I've been on metformin for about 6 or more years but haven't had this problem. If you are seeing a kidney specialist, I would hope his (or her) expertise would determine if it's the medication and if it should be changed. I believe it's best not to eat a lot of meat in the days before taking these tests and to make sure you are not dehydrated. Do you take any blood pressure medication?
Maybe someone can help more with this.
