Trouble finding usable normal ranges for lab tests in clinical trials ? – this may be a solution for you.
Often reference values are missing or vary between local laboratories.
American Board of Internal Medicine has developed a very helpful reference guide for lab values. It can be downloaded here ABIM laboratory-reference-ranges 2021 or you can download the most recent version here from the ABIM website.
Another good alternative for comprehensive reference values is the MSD manual which you can find here
