The Potassium Test measures potassium levels in blood to evaluate electrolyte balance, kidney function, and overall metabolic health. Abnormal results may indicate dehydration, kidney disease, adrenal disorders, or complications from certain medications. Doctors order this test for patients with weakness, irregular heartbeat, or high blood pressure. Results help diagnose hyperkalemia or hypokalemia and guide treatment to restore proper heart and muscle function.

The Potassium Plasma Test evaluates potassium concentration in plasma, a key marker of electrolyte status, nerve signaling, and muscle contraction. Low or high levels may reflect kidney dysfunction, adrenal imbalance, dehydration, or acidosis. This test provides insight into cardiovascular function, metabolic health, and systemic conditions affecting electrolyte regulation and overall physiologic balance.

The Potassium RBC Test measures potassium levels inside red blood cells, providing a more accurate assessment of long-term potassium status than serum testing. Potassium is essential for muscle contraction, heart rhythm, nerve signaling, and fluid balance. Abnormal results may indicate deficiency from poor diet or diuretics, or excess linked to kidney dysfunction. Doctors use this test to evaluate metabolic health and guide electrolyte management.

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 Aldosterone and Plasma Renin Activity Ratio Test measures levels of aldosterone and renin to assess adrenal and kidney function. An elevated ratio may indicate primary aldosteronism, a common cause of secondary hypertension. Doctors use this test to evaluate patients with high blood pressure, low potassium, or suspected adrenal disorders. Results help diagnose conditions like Conn’s syndrome, guide treatment, and reduce cardiovascular risks from uncontrolled hypertension.

The Electrolyte Panel Test measures sodium, potassium, chloride, and carbon dioxide in blood to evaluate fluid balance, kidney function, and acid-base status. Abnormal results may indicate dehydration, kidney disease, adrenal disorders, or respiratory issues. Doctors use this test to investigate symptoms such as weakness, confusion, or irregular heartbeat. Results provide essential insight into electrolyte balance, hydration, and overall metabolic and organ health.

The Comprehensive Metabolic Panel (CMP) Test measures 21 markers to assess metabolic health, liver and kidney function, and electrolyte balance. It includes glucose, calcium, sodium, potassium, chloride, CO2, albumin, globulin, A/G ratio, total protein, bilirubin, ALP, AST, ALT, BUN, creatinine, BUN/creatinine ratio, and eGFR. The CMP helps detect diabetes, liver or kidney disease, and supports routine screening and chronic condition monitoring.

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 Plasma Renin Activity Test evaluates how much renin the kidneys release, providing insight into blood pressure control and fluid regulation. Abnormal activity may suggest hypertension, adrenal gland dysfunction, or kidney disease. This test supports assessment of aldosterone-renin ratio, secondary hypertension, and systemic conditions that impact cardiovascular and renal health.

The Comprehensive Metabolic Panel (CMP) Plasma Test measures 21 markers of kidney, liver, and metabolic health, including electrolytes, glucose, calcium, proteins, and enzymes. Doctors order this test to evaluate conditions like diabetes, liver disease, and kidney disorders or to monitor treatment. Results provide critical insight into organ function, electrolyte balance, and overall metabolic status, guiding diagnosis, management, and preventive health care.

The Magnesium RBC Test measures magnesium inside red blood cells, providing a more accurate assessment of magnesium status than serum tests. Magnesium is vital for energy production, muscle and nerve function, heart rhythm, and bone health. Low levels may cause fatigue, cramps, arrhythmias, or weakness, while high levels may signal kidney issues. Doctors order this test to detect deficiency, monitor therapy, and evaluate overall metabolic and nutritional health.
