The Serum Electrolytes test evaluates three key minerals—sodium (Na), potassium (K), and chloride (Cl)—which are essential for maintaining hydration, muscle movement, heart rhythm, and acid–base balance. Abnormal levels may indicate dehydration, kidney disease, heart problems, hormonal imbalances, or effects of medications.

Preparation: No special fasting is usually required unless advised by your doctor
Sample Type: Blood sample (from a vein in the arm)
Who Should Take It: Individuals with kidney or heart disease, dehydration, vomiting/diarrhoea, blood pressure issues, or during routine health checkups
Benefits: Detects electrolyte imbalances early, supports proper organ function monitoring, and guides timely medical treatment
