This thread is past due. Thank you Janet.

One thing I would request is that when people suggest specialized tests on this forum they include the LabCorp code or the CPT code.

For instance here is the "lipid panel"

LINK

Which includes:
Cholesterol, total;
high-density lipoprotein (HDL) cholesterol;
low-density lipoprotein (LDL) cholesterol (calculation);
triglycerides;
very low-density lipoprotein (VLDL) cholesterol (calculation)

So if you want someone to get their VLDL actually measured instead of calculated then suggest: Lab Corp Test Number: 120295, CPT: 83721

.... I think. I'm not sure..... THAT'S THE PROBLEM!

Asking someone to get any blood test done but without the proper CPT or LabCorp code seems helpful but it's very, very unlikely they are going to figure out how to follow the advice.
