Cardiac Panel

A protein fragment released when blood clots dissolve. Elevated D-dimer indicates recent or ongoing clot formation and breakdown. Primarily used to rule out deep vein thrombosis and pulmonary embolism.

Erythrocyte sedimentation rate — measures how quickly red blood cells settle to the bottom of a test tube. Faster settling indicates more inflammation. ESR is a non-specific marker used to monitor inflammatory conditions like arthritis and vasculitis.

Often called 'good' cholesterol, HDL carries cholesterol away from arteries back to the liver for removal. Higher HDL levels are protective against heart disease. Exercise, healthy fats, and moderate alcohol intake can raise HDL.

Often called 'bad' cholesterol, LDL deposits cholesterol in artery walls, contributing to plaque buildup and atherosclerosis. LDL is the primary target for cardiovascular risk reduction through diet, exercise, and medication.

Involved in over 300 enzymatic reactions including energy production, muscle function, and nerve signaling. Magnesium deficiency is common and associated with muscle cramps, anxiety, insomnia, and increased cardiovascular risk.

A critical electrolyte for heart rhythm, muscle contractions, and nerve function. Both high and low potassium can cause dangerous cardiac arrhythmias. Levels are influenced by kidney function, medications, and diet.

The primary electrolyte regulating fluid balance and blood pressure. Sodium is essential for nerve impulses and muscle contractions. Abnormal levels can cause confusion, seizures, and cardiac arrhythmias.

The combined measure of all cholesterol in your blood, including HDL, LDL, and VLDL. While useful as an overview, the breakdown between HDL and LDL is more clinically meaningful for assessing cardiovascular risk.

The most common type of fat in the body, stored for energy. Elevated triglycerides — often from excess sugar, alcohol, or calories — increase cardiovascular risk and can cause pancreatitis at very high levels.
