Stage 4 and dehydration

I have been in stage 4 for abou 1-1/2 years. Recently I developed fluid in my shins. My kidney doc prescribed lasix 20 mg a day. After about a month ago. Recently I become ill and weak. I went to my internists. Bloodwork showed my kidney function down to 17% down from 24% in 4 months. The tests also showed dehydration. So lasix was stopped. I am told that dehydration can skew the results....but I don't know how much. They are repeating tests in 2 weeks. I still feel very poorly 2days without lasix. I was wondering if anyone had experience with this. I am very concerned.

lasix can most definately cause dehydration!  and dehydration can cause a umber of incorrect blood readings also
