Clinical Utility

The ST2 Presage® assay kit is an in vitro diagnostic device that quantitatively measures ST2 (growth STimulation expressed gene 2) in serum or plasma by enzyme-linked immunosorbant assay (ELISA) in a microtiter plate format. ST2 Presage® ELISA is indicated to be used in conjunction with clinical evaluation as an aid in assessing the prognosis of patients diagnosed with chronic heart failure.

Procedure

The ST2 Presage® ELISA assay is a quantitative sandwich monoclonal ELISA in a 96-well microtiter plate format for measurement of soluble ST2 in serum, EDTA plasma, or heparin plasma.

Specificity

Specific to human ST2.

Assay Range

ST2 Presage® ELISA measures the analytical range of 3.1 ng/mL to 200.0 ng/mL. The ST2 analysis cutpoint of 35 ng/mL was selected by choosing a Presage® ST2 Assay concentration value above the 90th and below the 95th percentile of the Reference Group.
