Important Notice Regarding Quantiferons:

  • To All Quantiferon Clients,

    As many of you know, the Public Health Laboratory was one of the first Texas laboratories to perform Quantiferon testing. We appreciate you choosing to use our laboratory for Quantiferon testing. As part of our commitment to raise awareness about the benefits of IGRA/Quantiferon testing, we strive to keep the test as affordable as possible.

    Due to increasing costs, we have made the decision to adjust our charge for the Quantiferon test. Our new charge will be $75.00. This change will be effective April 01, 2013.

    Thank you for your business. Please call PHLET at 903-877-5071 if you have any questions.
