During a plasma donation, needle was inserted by two phlebs because they couldnt get return.  Once blood was flowing, the machine took one round, returned rbcs with anticoagulant to me, then on the second round, blood would not flow.  They removed the needle and there was a clot.  , and is the clot  dangerous?
