## Indications for use
The DuetTM System is an automated scanning microscope and image analysis system. It is intended for in-vitro diagnosis use as an aiding tool to the pathologist in the detection, classification and counting of cells of interests based on particular color, intensity, size, pattern and shape. The DuetTM System is intended to detect the following cell types: 1. Hematopoietic cells stained by Giemsa stain, lmmunohistochemistry 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).
