Metabolic Panel Blood Test

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

The most abundant mineral in the body, essential for bone health, muscle contraction, nerve function, and blood clotting. Blood calcium is tightly regulated by parathyroid hormone and vitamin D. Abnormal levels can indicate parathyroid disorders.

Calcium adjusted for albumin levels to provide a more accurate measure of physiologically active calcium. Important because total calcium can appear falsely low when albumin is low, even if actual calcium is normal.

An electrolyte that works with sodium to maintain fluid balance, blood pressure, and acid-base balance. Chloride abnormalities often accompany sodium abnormalities and can indicate dehydration, kidney disease, or metabolic disorders.

A waste product from normal muscle metabolism, filtered by the kidneys. Blood creatinine levels reflect kidney filtration capacity. Elevated levels may indicate impaired kidney function, dehydration, or excessive muscle breakdown.

An estimated measure of how well your kidneys filter waste from the blood. It's calculated from creatinine levels, age, sex, and race. eGFR is the primary marker used to stage chronic kidney disease.

If you have diabetes your body doesn't process glucose effectively.

Blood sugar — the body's primary energy source. Fasting glucose screens for diabetes and prediabetes. Chronically elevated glucose damages blood vessels and organs. Levels fluctuate with meals, stress, and physical activity.

Reflects your average blood sugar over the past 2–3 months by measuring the percentage of hemoglobin with attached glucose. HbA1c is the gold standard for diagnosing and monitoring diabetes, unaffected by daily fluctuations.

The hormone produced by the pancreas to regulate blood sugar. Elevated fasting insulin — even with normal glucose — is an early marker of insulin resistance, which precedes type 2 diabetes by years. Key biomarker in longevity medicine.

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.

A waste product from protein breakdown, processed by the liver and excreted by the kidneys. Elevated urea levels can indicate kidney dysfunction, dehydration, high-protein diet, or gastrointestinal bleeding.
