Makes me genuinely wonder.. I've donated blood for like 15 times now -- does that make my current blood less saturated with microplastics than if I hadn't?

I was thinking that a kidney dialysis machine might be able to filter out that stuff from your blood. I think the way those work is your blood goes out a tube into the machine and it filters it before sending it back to you. So you'd need filters in there that are fine enough to catch the microplastics.

I don't think any filtering happens in dialysis, unwanted stuff just diffuses to another solution

Correct. If there are actually micro plastics in your blood, the plastic is likely relatively small compared to a blood cell. Otherwise we would be witnessing a lot more issues with stroke/heart attacks. Any kind of filter small enough to filter out something that small would also filter out blood cells.
