The Real-Time PCR Internal Control 2B Set consists of reagents intended for use as an unassayed internal extraction and amplification process control in any real-time polymerase chain reaction (PCR) assay. The Internal Control 2B Set can be used to detect systemic variation that may arise during the extraction and amplification process associated with real-time PCR assays. The set is not intended to monitor other real-time PCR processes.

StatusFirst™ CHF (Congestive Heart Failure) NT-proBNP is a rapid test for the in vitro quantitative determination of N-terminal pro-Brain natriuretic peptide (NT-proBNP) in human EDTA plasma. The device is intended for use with the DXpress™ Reader to provide quantitative results as an aid in the diagnosis of CHF.

The StatusFirst™ CHF NT-proBNP test device utilizes biotin coupled anti-NTproBNP antibody/streptavidin solid-phase chromatographic immunoassay technology to quantitatively determine the concentration of NT-proBNP in human EDTA plasma. After a sample has been dispensed into the sample well, the StatusFirst™ CHF NTproBNP test device is placed in the DXpress™ Reader. The DXpress™ Reader displays the NT-proBNP concentration 15 minutes after sample addition. The DXpress™ Reader is programmed to automatically convert the intensity of the test band (as indicated by the "pBNP" line on the test device) into a concentration of NTproBNP by using lot specific calibration factors supplied with each box of 20 StatusFirst™ CHF NT-proBNP test devices. The NT-proBNP concentration in the sample correlates with the intensity of the test band.
