What do you say about this sample?
by Marcin Balasa
CORRECT ANSWER: This sample was taken to open tube among with other samples. The phlebotomists mixed the caps by mistake after filling the tubes. This is a plasma separating tube (PST). The gele is clearly visible between the serum and cells.
As a conclusion new sample is requested because of potential potassium contamination of K2EDTA tube cap.
