Have you ever wondered what the numbers and complicated words on your blood tests mean? In this video, we will talk about the comprehensive metabolic panel, a series of blood tests that assess your body's electrolyte levels and the functioning of vital organs. These organs include the liver, kidneys, and thyroid. 

The Comprehensive Metabolic Panel (CMP Blood Test)

It is a panel of blood tests serving as an initial broad medical screening tool, including electrolyte levels and functional states of some vital organs.

Electrolyte levels. Some examples of electrolytes include sodium, potassium, and chloride. Electrolytes are tightly regulated in your body, and abnormalities in the levels of electrolytes can indicate problems.

Liver function tests

These tests indicate if your liver is working correctly or if it is inflamed or damaged. The liver filters the blood coming from the digestive tract, detoxifies chemicals, metabolizes drugs, and makes essential proteins. It is vulnerable to the toxic effects of many medications and alcohol.

Tests for liver function. These include measuring the levels of total protein and albumin—total protein. The typical range is 6.1 to 8.1 grams per deciliter. Low levels may indicate impaired liver function. Albumin. The normal range is 3.6 to 5.1 grams per deciliter. Low levels may indicate impaired liver function.

Tests for liver inflammation or damage. Increased levels of liver enzymes in the blood may indicate that they are being leaked out from damaged liver cells. AST, or aspartate amino transferase. The normal range is 10 to 35 units per liter. ALT, alanine amino transferase. The normal range is 9 to 60 units per liter. Alkaline phosphatase. The normal range is 40 to 115 units per liter.


Kidney function tests

These tests tell you if your kidneys are working properly. Kidneys filter the blood to remove waste, control your body's fluid balance, and regulate the balance of electrolytes. They are vulnerable to the toxic effects of many medications.

Creatinine serum. The normal range is 0.7 to 1.11 milligrams per deciliter. Creatinine is a breakdown product of creatine, a normal metabolic byproduct. The kidneys remove it from your body so that it can exit through the urine. An increase in blood creatinine indicates kidney disease or damage. BUN, or blood urea nitrogen. The normal range is 7 to 25 milligrams per deciliter. It measures the amount of nitrogen in your blood that comes from the waste product of urea, a breakdown product of proteins. An increase indicates kidney disease or damage.

BUN-to-creatinine ratio. This ratio may be used to determine the cause of kidney injury or dehydration. The reference ratio is 8 to 19. GFR, glomerular filtration rate. The desired level is greater than 60 milliliters per minute. A lower rate indicates kidney disease. It is often used to determine kidney failure.
