Testing Blood Type in Blood Donations

Video Transcript

"Ok so now we are going to follow one of these tubes to the first testing bay and this instrument here is called the Olympus PK7200 and it will test for the AVORH that is your blood group and type, it will also test for CMB virus and will also test for syphilis. So this one instrument will give us four test, it uses the plasma tube because it is going to both cells and plasma for the test. Each one of the donations have a unique bar code so the laboratory at this point doesn't care about the donors name they are using only the bar code. And the instruments are set up so that the instrument will read this bar code and the CPU software will track it all the way through the plates and the testing wells that goes along, very important feature. So this instrument here, we will load the samples up into the rack we will set into the instrument, the instrument then is going to pick up the cells the plasma and all the reagents that are required and deliver it to this plate. So this plate represents channels that will test weather your a group A or group B or a group O or a group AB and then it will test for your RH and then it will test for TP and CnD. So the reaction is a physical reaction and you can actually see it, so the instrument has a camera that will actually look at the reaction in the well, so if its a negative reaction then it will make a cell button and if its a positive reaction the cell don't settle in the bottom of the well. And it measures all that, tell you whether its happy with all the measurements or not and then it pops out the answer. The through put for this instrument per running two hundred to two hundred fifty samples a night it will be about five hours."
