What is a POTASSIUM SERUM?

Potassium Serum is a blood test that measures the level of potassium, an essential electrolyte that supports normal nerve function, muscle contraction, and heart rhythm. The test is needed to detect potassium imbalances, which may occur due to kidney disorders, certain medications, dehydration, hormonal conditions, or other illnesses. Monitoring potassium levels is particularly important in individuals with kidney disease or those taking medicines that can affect potassium balance.

FAQs

What does a high potassium level mean?

High potassium, known as hyperkalemia, may occur due to kidney problems, certain medications, hormonal disorders, or other medical conditions. Severe elevations can affect heart rhythm.

What does a low potassium level mean?

Low potassium, known as hypokalemia, may occur due to vomiting, diarrhea, excessive sweating, certain medications, inadequate intake, or hormonal conditions and can affect muscle and heart function.

What are the symptoms of high potassium?

Mild hyperkalemia may cause no symptoms. More significant abnormalities can cause muscle weakness, numbness, tingling, palpitations, or potentially serious heart rhythm disturbances.

What are the symptoms of low potassium?

Low potassium may cause muscle weakness, cramps, fatigue, constipation, abnormal heart rhythms, or palpitations. Severe deficiency can become medically serious.
