11.8 - Hazy reports
"Hazy" reports are usually caused by build-up of proteins on the inner wall
of the pipettes. Another cause is growth of micro organisms in the diluter
system. It is extremely important that the system is kept sterile.
Erroneous haziness looks more like haemolytic plasma than 'normal' hazy
plasma. If there is an abnormal number of 'hazy' aspects, check the
dispenser system carefully and clean it if there is any doubt.
Symptoms for a contaminated instrument:
1. If more than
3… 5
out of
20
measurements are reported
HAZY.
2. Poor meniscus may be reported.
3. Incorrect results.
In case of hazy reports:
1. First run an extra
2. Check after a day's run if haziness is decreased. See
3. When there are still many reports, it is recommended to clean the
diluter system. See
