Oxidized LDL (oxLDL)
Here’s what it reflects — and what to do about it.
Longetic pulls together every lab and record you’ve had, follows how Oxidized LDL (oxLDL) changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is Oxidized LDL (oxLDL)?
LDL (bad cholesterol) that has been chemically damaged by oxidative stress.
Oxidized LDL is LDL cholesterol that has been altered by oxidative stress, a change that makes it more likely to be taken up into artery walls and to feed plaque buildup. Higher levels have been associated in research with atherosclerosis and cardiovascular risk, and oxLDL is being studied as a marker of unstable plaque. This is an advanced, research-oriented marker rather than a routine blood test.
What to know about Oxidized LDL (oxLDL)
Understanding Oxidized LDL (oxLDL) means knowing what it reflects, what tends to move it, and the signs that suggest it’s worth a closer look — so you can bring the right questions to your next appointment.
