Basic Metabolic Panel BMP

Basic Metabolic Panel (BMP) 

The Basic Metabolic Panel (BMP) is a group of blood tests that provides important information about your body’s metabolism, kidney function, blood sugar levels, and electrolyte and acid/base balance. It is a commonly ordered test in routine health checkups, emergency situations, and for monitoring chronic conditions. 

1. What Is Included in a BMP? 

The BMP typically includes 8 tests: 

• Glucose – Measures blood sugar levels, important for diagnosing and monitoring diabetes. 

• Calcium – Essential for muscle function, nerve signaling, and bone health. 

• Sodium – Helps regulate fluid balance, blood pressure, and nerve/muscle function. 

• Potassium – Crucial for heart function, nerve signals, and muscle contractions. 

• Chloride – Works with sodium and potassium to maintain fluid and acid/base balance. 

• Carbon Dioxide (Bicarbonate) – Reflects the acid/base balance in the body. 

• Blood Urea Nitrogen (BUN) – Indicates kidney function and protein metabolism. 

• Creatinine – Assesses kidney function and filtration efficiency. 

2. Why Is the BMP Test Performed? 

This panel is used to: 

• Assess general health and screen for a variety of conditions. 

• Monitor people with chronic conditions like diabetes, kidney disease, or high blood pressure. 

• Evaluate symptoms such as fatigue, confusion, nausea, irregular heartbeat, or swelling. 

• Check kidney function and electrolyte levels before surgery or when taking certain medications. 

3. Reference Ranges 

Typical adult reference ranges (may vary slightly by lab): 

• Glucose: 70 – 99 mg/dL (fasting) 

• Calcium: 8.5 – 10.2 mg/dL 

• Sodium: 135 – 145 mmol/L 

• Potassium: 3.5 – 5.1 mmol/L 

• Chloride: 98 – 107 mmol/L 

• CO₂ (Bicarbonate): 22 – 29 mmol/L 

• BUN: 7 – 20 mg/dL 

• Creatinine: 0.6 – 1.3 mg/dL 

4. Interpreting BMP Results 

🔹 Abnormal glucose may indicate diabetes or hypoglycemia. 

🔹 Electrolyte imbalances can affect heart, muscle, and nerve function. 

🔹 Abnormal BUN or creatinine suggests kidney dysfunction or dehydration. 

🔹 Acid/base imbalance may be linked to respiratory or metabolic conditions. 

5. What Can Affect BMP Results? 

• Hydration status, recent food intake, medications 

• Underlying conditions like diabetes, kidney disease, adrenal disorders 

• Stress, illness, and trauma 

6. How Is the Test Performed? 

• A blood sample is drawn from a vein, often after fasting for 8–12 hours. 

• Results are typically available within a day. 

7. When to See a Doctor 

🚨 Speak with your healthcare provider if you: 

• Have symptoms related to kidney issues, electrolyte imbalances, or unexplained fatigue. 

• Have chronic conditions that require routine BMP monitoring. 

• Receive abnormal test results that require further evaluation. 

🔹 Key Takeaways 

✅ The BMP is a foundational test used to evaluate key aspects of metabolic and kidney health. 

✅ Abnormalities may signal serious health issues that require prompt attention. 

✅ It is often the first step in diagnosing and monitoring many medical conditions.
