If you’re genuinely concerned about it, yes, there’s a simple blood test for it. There’s no reason to believe you have it or that it’s harmful however, if you have no symptoms and aren’t a pregnant person. A substantial percentage of the world carries it entirely asymptomatically, so it’s not something you should lose sleep over. Cats take all the heat for it, but there’s lots of ways to catch it in this world.
Incidentally, that whole “it makes you love cats” thing is a myth. There’s some evidence that it can affect the behaviour of rodents in a way that makes them more likely to be caught, but humans are way too complex for an effect such as the internet likes to say it has.
