The Basic Metabolic Panel (BMP) might sound modest compared to its big sibling, the CMP (Comprehensive Metabolic Panel), but don’t let the word “basic” fool you. The BMP is a widely used, clinically essential test that provides fast insight into your kidney function, blood sugar, and electrolyte balance.
If you’re being evaluated in an ER, prepping for surgery, or managing conditions like diabetes or high blood pressure, this panel is often one of the first labs ordered.
What Is a BMP?
A Basic Metabolic Panel is a blood test that includes eight components which help doctors assess your body’s chemical balance and how your organs are functioning, especially your kidneys and metabolism.
Here’s what it typically tests:
- Glucose – Blood sugar level; helps detect diabetes or endocrine problems.
- Calcium – Critical for muscles, nerves, and bone health.
- Sodium – Maintains fluid balance and blood pressure.
- Potassium – Essential for heart rhythm and muscle contraction.
- Chloride – Supports proper acid-base balance.
- Carbon Dioxide (CO₂ / Bicarbonate) – Helps maintain pH balance.
- Blood Urea Nitrogen (BUN) – Indicates protein breakdown and kidney filtration.
- Creatinine – Measures kidney function and waste filtration.
Why Do Doctors Order It?
The BMP is ordered for:
- Checking kidney function
- Managing diabetes or high blood pressure
- Monitoring electrolyte imbalances
- Pre-surgical evaluation
- Investigating symptoms like confusion, fatigue, or swelling
BMP vs CMP
The CMP includes everything in the BMP plus liver tests (like ALT, AST, and bilirubin). If liver function isn’t a concern, BMP is:
- Faster
- Less expensive
- Just as clinically relevant for many common situations
Interpreting BMP Results
Abnormal BMP values might indicate:
- High glucose → Diabetes, infection, stress
- Low sodium or potassium → Dehydration, adrenal dysfunction
- High BUN/creatinine → Kidney damage or dehydration
- Low bicarbonate → Metabolic acidosis (e.g., diabetic ketoacidosis)
Doctors look for patterns — not just one number — to diagnose and treat effectively.
Test Prep
Fasting for 8–12 hours may be required, especially for accurate glucose levels. Only drink water unless told otherwise.
Cost of a BMP
Prices can vary wildly. At RateMyLab.com, the same BMP test costs between $10 to $65, depending on the provider — for the exact same lab and report.

Who Should Get a BMP?
Consider getting a BMP if you:
- Have high blood pressure, diabetes, or kidney disease
- Need a pre-surgery evaluation
- Experience unexplained fatigue, swelling, or nausea
- Want a baseline checkup
Final Thoughts
A BMP may be called “basic,” but the information it gives is powerful. Whether you’re managing a condition or just staying proactive, this test helps ensure your body is in balance.
