If someone knows they have a low platelet count, should they get a Covid vaccination?

You should call your doctor and see if you're able to get the vaccine. 

I have the same issue along with other health conditions. I would have to call my doctor and see if I would be ok with getting the vaccine. 

That won't matter. The only medical exclusions for Covid vaccines are severe allergic reaction to its components and autoimmune disorders.

They should check with their doctor.

You need to know how low is low and what vaccine you are taking. 

Call your doctors office for clearance. 

they need to ask their doctor about it
