I am a 50 yr. old female. my doctors office called and left me a message on my phone saying my kidney function has gotten worse. i looked up my blood?

Unclear question: Not sure what your question is. If you're asking if they can tell how your kidney function is doing by checking your blood, then yes. Also, that msg they left is very general- please call back to clarify. It can be as simple as being dehydrated on the day they took your labs, so they want to recheck. Or one of your meds may be affecting your kidneys. Or your kidneys may be slowing down.
