In the grand scheme of things, this is just a curiosity question. Has anyone found that different labs reveal different CEA levels?
I have had 4 levels drawn in three months due to visiting two surgeons in two states, plus a post resection draw and then a draw at my new oncologist.
As follows: 8/26: 0.9, 8/30: 1.8, 10/24: 0.5, 11/22: 1.15
I was hoping to have a baseline moving forward on this journey. Not sure which to ‘use’. Again, rather curious if it’s a lab thing, not a bodily thing. Would inflammation variations make those somewhat subtle differences?
With appreciation,
