From Jo-Ann Luy:
What percentage of specimens with pseudothrombocytopenia caused by EDTA-dependent platelet satellitosis is resolved by collecting in a sodium citrate tube?

Dear Jo-Ann Luy, I’ve never seen data expressing a percentage, perhaps some of our participants have an answer. Platelet satellitosis in EDTA is relatively common, however, and in my experience it often appears in the sodium citrate tube, although the satellitosis may be less apparent than in the EDTA tube and the platelet count may be a little higher. I recommend whenever you find platelet satellitosis, collect both a sodium citrate and a heparin additive tube, it may be the phenomenon is less apparent in heparin than in the other two. Geo.
