Basic Metabolic Panel (BMP) with Complete Blood Count (CBC) and Hematocrit
This test measures key chemicals in your blood and evaluates your red blood cells, helping doctors check your overall health, kidney function, electrolyte balance, and blood health.
["A snapshot of your body’s chemistry and blood composition, often used for routine checks or monitoring chronic conditions."]

What This Test Measures
The **Basic Metabolic Panel (BMP)** includes tests for electrolytes like sodium, potassium, chloride, and bicarbonate, as well as blood sugar (glucose) and kidney function markers (creatinine, blood urea nitrogen). The **Complete Blood Count (CBC)** assesses red blood cells, white blood cells, and platelets, while the **hematocrit** measures the proportion of red blood cells in your blood. These together help identify imbalances in fluids, nutrients, or blood health.
Why It’s Done
Doctors order this test for general health checks, monitoring chronic conditions (like diabetes, kidney disease, or heart problems), detecting infections, or evaluating dehydration, nutritional deficiencies, or blood disorders. It’s also used before surgeries or procedures to ensure your body is stable.
Common Uses and When to Expect Results
Results are typically ready within 24–48 hours, depending on your lab. You may get them via email, portal, or a call from your doctor. Follow-up depends on your symptoms or test findings—some results may trigger immediate action (e.g., adjusting medications or fluids).
What the Results Mean
High or low values in any part of this test can signal problems like dehydration, kidney issues, electrolyte imbalances, or blood disorders. For example, very high potassium (hyperkalemia) or very low sodium (hyponatremia) can be life-threatening and require urgent treatment. Your doctor will interpret results in the context of your medical history and symptoms.
Reference range
Adult males: 38-50%; Females: 36-44%N/A
No special preparation required. Stay well hydrated.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal results can indicate underlying conditions such as diabetes (high glucose), kidney disease (elevated creatinine), anemia (low red blood cells), or infections (elevated white blood cells). Early detection allows for timely interventions, such as adjusting medications, improving hydration, or treating infections.
Short name
