Hi Zaynab,

Unfortunately I can't give you the normal ranges of these parameters in rats, as they depend on 1. the rat strain being used, 2. the applied laboratory methods, and 3. the accuracy and precision obtained in the laboratory.

Yes, there is a difference between human and rat biochemistry, but the preferred method is to define your own normal range for separate age groups and for male and female rats. And please do participate in a quality control system for clinical biochemistry!

Wishing you much success in your work,

Frederik de Wolff

Thankyou so much for your explanation that's very helpful 

Yes i did a control group and determined the normal range but just for male rats because I was working on them but actually i will do another for female rats 

Thank you for your wishing

Regards
