A Basic Metabolic Panel (BMP) is a blood test that measures several substances to check your body's fluid balance, electrolyte levels, blood sugar, and kidney function. It is often ordered during a routine checkup or when you have symptoms like fatigue, confusion, or swelling.
What it measures
- Sodium — Helps control fluid balance and nerve function.
- Potassium — Important for heart and muscle function.
- Calcium — Needed for bones, muscles, and nerves.
- Glucose — Your main source of energy; high levels can suggest diabetes.
- Blood urea nitrogen (BUN) — A waste product that shows how well your kidneys are working.
- Creatinine — Another waste product used to check kidney function.
Who it is for
A doctor or other healthcare provider typically orders a BMP as part of a routine exam or to monitor conditions like kidney disease, high blood pressure, or diabetes.
Preparation
You may need to fast (not eat or drink anything except water) for 8 to 12 hours before the test, but often no fasting is required. Follow your provider's instructions.
Results and what they mean
Results are usually available in 1 to 3 business days and are reported as numbers with a reference range. A clinician interprets these results based on your health history, so do not use them to diagnose yourself. This is general information, not medical advice.

Frequently asked questions
Does a BMP hurt?
You may feel a quick pinch when the needle goes in, but the test itself is very short.
Can I drink water before the test?
Yes, unless your provider tells you otherwise. Water is usually fine and helps with the blood draw.
What if my results are outside the normal range?
Many factors can affect results. Your provider will explain what your numbers mean for you.
How often should I get a BMP?
It depends on your health. Some people get it yearly, while others may need it more often. Ask your provider.
