Normalization issue

I need to analyse saliva samples,
how do you suggest to normalize this kind of biofluid which is not omogeneous? For serum and plasma I usually perform a normalization by volume as indicated in the guidelines but I have some doubt in case of saliva samples. Any suggestions is welcome.
