Description
Number of Tests Included:
Single blood test measuring serum sodium level.
What is a Sodium Test?
A biochemical test that measures the concentration of sodium in the blood to assess electrolyte balance and detect dehydration or medical conditions affecting sodium regulation.
Purpose of the Test:
Evaluate dehydration or overhydration
Diagnose kidney disorders
Detect hormonal imbalance (like adrenal or thyroid issues)
Investigate confusion, seizures, or weakness
Monitor patients on IV fluids or diuretics
Check electrolyte status in emergencies
Who Should Get This Test?
Individuals with vomiting, diarrhea, or dehydration
Patients with kidney disease
People on diuretics or BP medications
Individuals with confusion, headache, or seizures
Hospitalized or critically ill patients
Components of the Test:
Serum Sodium level (mEq/L or mmol/L)
Understanding the Test Report:
Normal: 135 – 145 mEq/L
Low Sodium (<135): Hyponatremia → causes weakness, confusion, seizures
High Sodium (>145): Hypernatremia → dehydration, kidney issues, confusion
Both low and high levels need prompt treatment.
Preparation and Procedure:
Routine blood draw
No special preparation required
How is the Test Done?
Blood is analyzed using electrolyte analyzers to measure sodium concentration.
Best Time for Test:
Anytime; emergency testing often needed during symptoms.
Booking and Checking Reports:
You can book the Sodium test via SDL, choose home sample collection, and view your digital report.
