This display is also shown if the “Esc” button is activated in the result status or
any other situation, except during measuring or shutting down.
The Sample ID (see Section 5.4 ) and the Dilution Factor (DF, see Section 5.5 ) is always
displayed in the bottom line when the instrument is in the “ Ready” status or in the
“ Result” status.
5.3 “Result” status
Following a successful analysis, the sperm cell density will be displayed on the display
screen. The instrument is in the
“Result” status.
Figure 22 shows the result from the analysis of an ejaculate, which has a sperm cell
density of 455.0 million sperm cells per ml. It is important to notice that it is the cell
density of the undiluted sample (initial or raw sample), which is presented (see also
Section 5.5 )
The results are always shown with 4-5 digits.
The number of digits does not reflect the precision or the accuracy of the instrument.

5.3.1 Retest flag
In some cases the result is displayed as Display Text Type 9A but with a flashing
“ Retest” message added in line no. 3 ( Figure 23 ). This message is observed when the
image analysis indicates that the image is not a fully normal image. In most cases the
results are still valid. However, it is recommended to retest the sample in order to
obtain a result with a higher degree of reliability.
