I have problem of skin itching from 4 to 5 months so I did blood test, in the
liver function profile came normal, in
kidney function profile
Blood urea nitrogen as 5.93mg/dl (normal range is 7 to 18 mg/dl)
creatinine 0.61mg/dl(normal range is 0.7 to 1.4mg/dl).
Hence my blood urea nitrogen and creatinine are less, wether it is a kidney dieases and got skin problem.
IGE test also comes normal.
