The Duet™ System is an automated scanning microscope and image analysis system. It is intended for in-vitro diagnostic usc as an aiding tool to the pathologist in the detection, classification and counting of cells of interest based on color, intensity, size, pattern, and shape. The Duet™ System is intended to detect:

1. Hematopoietic cells stained by G-emsa stain, Immunohistochemistry or ISH (with bright field and fluorescent) prepared from cell suspension.

2. Amniotic cells stained by FISH (using direct labeled DNA probes for chromosomes X, Y, 13, 18 and 21>)

3. Cells in urine specimens, stained by FISH (using the Vysis UroVysion™ Bladder Cancer Recurrence Kit for chromosomes 3, 7, 17 and 9p21 locus), from subjects with transitional cell carcinoma of the bladder.

Indications for use as stated in the FDA summary.
