Blood Chemistry Tests: What Are They?

Blood chemistry tests are a group of tests that measure various chemicals in your blood. The group of tests is sometimes called the basic metabolic panel (BMP) because it includes vital information about blood glucose, calcium, and electrolytes, as well as blood tests that measure kidney function. Abnormal or irregular results can indicate a health problem that you need to address.

Blood Glucose

Blood Glucose levels are generally tested to diagnose, screen or monitor hyperglycemia, hypoglycemia, diabetes and pre-diabetes. Glucose is a form of sugar in your body that is converted to energy. Abnormal glucose levels mean your body isn't converting the sugar properly and may be an indication of diabetes. Some blood glucose tests require you to fast before your blood is drawn, while others are done immediately after a meal, or sometimes with no preparation at all.

Calcium

Calcium tests are done to evaluate whether your calcium levels are normal. Abnormal levels of this important mineral may indicate kidney problems, bone disease, thyroid disease, cancer, or malnutrition.

Electrolytes

Sodium, potassium, bicarbonate (CO2), and chloride are minerals that make up electrolytes in your body. The concentration of these electrolytes is regulated by your body. Electrolyte imbalances can indicate a variety of acute and chronic illnesses, including dehydration, kidney disease, liver disease, heart failure, or high blood pressure.

Kidneys Kidney blood chemistry tests measure levels of blood urea nitrogen (BUN) and creatinine. This test evaluates kidney function and monitors the effectiveness of dialysis or other treatments for kidney disease. BUN and creatinine are waste products filtered from the blood by the kidneys. Increased levels of BUN and creatinine may indicate chronic or temporary kidney problems. If a doctor wants more in-depth information, he or she may order a Complete Metabolic Panel (CMP), a group of 14 tests that includes the BMP.
