amym1586 Posted January 8, 2016 Share Posted January 8, 2016 What size tubes do you use? Is the red cell suspension made from whole blood or packed cells? Do you leave the plasma on the red cells in one tube during and storage? Thanks! Kandahlawi 1 Link to comment Share on other sites More sharing options...

Teristella Posted January 8, 2016 Share Posted January 8, 2016 We use 6 ml K3 EDTA tubes and routinely use the packed cells for the suspension. We don't pour off the plasma for storage. amym1586 1 Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted January 8, 2016 Share Posted January 8, 2016 Because of the nature of our work, we usually ask for 2 x 7.5mL tubes (which we occasionally receive, if we are lucky!). We make our own suspensions (as does our grouping automation) from packed cells. The automation does the grouping on a sample with the plasma still in situ, but once we have a group, we remove the plasma. amym1586 1 Link to comment Share on other sites More sharing options...

amym1586 Posted January 8, 2016 Author Share Posted January 8, 2016 Do you go in through the plasma with an automated pipette or a small plastic pipette to collect your red cells ? Link to comment Share on other sites More sharing options...

amym1586 Posted January 8, 2016 Author Share Posted January 8, 2016 We are currently taking whole blood out to make our cell suspension (still doing manual forwards and reverse in tubes) Then spinning down the sample. I want to get them out of that habit and using the packed cells to make our suspensions and hopefully get them to use gel for the forwards and reverses. But we have skinny tubes and big fat pipettes making it impossible to get packed cells without spilling plasma. And I don't know how it'll go if I want special smaller pipettes for bloodbank. Maybe I can order bigger pink tops Link to comment Share on other sites More sharing options...
Teristella Posted January 8, 2016 Share Posted January 8, 2016 We have skinny tubes too. It just takes practice. Drop your plasma for screen and reverse, and crossmatches if you want. Squeeze the pipette and insert into the tube while releasing the bulb so you pull up enough plasma to not spill any. Go nab some of the packed cells, pull the pipette out and squeeze out the cells, but not the plasma. Put the plasma back in the tube immediately and you're good to go! amym1586 1 Link to comment Share on other sites More sharing options...
Eagle Eye Posted January 11, 2016 Share Posted January 11, 2016 What size tubes do you use? 6 ML 13MM Is the red cell suspension made from whole blood or packed cells? PACK CELLS Do you leave the plasma on the red cells in one tube during and storage? SAME TUBE DURING STORAGE amym1586 1 Link to comment Share on other sites More sharing options...
AMcCord Posted January 11, 2016 Share Posted January 11, 2016 (edited) 6 mL Mostly packed cells but not rigid about that ... though we always use whole blood for fetal bleed screens Same tube during storage Cardinal Health has some nice pipettes (CH5214-18) specifically for Blood Bank that are graduated 0.5 mL to 2.0 mL with smaller tips and consistent drop size. Our entire lab uses them for all types of tubes and secondary sample containers for instruments. Teristella's sampling technique works great.

bxcall1 Posted February 3, 2016 Share Posted February 3, 2016 2 tubes, a 3 ml edta and a 7ml edta. Use the small one for cells and spin the big one for the plasma. amym1586 1 Link to comment Share on other sites More sharing options...
TreeMoss Posted February 5, 2016 Share Posted February 5, 2016 We use the pink top K3 EDTA tubes, spin down, and separate off the plasma into a separate tube in case additional crossmatches are ordered on the specimen. We wash our packed cells to make the suspension for testing. amym1586 1 Link to comment Share on other sites More sharing options...
tbostock Posted February 6, 2016 Share Posted February 6, 2016 6 ml, packed, and yes. I am NOT a fan of separating plasma, I think it's a cause of error. AMcCord, Eagle Eye and tricore 3 Link to comment Share on other sites More sharing options...
