Brooklyn, NY –
Shiel Medical Laboratory is the only clinical
laboratory worldwide to offer the Oxidized LDL Triple Marker
Test. It is the only blood test available that measures atherosclerotic
disease activity in the artery wall.
The Shiel Oxidized LDL Triple Marker
Test combines and integrates Three Pathophysiological
Components of the Atherosclerotic Disease Process with Three
Corresponding Independent Biomarkers into One Natural Logarithmic
Equation, Yielding One Numerical Result with One Well-Defined
Coronary Artery Disease Risk Level.
Oxidized LDL – Oxidized
LDL is the atherogenic form of LDL. Oxidized LDL is a plaque-specific
lipoprotein which plays a key role in the atherosclerotic
disease process, particularly in the deposition of cholesterol
in the artery wall plaque. Oxidized LDL is found primarily
in the atherosclerotic plaque and NOT in normal arteries.
Oxidized LDL is directly involved in the initiation and progression
of atherosclerosis: from the early-stage conversion of monocyte/macrophages
into cholesterol-laden foam cells, to the late-stage development
of plaque instability and rupture.
hs-CRP is an independent,
non-specific biomarker of inflammation and tissue injury.
Chronically elevated levels of hs-CRP are associated with
high cardiovascular disease (CVD) risk, whereas persistently
low hs-CRP levels are associated with low CVD risk and even
longevity. Very high (acute) hs-CRP levels (greater than 7.0
mg/L) are associated with infection and acute inflammation,
arthritis, lupus, and other non-cardiovascular diseases. Shiel
Medical Laboratory will not calculate Triple Marker Test results
when the hs-CRP results are greater than 7.0 mg/L, consistent
with acute inflammation.
HDL – High-density-lipoprotein
inhibits the pathophysiological action of Oxidized LDL. In
this regard, HDL should be viewed as an Oxidized LDL antagonist.
HDL is also involved in the removal (reverse transport) of
cholesterol from the artery walls to the blood stream, and
then to the liver where cholesterol is converted to bile acids
and then excreted in the bile. High HDL cholesterol levels
(above 60 mg/dL) are anti-atherogenic and atheroprotective,
and are associated with low risk of coronary artery disease.
In contrast, low HDL cholesterol levels (less than 40 mg/dL)
are associated with a high risk of coronary artery disease.
Key Features of the Oxidized LDL
Triple Marker Test
- Clinically Proven, Innovative Cardiovascular Disease
Risk Assessment Test
- Potential Replacement for All Current Blood Lipid
Tests, including Total Cholesterol and LDL-Cholesterol.
- Reflects Atherosclerotic Disease Activity in the
Artery Wall.
