NA/K Detail

The Sodium (Na⁺) and Potassium (K⁺) test is an important electrolyte panel used to assess the body's fluid and electrolyte balance. Sodium is essential for maintaining blood pressure, fluid balance, and nerve function, while potassium plays a key role in heart function, nerve signaling, and muscle contraction.

Abnormal levels of these electrolytes may indicate conditions such as dehydration, kidney disease, adrenal gland disorders, or effects from medications like diuretics. This test is commonly ordered in cases of weakness, confusion, heart rhythm problems, or suspected electrolyte imbalances to help guide diagnosis and treatment.
