Hi @daphne47. I can see you are looking for feedback on osmolality and the testing. Members like @kamama94 and @gingerw may be able to provide some helpful information to get started.

Also, you will see that I have updated the title of this post to allow more members to better connect with you and share their experiences.

Can I ask when your Nephrologist appointment is scheduled for? Also, was that the recommended next step from the physician who requested the other labs?
