Dear colleagues,
A week, or so, ago I posted the question below.
"Does anyone know whether serum gel tubes are suitable/unsuitable for
cryoglobulin estimation? A colleague has recently suggested that cryos might
bind to the gel and cause false negatives.
What do others do?"
Disappointingly I only received 7 replies (thanks to all who did reply).
Of these 7 labs, 3 use serum gel tubes (one of which does not spin the
sample but allows to clot at 37C and then carefully removes the serum) and
the remaining 4 labs use plain serum tubes.
So, the jury seems to be out!
Best wishes
