A "7 blood test" typically refers to a Basic Metabolic Panel (BMP), sometimes called a Chem-7. This is a common group of blood tests that measures seven key substances in your blood, providing crucial information about your body's metabolism.
What does the 7 Blood Test measure?
The seven substances measured in a Chem-7 are:
- Blood Urea Nitrogen (BUN): Indicates kidney function.
- Carbon Dioxide (CO2): Shows how well your lungs and kidneys work together to maintain acid-base balance.
- Creatinine: Another indicator of kidney function.
- Glucose: Measures your blood sugar level.
- Chloride: An electrolyte vital for fluid balance and nerve function.
- Potassium: An electrolyte important for muscle function and nerve signals.
- Sodium: An electrolyte essential for fluid balance and blood pressure.
High or low levels of these substances can point to underlying health issues, requiring further investigation. A doctor will interpret the results in context with your overall health and other symptoms.
Why is a 7 Blood Test ordered?
This test is frequently ordered for various reasons, including:
- Routine checkups: To assess overall health and identify potential problems early.
- Pre-surgical screening: To ensure you're healthy enough for surgery.
- Monitoring chronic conditions: To track the effectiveness of treatment for conditions like diabetes or kidney disease.
- Diagnosing illness: To help diagnose conditions related to kidney function, electrolyte imbalances, or blood sugar control.
While some sources mention a "Basic Metabolic Panel" (BMP) as including eight substances, the Chem-7 specifically focuses on the seven listed above.
Understanding the Results
It's crucial to remember that only a doctor can interpret the results of a 7 blood test. They'll consider your individual health history and other factors to provide a proper diagnosis and recommendations.
