Cardiovascular lab markers, including cholesterol, LDL, HDL, triglycerides, ApoB, lipoprotein(a) and troponin. Explore available tests and how they fit into cardiovascular risk assessment.
Kidney, electrolyte, autonomic, cardiac, liver, or nervous-system-adjacent markers often need symptom timing and pacing context to become useful.
What this category can do
Cardiovascular lab markers, including cholesterol, LDL, HDL, triglycerides, ApoB, lipoprotein(a) and troponin. Explore available tests and how they fit into cardiovascular risk assessment.
Pacing
Pacing makes biomarkers and symptom timing more actionable in everyday management.
Open heart-rate pacingPEM
When symptoms escalate later rather than immediately, a recovery-oriented reading becomes more important.
Open PEM durationWhitepapers
The whitepapers connect physiology, longitudinal interpretation, and Elara’s monitoring logic.
Open whitepapersIf this category is not enough
A category page organizes markers, but many users are actually trying to answer broader questions about fatigue, PEM, pacing, or structured symptom documentation.
Questionnaires
Use validated assessments when a biomarker category alone is too narrow for the underlying question.
PEM
When symptoms worsen after activity, the timing pattern can matter more than a category label.
ME/CFS
Use the illness hub when reduced capacity, fatigue, or multisystem symptoms are part of the larger picture.

Alpha-linolenic acid (ALA) is an essential omega-3 fatty acid. This test measures its percentage in your blood.
Apolipoprotein B (ApoB) is a protein found on the surface of atherogenic lipoproteins like LDL, VLDL, and Lp(a). Measuring ApoB provides an accurate count of these particles, which is a strong predictor of cardiovascular disease risk.

Arachidonic acid is an omega-6 polyunsaturated fatty acid found in cell membranes, serving as a precursor to pro-inflammatory eicosanoids. Its blood level reflects dietary intake and metabolic status, and is assessed in cardiovascular and inflammatory conditions.

The Total Cholesterol to HDL ratio compares total cholesterol to 'good' HDL cholesterol, providing a snapshot of cardiovascular risk. A lower ratio is generally better.

DHA is an omega-3 fatty acid measured as a percentage of total fatty acids in red blood cells or plasma, reflecting dietary intake and tissue levels.
Reference: 2 - 4
Eicosadienoic acid (20:2 n-6) is a polyunsaturated omega-6 fatty acid that serves as an intermediate in arachidonic acid metabolism and is measured to evaluate fatty acid status.
Reference: 0,1–0,3 % der Gesamtfettsäuren (laborabhängig)
Eicosapentaenoic acid (EPA) is an omega-3 fatty acid. This test measures the amount of EPA in the blood, which reflects dietary intake and may relate to heart health.
Reference: 3 - 36
This test measures eicosapentaenoic acid (EPA) as a percentage of total fatty acids in the blood, providing a view of omega-3 status relative to other fats.
Reference: 0.5 - 2
Total cholesterol is the sum of all cholesterol types in your blood, essential for cell membranes, hormones, and digestion.
Reference: 0 - 200
HDL cholesterol (HDL-C) helps transport excess cholesterol from tissues to the liver for removal, supporting cardiovascular health.
Reference: 40 - 60
High-sensitivity troponin I (hs-cTnI) is a cardiac biomarker used to detect even minimal damage to the heart muscle. It is primarily used in the diagnosis of heart attacks and for risk assessment in patients with chest pain.

LDL cholesterol is a type of lipoprotein that carries cholesterol to tissues. High levels can lead to plaque buildup in arteries, increasing heart disease risk.
Reference: 0 - 155
Linoleic acid is an essential omega-6 fatty acid measured in fatty acid profiles to assess nutritional status and cardiovascular risk.
Reference: 20–40 % der Gesamtfettsäuren (laborabhängig)
Lipoprotein(a), or Lp(a), is a type of lipoprotein that carries cholesterol and fats in the blood; its levels are largely inherited and high values are an independent risk factor for cardiovascular disease.

Myristic acid (C14:0) is a saturated fatty acid measured in blood as part of a fatty acid profile. It reflects dietary intake and metabolic health.
Reference: 0,5–2,0 % der Gesamtfettsäuren (laborabhängig)
The Omega-3 Index is the percentage of EPA and DHA in red blood cell membranes, reflecting long-term omega-3 fatty acid status.
Reference: 8 - 12
The Omega-3 Index (EPA+DHA) quantifies the combined percentage of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in red blood cell membranes, a marker of long-term omega-3 status.
Reference: 8 - 12
Palmitic acid (C16:0) is the most abundant saturated fatty acid in the human body, measured to assess fatty acid metabolism and cardiovascular risk.

Triglycerides are a type of fat (lipid) found in the blood that the body uses for energy storage; high levels are linked to cardiovascular risk.

Troponin I is a heart-specific protein released into the bloodstream when heart muscle is damaged. It is the primary biomarker for diagnosing a heart attack.
Reference: 0 - 0.028
VLDL (very low-density lipoprotein) is a particle that transports triglycerides from the liver to tissues. Measuring VLDL cholesterol helps evaluate cardiovascular risk.
Reference: 5 - 40
Common markers include LDL and HDL cholesterol, triglycerides, ApoB and lipoprotein(a). Troponin is used in the assessment of suspected acute heart injury, including possible heart attack.
LDL cholesterol is a major focus in cardiovascular prevention, but targets depend on overall risk. ApoB and lipoprotein(a) can provide additional information in selected people.
