(54) Title: METHOD AND APPARATUS TO IDENTIFY FLUIDIC PATH POSITIONS (57) : A method for testing a microfluidic device includes interfacing a microfluidic device to a fluidic parameter testing sys- FIG. 1B tem. The microfluidic device has an internal rotary valve and inter- o nal fluidic channels. Each channel has a port with a predetermined port position that the rotary valve is to align to in order to select 42 any one of a plurality of reagents which flow through the channels. 14 The rotary valve is rotated via the testing system to a plurality of rotary valve position of the rotary valve. A fluidic parameter of the microfluidic device is measured at each rotary valve position. The fluidic parameter is mapped relative to the rotary valve positions. 34 It is determined from the mapping if the rotary valve aligns with each of the predetermined port positions for a flow of the reagents 34 through the channels.
