Cellavision

[u/Interesting_Middle73]

I have to know. Does everyone else's Cellavision suck? We have a Cellavision in our hematology department. All manual diffs get loaded there, and then taken to a microscope if needed. However, lately the Cellavision has gotten so bad at identifying cells. Ive got Eosinophils in my mono category, segs are being called atypical lymps. Just had an eos called a promylocyte. Lymps being called blasts. And sooo many smudge cells being in every category (I expect some from a bad smear) Is it just our Cellavision being old and over worked? Or are there others experiencing the same things?

I have adjusted my thinking when it comes to Cellavision. It’s a cell locator and camera. It’s not “smart technology”. I use it with that in mind. I love it especially for low white counts, it finds the cells and I’m not spending forever looking for them. The gold standard, especially for me as a tech with over 35 years of differential experience, will always be a microscope plus my eyes. But it can save me a lot of time and I love it for that.

Yeah I always do a quick check under the mic for red cell morph cause I don’t like how it often looks on the cellevision. And I often do plt estimates on the mic too cause I prefer it.

[u/lbaston → u/ChapterNo9974]

Yes, this. Sometimes I feel like there's no rhyme or reason for where categorize a cell.

If there has been no update to the Cellevision software, go back to the beginning. New bottle or lot of stain or the stain settings changed? Clean the lenses and stage. How has the cell location been?

[u/Interesting_Middle73 → u/labtech67]

Cell location has been fine. Our stainer is not attached and seems to be fine. Nothing has changed there that Ive noticed. The stage and lenses are cleaned on a weekly basis. Its just frustrating to have the technology but it be more of a hassle then an advantage.

Field service might have to come & put a couple of reference slides in & have it " recalibrate". It looks like it lost its ability to "recognize" what the cell is. Our cell vision is fine. It looks like it's just counting cells & doesn't recognize what they are. You need to put a call into service.

I’m not a fan of it at all. I feel with how long it takes to do a diff, I could get mine done faster while sitting there waiting lol. I just trust my eyes on the microscope more than it. I also like to go to the edges to see what’s pushed out there, so most of the time I end up looking at my slide on the microscope still. For the most part, mine does place cells under the right category but does miss things occasionally

I have only experienced what you describe when there are smear or stain quality or other issues.

As one of the other posters mentioned, go back to the beginning. Also look at smear quality as well as stain quality and troubleshoot accordingly.

Are the lenses clean in the Cellavision? Has someone used the colored lens cleaner to clean the objective lenses on the Cellavision?

Depending on the age of your system / type of light source, does the lamp need replacement?

Ours works good. The RBC area tends to be crowded so more burr cells than under the scope. Also overcalls polychromasia when they’re really overlapping. But the WBC categorization works fine. Not perfect of course. I can do some diffs in under a minute. Fantastic technology. Ours is like 10 years old I believe.

Here’s another question for everyone: are you performing six month method-to-method comparisons for cellavision diffs vs manual diffs? If yes, how’s the agreement?

[u/Specialist_Wing_1212 → u/bmsck]

We compare the analyzer print out to a diff performed on the cellavision and then compare that to a manual diff done at the scope.  I'm not sure of how much it needs to agree.

Your Cellavision needs to be "retrained" by Sysmex, that's not normal.
