Measuring oxidized LDL was: Symlin

"The plasma concentrations of glucose and markers of oxidative stress (nitrotyrosine, oxidized LDL [ox-LDL], and total radical-trapping antioxidant parameter [TRAP]) were measured at baseline and during the 4-h postprandial period. "

I've seen a lot of plausible sounding arguments that LDL per se is of
no particular consequence w.r.t atherosclerosis - it's the oxidized LDL
that does the damage.

Are there common lab tests for oxidized LDL, or is this just a test
that research labs run? Are these tests standardized enough, or does
one need a rich description of the "lab normal" outcomes in order to
interpret the result? Is there one widespread test, or are there a
bunch of different methods, with varying accuracies, to choose from?
Is getting a reading after overnight fasting enough, or does one need
multiple draws to get a meaningful measure? If I pressure my endo to
test my oxidized LDL, am I asking for a $20 test or a $600 test?

Anybody?

Thanks
