When ordering blood tests for fasting blood glucose, do I order serum or plasma?  Direct Labs has both.

Thank you,

I doubt it matters much.  Glucose is a very small molecule and is highly likely to distribute fairly evenly across all fractions of blood, so my hunch is that plasma, vs serum, vs whole blood will be very close
