Calling Company About Clinical Studies (interest, year, information, get)

[Solere]

I have done several clinical studies for a company over the past several years and used to get called on a regular basis to see if I'm interested in doing a study. However, I haven't been called in about four months. I do not know why I haven't been called. Would it be polite to call them and ask if they are still doing studies and tell them that I'm still interested in participating when they have them?

You can call them to find out if you're still in the database and to make sure your information is correct, but odds are you aren't being called because they've already used you so much.

Oh ok. Didn't think about that possibility.
