Comprehensive blood test to analyze electrolyte levels and assess bodily functions.
This test measures the levels of vital salts and minerals (sodium, potassium, calcium, chloride) in your bloodstream. Electrolytes are crucial for nerve impulse conduction, muscle contractions, and maintaining blood acid-base balance. This test is essential for individuals with specific health conditions or those taking certain medications that may affect electrolyte balance. Regular monitoring helps detect imbalances early, allowing for timely intervention and lifestyle adjustments. Results are available on our free Health Dashboard.
Key Details
Who Is This For?
People taking diuretics, blood pressure medications, or other drugs that affect electrolyte balance. Athletes and endurance sport participants concerned about hydration and mineral loss. Anyone experiencing muscle cramps, weakness, irregular heartbeat, or confusion. Patients with kidney disease, heart failure, or liver disease who need regular monitoring.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
5The 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 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.
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.
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 key component of the body's acid-base buffering system. Bicarbonate levels reflect the balance between acids and bases in the blood. Abnormal values help diagnose metabolic acidosis or alkalosis.
