Heart & Cardiac Testing: Tests, Prices, and Risk Markers (2026)

Category hub · Updated June 9, 2026 · By the Laboratories.org editorial team

Cardiovascular disease is the leading cause of death in the United States, and blood testing is one of the primary tools for assessing risk before symptoms appear. Online lab portals offer direct access to the most commonly used cardiac blood tests — from a standard $25 lipid panel to comprehensive advanced panels. This hub explains what each test measures, when it's used, and where to find the best prices.

Key takeaways

Key cardiac blood markers explained

Lipid panel

The lipid panel measures total cholesterol, HDL ("good") cholesterol, LDL ("bad") cholesterol, and triglycerides. It is the standard first-line cardiovascular screening test. Elevated LDL and low HDL are independently associated with cardiovascular disease risk. Requires fasting for 9–12 hours before the blood draw to get accurate triglyceride and calculated LDL readings.

High-sensitivity C-reactive protein (hs-CRP)

C-reactive protein is a marker of systemic inflammation. The high-sensitivity assay can detect very low levels of CRP that correlate with cardiovascular risk — specifically, elevated hs-CRP is associated with increased risk of heart attack and stroke, even in people with normal cholesterol levels. It is commonly used alongside the lipid panel to refine risk estimates, particularly in people with borderline lipid values.

Homocysteine

Homocysteine is an amino acid produced during methionine metabolism. Elevated levels — a condition called hyperhomocysteinemia — are associated with increased risk of atherosclerosis, coronary artery disease, stroke, and deep vein thrombosis. Homocysteine elevation can also reflect vitamin B12, B6, or folate deficiency. Testing is often ordered when cardiovascular risk assessment is desired beyond standard lipid and CRP markers.

Advanced lipid panels

Standard lipid panels calculate LDL from cholesterol values, but do not measure lipoprotein particle size or number. Advanced panels (Cardio IQ, NMR LipoProfile) directly measure these parameters, which may identify high-risk individuals whose standard lipid panels appear normal. These panels cost substantially more ($134–$189) and are typically ordered at a clinician's recommendation.

Price summary by test

Test Cheapest provider Price Runner-up Price
Lipid panel (standard) LabReqs $25 Jason Health $28 (fee-inclusive)
hs-CRP Jason Health $38 (fee-inclusive) LabReqs $39
Homocysteine LabReqs $61 HealthLabs $68
Lipid + hs-CRP + Homocysteine bundle LabReqs Heart Health Panel $129 Build individually ~$127–$147

Note: Ulta Lab Tests' Homocysteine is listed at $49.90 but adds a $12.95 fee at checkout (~$62.85 total), making LabReqs at $61 the better value for homocysteine alone.

Frequently asked questions

What blood tests check heart health?

The most commonly used blood tests for cardiovascular risk are: lipid panel (cholesterol profile), hs-CRP (inflammation), and homocysteine (vascular amino acid). Advanced options like Cardio IQ panels add lipoprotein particle data. A complete metabolic panel (CMP) may also be ordered to assess liver and kidney function as part of a broader cardiovascular workup.

Can I get cardiac tests without seeing a doctor first?

Yes. All cardiac tests listed here are available through direct-to-consumer online portals. You purchase online, visit a Quest or LabCorp patient service center for a blood draw, and receive results online within 1–3 business days. See how online lab testing works for the full process.

How often should I check my cholesterol?

For adults with average risk, cholesterol screening is generally recommended every 4–6 years starting at age 20. People with elevated risk factors, family history of cardiovascular disease, or those managing high cholesterol may need more frequent testing — often annually or as recommended by a healthcare provider.

What does a high hs-CRP mean?

hs-CRP levels below 1 mg/L are considered low cardiac risk; 1–3 mg/L is average risk; above 3 mg/L is elevated risk. Levels above 10 mg/L may indicate acute infection or inflammation unrelated to cardiovascular disease. Interpretation depends on clinical context — discuss results with your healthcare provider.
