Effective Immediately! QuanFERON-TB Gold Plus four-tube assay

The Montana Public Health Laboratory has completed validation of the new 4th generation QuantiFERON®-TB Gold Plus four-tube assay. The 3rd generation QuantiFERON-TB Gold phlebotomy tubes (3 tube assay) are currently being phased out and will no longer be accepted after November 12th.

To help facilitate the change, MTPHL is supplying QFT-Gold Plus 4 tube assay collection kits, collection and ordering instructions, and shipping procedures to all facilities that have requested Quantiferon testing within the past year. Please continue to order tubes as needed.  Other than the addition of a 4th tube, phlebotomy and sample processing procedures remain unchanged.

For more information on specimen collection for the QuantiFERON®-TB Gold Plus four-tube assay, please see the additional attachment, “QuantiFERON Gold Plus collection procedures” document.

If you need more information regarding the new the QuantiFERON® collection kits or testing methods please call Angela Dusko at 406-444-3040.

2018-2019 Influenza Testing Information

It's that time of year again! Please review this year's documents concerning surveillance and diagnostic testing.

Please review the surveillance testing guidelines, developed to allow for geographic monitoring of the circulating strains of influenza and anti-viral resistance trends using existing clinical laboratory testing in addition to Montana Public Health Laboratory testing.

Surveillance Testing Guidelines

Appropriate treatment of patients with respiratory illness depends on accurate and timely diagnosis. Early diagnosis of influenza can reduce the inappropriate use of antibiotics and provide the option of using antiviral therapy. Please review the guidelines for diagnostic influenza testing.

Norovirus Surveillance

Norovirus season is upon us and the Montana Department of Health and Human Services (DPHHS) needs your help this season to improve our outbreak surveillance regarding Norovirus in Montana. Gastroenteritis outbreaks or any outbreaks that occur in congregate settings such as schools, nursing homes and child cares are reportable and provide a glimpse inside infectious diseases in Montana. DPHHS is asking our partners to do their part to improve our understanding of norovirus in Montana. 

Letter to laboratories regarding submission of specimens for Norovirus surveillance and outbreak investigation.
