Point noted...
But won't there be potential of auto-adsorption of some sort or some effect on the sample if this step is not done? And when a type and antibody screen is performed, is it not common practice that tubes are spun down, separated and then tested? I guess I assumed it was common practice... when we send out Blood Bank samples to the reference lab, we are asked to separate the samples (plasma/serum from red cells) Please enlighten me...
Thank you
