How can I tell if this tablet is really valium? Are there benzo reagent kits?

They are from the Phillipines are are unmarked, typical looking colored, sized valium 10mg tablets. They are from a company local to there named "DAZ / Safe Pharma". There is not a marking on the tablet though... they look legit, scored down the middle and all but I want to know if there is anyway to make sure.
