It’s called GGT. Here’s what one study says about it, in comparison with lipids (aka “cholesterol”). This is in a section discussing what tests life insurance companies use:
Supposedly, GGT is much more predictive than lipids.
This study is for GGT, “Gamma-Glutamyltransferase: A Predictive Biomarker of Cellular Antioxidant Inadequacy and Disease Risk”.
I first heard of GGT from Ivor Cummins. I’ve had GGT tested only once, as I have to pay for it. It’s not part of the normal testing done for a yearly physical.
Anyone else had their GGT taken?
