is recommended for all HIV+ patients, however only about 1/3rd of such patients at CHCC have undergone screening in the last 12 months. Help us to improve our screening rates for our HIV+ population by using this tool. 


Please note that the sensitivity of quantiferon and tuberculin skin testing (TST) are similar. False negatives are expected in patients who are anergic to TST, however the specificity of quantiferon is superior. Generally, it is not recommended to test a person with both a TST and quantiferon.

Given the increased cost of quantiferon compared to traditional tuberculin skin testing, our administrative staff have requested that we primarily use quantiferon testing for persons with an increased risk  for LTBI (e.g., recent immigrants, injection-drug users, and residents and employees of prisons and jails).  Testing of persons who are not considered to have an increased probability of infection (those who require tuberculosis screening for forms) should continue to receive traditional testing via PPD. ​
