The Kappa/Lambda Light Chains, Free with Ratio Blood Test measures free kappa and lambda light chains, proteins produced by plasma cells, and calculates their ratio. Abnormal results may indicate multiple myeloma, light chain amyloidosis, or related plasma cell disorders. Doctors use this test with serum protein electrophoresis and immunofixation to detect, diagnose, and monitor disease progression or treatment response in patients with suspected blood cancers.

The Lactic Acid Plasma Test measures lactic acid levels in the blood to help evaluate oxygen delivery, metabolic function, and tissue health. Elevated levels may signal hypoxia, sepsis, shock, heart failure, or severe infection, while mild increases can occur with intense exercise. Doctors use this test to assess critically ill patients, guide urgent treatment, and monitor metabolic or circulatory disorders for timely medical intervention.

The Lactoferrin Qualitative Stool Test measures lactoferrin in stool to assess intestinal inflammation. Positive results may signal inflammatory bowel disease, including Crohn’s disease or ulcerative colitis, while negative results often suggest non-inflammatory conditions. This test supports evaluation of gastrointestinal health, immune activity, and disorders affecting digestive function.

The Lactoferrin Quantitative Stool Test evaluates stool for lactoferrin concentration to assess inflammation in the digestive tract. Increased levels are often linked to inflammatory bowel disease, including Crohn’s disease or ulcerative colitis, while low or normal levels suggest non-inflammatory conditions. This test provides insight into immune activity, gastrointestinal health, and systemic balance.

The Lambda Light Chain Free Serum Test measures the concentration of free lambda light chains in the blood to evaluate plasma cell activity and detect abnormal immunoglobulin production. Elevated or imbalanced levels may indicate multiple myeloma, light chain disease, or other monoclonal gammopathies, helping monitor immune and bone marrow disorders.

The Lipid Panel Test checks six key blood lipids: total cholesterol, HDL cholesterol, LDL cholesterol, non-HDL cholesterol, triglycerides, and the Chol/HDL ratio. This panel assesses risk for cardiovascular disease, heart attack, and stroke by evaluating cholesterol balance and fat levels in the blood. Doctors use lipid panel results for routine screening, treatment monitoring, and guiding lifestyle or medication adjustments.

Also Known As:  Lipid Profile Test, Cholesterol Panel Test, Lipids Blood Test 

The Lipid and hs-CRP Panel is a combination of tests commonly ordered by healthcare professionals to assess an individual's risk of developing cardiovascular diseases. This panel includes the Lipid Panel and hs-CRP tests, each playing a crucial role in understanding heart health and inflammation in the body. The analysis of these markers provides valuable insights into the patient's health status, enabling early intervention and management strategies to prevent the onset or progression of diseases.

 The Lipid Panel with Direct LDL is a comprehensive blood test used to assess the levels of cholesterol and fats in the blood, which are critical indicators of heart health. This panel includes measurements of total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, non-HDL cholesterol, triglycerides, and ratios that provide insights into cardiovascular risk.

The Lipid Panel with Ratios Test measures seven key markers: total cholesterol, HDL, LDL, non-HDL cholesterol, triglycerides, Chol/HDL ratio, and LDL/HDL ratio. This advanced panel evaluates cardiovascular risk by assessing cholesterol balance and fat metabolism. Doctors use it to detect high cholesterol, atherosclerosis risk, and heart disease, and to monitor treatment. Often part of routine exams, it provides insight into long-term heart and metabolic health.

Also Known As: Lipid Profile Test, Cholesterol Panel Test, Lipid Blood Test

The Lipid Panel Test with Reflex to Direct LDL measures total cholesterol, HDL, LDL, triglycerides, and cholesterol ratios to assess heart and vascular health. If triglycerides are very high, it automatically reflexes to direct LDL measurement for greater accuracy. Doctors use this test to evaluate cardiovascular risk, guide cholesterol management, and monitor therapy. Results provide key insight into lipid balance, heart disease prevention, and metabolic health.

The Lipoprotein (a) Test measures Lp(a), a genetic form of LDL cholesterol linked to higher risk of heart disease, stroke, and atherosclerosis. Unlike standard cholesterol tests, Lp(a) levels are inherited and not easily lowered by lifestyle changes. Doctors order this test for patients with a family history of early cardiovascular disease or high cholesterol. Results help identify hidden risk, guide prevention strategies, and support heart and vascular health management.

The Lipoprotein Electrophoresis Test evaluates lipid metabolism by measuring the distribution of major lipoprotein classes such as HDL, LDL, VLDL, and chylomicrons. This test can reveal dyslipoproteinemias, detect abnormal lipid transport, and support assessment of cardiovascular and metabolic health. It offers a more detailed profile than routine cholesterol testing, highlighting underlying patterns that contribute to atherosclerosis risk.

The Lp-PLA2 Activity Test measures lipoprotein-associated phospholipase A2 enzyme activity, a marker of vascular inflammation linked to atherosclerosis and cardiovascular disease. Elevated levels may increase risk for heart attack and stroke. Doctors order this test for patients with high cholesterol, metabolic syndrome, or other risk factors. Results provide valuable insight into arterial health, helping guide prevention, treatment, and heart disease management.

The Lupus Anticoagulant Evaluation with Reflex measures PTT-LA and dRVVT to detect lupus anticoagulant antibodies, which increase risk of abnormal clotting. Reflex tests such as Hexagonal Phase Confirmation, Thrombin Clotting Time, and dRVVT mixing are performed if results are prolonged. Doctors use this panel to evaluate unexplained clotting, recurrent miscarriage, or autoimmune disease, aiding in diagnosis of antiphospholipid syndrome.

The Magnesium Micronutrient RBC Test measures magnesium levels within red blood cells, providing a more accurate assessment of long-term magnesium status than serum tests. Magnesium is vital for muscle and nerve function, energy production, bone strength, and heart health. This test helps detect deficiencies or imbalances from poor diet, absorption issues, or medical conditions, supporting overall wellness.

Patient must be 18 years of age or older.

The Magnesium RBC Test measures magnesium inside red blood cells, providing a more accurate assessment of magnesium status than serum tests. Magnesium is vital for energy production, muscle and nerve function, heart rhythm, and bone health. Low levels may cause fatigue, cramps, arrhythmias, or weakness, while high levels may signal kidney issues. Doctors order this test to detect deficiency, monitor therapy, and evaluate overall metabolic and nutritional health.

The Metabolic Syndrome & Glucose Control Panel evaluates key biomarkers—fasting glucose, insulin, lipids, and related metrics—to assess insulin resistance, glucose dysregulation, and cardiometabolic risk. This integrated panel helps clinicians identify metabolic syndrome early, monitor glycemic control, and guide interventions to reduce progression to type 2 diabetes and cardiovascular disease.

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.
