Q: My machine gives the error “background abnormal and WBC clog.” It was checked, maintained, calibrated, cleaned all valves and reset software. I am asking for help.
A: It needs to clean WBC Bath using cleaner (hypochlorite). It needs to check volumetric metering board, vacuum value and pressure value.
A: Never calibrate a machine with faults. For the Mindray, you only calibrate when the background is good, and results are consistent but not correct. For the problem you had, it could be the valve connects to the RBC volumetric tube. Check, clean and/or replace. Check the volumetric tube to see if the flow is within count time.
A: One of the problems is also usually the fact that your reagents are in poor condition. You know that after changing the reagents you must adjust the dates. I suggest you keep washing the equipment, analyzing tests with hypochlorite or 70% alcohol.
A: Or your WBC chamber of anode or cathode line is open. If that is the problem you can’t fix it, you just have to replace the chamber. Or if you have a good biomedical technician, he can manage how to get it working.
A: A WBC clog triggers blank abnormal. WBC clog means a longer counting time with two seconds longer than the expected time. The column of fluid is moving inside the metering tube (covered by a metal shield). It may be a clogged ruby/aperture or a faulty valve.
Q: I’m having trouble saving the date in Nemio 30. It does not save the date for the year 2021. Please suggest how I can solve this problem.
A: Hello, this is the procedure I have to change the date and time.
A: You may want to inquire with Toshiba about this. It may be that the Nemio was not expected to last past 2020 and needs a software upgrade or it might be a date bug (try entering 2022 or greater). We no longer have our Nemio, so I can’t test it myself.
A: Can it be BIOS cell problem? That company put cell for 10-20 years life which expire on 31-12-2020 so every time we need to re-enter the date?
A: I doubt very much that it is due to the Bios cell. It would be very difficult to have it die exactly on January 1, 2021 on all units. Plus, if you enter an older date like 2019 or 2020 it keeps it, so that should rule out the battery.
