What This Test Measures
Your blood sample will be analyzed for a range of key chemicals, including electrolytes like sodium, potassium, and chloride, as well as substances like glucose, creatinine, and bicarbonate. These measurements help assess how well your body is maintaining proper fluid balance and filtering waste from your blood.
Common Conditions Monitored
This test can help detect or monitor conditions such as dehydration, kidney problems, high or low blood sugar, or imbalances in minerals like sodium or potassium.
Why It’s Done
Doctors may order this test if you have symptoms like unusual thirst, fatigue, swelling, confusion, or if you need to check for kidney function, fluid balance, or metabolic health before certain treatments.
Sample Collection and Preparation
A small amount of blood is drawn from a vein, usually in your arm. This is a quick and safe procedure. Your blood will be sent to a lab for testing using automated machines that analyze multiple substances at once.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
If your results are outside normal ranges, it may signal underlying health issues that need further evaluation, such as kidney disease, electrolyte imbalances, or metabolic disorders. Your healthcare provider will discuss these findings with you.
What does it mean if my sodium or potassium levels are low or high? Low or high sodium (hyponatremia/hypernatremia) or potassium (hypokalemia/hyperkalemia) can cause symptoms like muscle weakness, irregular heartbeat, or confusion. Your doctor will interpret these results in the context of your overall health.
Is there anything I should avoid before the test? Avoid strenuous activity, certain medications, or foods that might affect blood chemistry (like high-sodium or high-potassium foods) if instructed by your doctor.
