Determining between active and latent TB

From ARUP Labs (May 2009);

QuantiFERON®-TB Gold In-Tube and Mycobacterium tuberculosis Antibody, IgG by ELISA

For use in the diagnosis of latent or active Mycobacterium tuberculosis infection

Test Highlights
• New panel combines the QuantiFERON®-TB Gold in-tube test (QFT- GIT) with the Mtb IgG ELISA.
• Requires only a single patient visit to draw blood sample.
• The nil tube required for the QuantiFERON®-TB Gold in-tube test provides plasma for use in the IgG ELISA, so no extra draw is required.
• Panel increases the ability to differentiate active and latent cases of TB.


Update, whilst InBios TB IgG is covered by CPT code 86609 its status is "For Research Only"
