Pretty much. A single platelet is basically equivalent to 1 whole blood.
So a double counts as two pints, and a triple counts as three.
The hang up, is that it's not off the donated target of single/double/triple at time of donation but off the final split rate in the lab.post donations the lab pulls a sample off the collection set and runs a cell/plot count to determine concentration of platelets, then they have to sterile split the donation volume into equivalent parts based on the plt concentration in the liquid volume into a standardize medical dose.
So you may give a "double" platelet volume wise up front, however for some reason maybe your plt count was a bit lower so we only get 1 transfuseable dose and then the rest isn't enough to label as a transfuseable product, and has to be discarded.
We run back end cell counts and calibrations to set the machines and get as close as possible and we kpi our split rates, but it happens.
Same with a triple, target a triple but only get a double.
Those back end numbers are what feeds the lab counts for lifetime donations and why it isn't always and 1:1 ratio.
