Hi,

This physician is in receipt of recent chemistries . . .

I don't know what 'chemistries' means here. You need to find another word or words.

Best wishes,Clive

Hi barb,

You may be thinking of the fact that the British term for 'a drug store' is 'a chemist's (shop)'.

eg I went into the chemist's to buy some aspirin.

Best wishes, Clive
