A paper has just come out in the Archives of Internal Medicine (160:19, 2957-2963) replicating our plasma free metanephrine studies in pheochromocytoma (and a bit more) from a group in Austria.

This group is one of the first to reproduce our plasma free metanephrine assay and their findings provide important independent confirmatory proof of the diagnostic superiority of plasma free metanephrines over other tests.

The title of the article is "Diagnostic Efficacy of Unconjugated Plasma Metanephrines for the Detection of Pheochromocytoma". The paper can be found on the internet at http://archinte.ama-assn.org/issues/v160n19/fig_tab/ioi00068_ft.html

For a complete discussion of this test, please see "Finding Elusive Pheochromocytomas," VHLFF, December 1999.
