Understanding Lab Tests for Heart Disease
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Heart disease encompasses various conditions affecting the heart and blood vessels, including coronary artery disease, heart attacks, and stroke. While heart disease is diagnosed through a combination of clinical evaluation, imaging, and other specialized tests, blood tests play a crucial role in assessing cardiovascular risk factors and monitoring heart health.
Top Recommended Test
Lipid Panel
This fundamental test measures cholesterol levels, including HDL (good cholesterol). Low levels of HDL cholesterol can increase the risk of heart disease, making this test essential for cardiovascular risk assessment.

Why Blood Testing is Important for Heart Health
Blood tests are fundamental for evaluating cardiovascular risk by measuring cholesterol levels, inflammation markers, and other factors that contribute to heart disease development. These tests help healthcare providers assess your risk profile, guide preventive measures, and monitor the effectiveness of treatments designed to protect heart health.
Other Relevant Tests
Lipid Panel with Ratios
This comprehensive test provides additional risk assessment through cholesterol ratios and non-HDL cholesterol measurements. A high cholesterol-to-HDL ratio indicates higher heart disease risk, while elevated non-HDL cholesterol represents all the 'bad' types of cholesterol that can contribute to cardiovascular problems.

Cardio IQ Advanced Lipid Panel
This advanced test provides detailed analysis of cholesterol particle sizes and types. It measures small dense LDL particles and large HDL particles, offering a more precise assessment of cardiovascular risk. Higher concentrations of small dense LDL particles and lower levels of large HDL particles can significantly increase heart disease risk.

C-Reactive Protein (CRP)
CRP is a key inflammation marker that indicates potential cardiovascular risk. High levels of CRP can signal inflammation in blood vessels, which is a significant contributor to heart disease development and progression.

Folate (Folic Acid)
This test measures folate levels, which are important for cardiovascular health. Low folate levels can lead to increased homocysteine, an amino acid that has been linked to higher risk of heart disease when elevated.

Gamma Glutamyl Transpeptidase (GGT)
Research indicates that elevated GGT levels may be associated with increased heart disease risk. While the exact relationship is still being studied, this test can provide additional insight into cardiovascular risk assessment.
