The Aldosterone 24 Hour Urine Test evaluates adrenal hormone output across 24 hours, offering information about blood pressure regulation, fluid balance, and electrolyte control. Elevated or low levels may suggest primary aldosteronism, adrenal tumors, or secondary hypertension. This test supports assessment of kidney function, cardiovascular health, and endocrine disorders linked to aldosterone imbalance.

The Aldosterone Test measures levels of aldosterone, a hormone produced by the adrenal glands that helps regulate blood pressure, sodium, and potassium balance. Abnormal levels may indicate primary aldosteronism, adrenal tumors, kidney disease, or secondary hypertension. Doctors use this blood test to investigate high blood pressure, electrolyte imbalances, or suspected adrenal disorders, helping guide diagnosis, treatment, and long-term patient management.

The Angiotensin Converting Enzyme (ACE) Test measures ACE levels in the blood to help diagnose and monitor sarcoidosis, a condition marked by granulomas in the lungs, lymph nodes, or other organs. Elevated ACE may also be seen in other granulomatous diseases. Doctors use this test to support diagnosis, track disease activity, and evaluate response to therapy, especially when paired with imaging or additional lab studies.

The Angiotensin II Test evaluates blood levels of a hormone central to the renin-angiotensin-aldosterone system, which regulates blood pressure and electrolyte balance. Abnormal values may indicate hypertension, kidney disease, adrenal dysfunction, or endocrine disorders. Measuring angiotensin II helps identify causes of abnormal blood pressure and supports monitoring of cardiovascular health, guiding clinical assessment of vascular and metabolic conditions.

The Antithrombin III Activity Test evaluates how effectively antithrombin controls clot formation in the blood. Reduced activity may indicate a hereditary deficiency, abnormal coagulation, or increased risk for venous thrombosis. This test provides insight into clotting disorders, supports diagnosis of thrombophilia, and helps assess vascular health and systemic risks related to impaired anticoagulant activity.

The Apolipoprotein A1 (Apo A1) Test measures levels of Apo A1, the main protein in HDL cholesterol, to assess heart and vascular health. Higher levels are linked to protective “good” cholesterol, while low levels may increase risk of heart disease, stroke, or metabolic disorders. Doctors use this test with lipid panels to evaluate cardiovascular risk, monitor therapy, and guide prevention strategies for cholesterol balance and heart health.

The Apolipoprotein A1 and B Test measures Apo A1, the main protein in HDL cholesterol, and Apo B, the primary protein in LDL and VLDL cholesterol. Together, these markers and the ApoB/A1 ratio provide a clearer picture of cardiovascular risk than standard lipid panels. High ApoB or low Apo A1 may signal heart disease, stroke, or atherosclerosis. Doctors use this test to evaluate cholesterol balance, monitor therapy, and guide prevention of cardiovascular conditions.

The Apolipoprotein B (ApoB) Test measures ApoB, the main protein in LDL and VLDL cholesterol, to assess cardiovascular risk. Elevated ApoB is linked to atherosclerosis, coronary artery disease, heart attack, and stroke. Low levels may reflect liver disease or malnutrition. Doctors often order this test with lipid panels or Apo A1 to calculate the ApoB/A1 ratio, providing a more accurate picture of cholesterol balance, cardiovascular health, and risk for heart disease.
