Hi all! I am wondering about appropriate ranges for lab work. I had tests done last week, and my protein (Pre albumin) according to Lab Corp was in "normal" range on the scale they showed. But my NUT said that the ranges LabCorp uses are not accurate and that my protein is low. Do different labs have different ranges? If so, what are the correct ranges for DS patients for the various tests that we have run? And, what are the optimal levels that we should have for those tests? I'm afraid that I am not evaluating my levels appropriately. Thank you!
