Sample Analysis on the CELL-DYN 3200SL
Introduction
This section explains how samples are run on the CELL-DYN 3200SL model in
both Open and Closed Modes. Samples should not be run until daily QC checks
have been performed and the instrument is in the READY state. For convenience,
directions for Daily Start Up and QC are given in each section. Directions for
running samples in the Open Mode are also included in each section. Samples may
be analyzed whenever the
READY
message is displayed in the Status Box on the
RUN
screen.
For Open Mode only, when specimens have not been run for one hour or more, a
background should be run immediately prior to running a patient specimen.
Samples should be well mixed (a mechanical mixer is preferred
3
) before they are
run in the Open Mode on the instrument. For specimens collected in micro-
collection devices, refer to the manufacturer’s instructions for proper mixing and
handling instructions.
The Sample Loader automatically mixes the samples immediately before aspiration.
