The flying machine, called Hermes, is packed with sophisticated sensors and built of special carbon fibre.
Officials hope it will help save lives by delivering blood to patients much faster than by road, where emergency vehicles can be held up by traffic jams.
Trials are scheduled to be carried out on Wednesday in southern Poland.
Afterwards the drone is expected to carry out its first live flight from a blood donation centre in the Saska Kępa district of Warsaw to a cardiology clinic in the Anin neighbourhood of the Polish capital.
The date of the flight over Warsaw is not yet known and depends on the result of the trials, public broadcaster Polish Radio’s IAR news agency has reported.
