The NMR Lipoprotein Fractionation Test uses nuclear magnetic resonance to measure particle size and concentration of LDL, HDL, and VLDL cholesterol. Unlike a standard lipid panel, it provides detailed information on lipoprotein subfractions linked to cardiovascular risk. Doctors use this test to assess heart disease risk, guide cholesterol management, and monitor therapy effectiveness. It offers deeper insight into lipid metabolism and cardiovascular health.

The Cardio IQ™ Triglycerides Test measures triglyceride levels in the blood, an important marker of lipid metabolism and cardiovascular health. Elevated triglycerides are linked to increased risk of heart disease, pancreatitis, and metabolic syndrome. Physicians use this test to assess risk factors, monitor therapy response, and guide lifestyle or treatment decisions, often as part of a broader lipid or heart health evaluation.

The Cardiolipin IgG IgA IgM Antibodies Test detects autoantibodies linked to antiphospholipid syndrome (APS), a disorder that increases the risk of blood clots, stroke, and pregnancy complications. Measuring IgG, IgA, and IgM helps identify abnormal immune responses. Doctors use this test to evaluate patients with unexplained clotting, recurrent miscarriages, or autoimmune disease, guiding diagnosis and treatment of APS and related conditions.

The Cardiolipin IgA Antibody Test detects IgA antibodies to cardiolipin, helping assess clotting disorders, autoimmune disease, and vascular complications. High levels are often linked to antiphospholipid syndrome, pregnancy loss, or thrombotic conditions. This test provides insight into immune activity, coagulation balance, and systemic disorders influenced by antibody-mediated vascular dysfunction.

The Cardiolipin IgG Antibody Test detects IgG antibodies to cardiolipin, often associated with autoimmune disease. Abnormal results may indicate antiphospholipid syndrome, blood clotting disorders, or pregnancy complications. This test provides insight into thrombotic risk, vascular health, systemic inflammation, and immune activity linked to autoimmune conditions and antibody-mediated disease.

The Cardiolipin IgM Antibody Test measures IgM antibodies linked to antiphospholipid syndrome and autoimmune disorders. It helps evaluate unexplained blood clots, recurrent miscarriages, or abnormal clotting events. By detecting immune system activity against phospholipids, this test supports the assessment of vascular health, autoimmune activity, and risks related to thrombosis or systemic lupus erythematosus.

The Catecholamines Fractionated 24-Hour Urine Test with Creatinine measures epinephrine, norepinephrine, and dopamine excretion, normalized to creatinine, to assess adrenal gland and sympathetic nervous system function. Elevated levels may indicate pheochromocytoma, paraganglioma, or other neuroendocrine tumors. This test supports evaluation of unexplained hypertension, palpitations, and symptoms linked to catecholamine excess.

The Chloride Random Urine Test measures chloride levels in a spot urine sample to help evaluate electrolyte and acid-base balance. Abnormal results may indicate dehydration, metabolic alkalosis, renal tubular disorders, or imbalances linked to adrenal gland conditions. This test provides clinical insight into kidney function, metabolic regulation, and systemic fluid balance by detecting changes in urinary chloride excretion.

Also Known As: Random Urine Chloride Test

The Cholesterol and Lipids Base Test evaluates key blood fats, including total cholesterol, HDL, LDL, non-HDL cholesterol, and triglycerides. It also calculates important ratios to give a clearer picture of heart health, helping identify risks and guide management of cardiovascular disease.


The HDL Cholesterol Test measures high-density lipoprotein cholesterol, often called “good” cholesterol, which helps remove excess cholesterol from the bloodstream. Higher HDL levels are linked to a lower risk of heart disease, while low levels may increase cardiovascular risk. Doctors use this blood test as part of a lipid panel to assess heart health, evaluate risk factors, and guide lifestyle or treatment strategies for cardiovascular disease prevention.

The Cholesterol Total Test measures the overall amount of cholesterol in blood, combining LDL and HDL, to evaluate cardiovascular health. High cholesterol is a major risk factor for heart disease, atherosclerosis, and stroke, while low levels may also affect health. Doctors use this test for routine screening, monitoring treatment, and assessing heart risk. Results provide key insight into lipid balance, helping guide lifestyle changes and therapy decisions.

One person dies every 36 seconds in the United States from cardiovascular disease.

That may seem like a shocking statistic, but what's more surprising is that cardiovascular disease is also the leading cause of death in the US.

Thankfully, by utilizing blood testing for cardiovascular diseases, you can learn your risk factors and make changes in your life to help prevent future heart problems.

So, what is cardiovascular disease, and which heart and cardiovascular tests are used to help diagnose it? Keep reading to learn more about this deadly disease and how to prevent it.

What is Heart and Cardiovascular Disease?

Cardiovascular disease is a type of disease that affects the heart muscle or blood vessels. Heart and Cardiovascular Disease refers to several different conditions, such as heart failure, stroke, heart attack, and more. The most common type of cardiovascular disease in the US is Coronary Artery Disease.
