Why Get Blood Tests?

Doctors order blood tests for all sorts of reasons.

• Checkups: Making sure everything is running smoothly.
• Finding problems: Trying to figure out what's making you feel sick.
• Checking treatment: Seeing if your medicine is working.
• Organs: Looking at how well your liver, kidneys, and other organs are doing.

Knowing why you are getting a blood test? It helps you understand the results even better.

Different Kinds of Blood Tests

Lots of different blood tests exist. Each one looks at different stuff in your blood. Here are some of the common ones:

Complete Blood Count (CBC)

The CBC is a super common test. It tells you about the different cells in your blood. It includes:

• Red Blood Cells (RBCs): They carry oxygen.
• White Blood Cells (WBCs): These fight off germs.
• Platelets: They help your blood clot.

Knowing what a CBC looks for? It's important for understanding your blood test results. Too many or too few of these cells can mean different things.

What the CBC Numbers Mean:

• RBC Count: How many red blood cells you have. Low? Maybe anemia. High? Maybe polycythemia.
• Hemoglobin (Hb): How much oxygen your red blood cells can carry. Low? Anemia again.
• Hematocrit (Hct): What percentage of your blood is red blood cells. Low? You guessed it... anemia!
• Mean Corpuscular Volume (MCV): The average size of your red blood cells. Helps figure out what kind of anemia you might have.
• White Blood Cell Count (WBC): How many white blood cells you have. High usually means you're fighting something off.
• Differential: This breaks down the different kinds of white blood cells. It can give clues about what's causing a high WBC count.
• Platelet Count: How many platelets you have. Low means you might bleed easily. High means you might clot too easily.

Basic Metabolic Panel (BMP)

The BMP checks things like your kidney function and blood sugar. It's a key medical test to see how your body's working.

What the BMP Numbers Mean:

• Glucose: Your blood sugar. High? Could be diabetes.
• Calcium: Important for bones and muscles.
• Sodium: Helps balance fluids in your body.
• Potassium: Important for your heart.
• Chloride: Works with sodium to balance fluids.
• Carbon Dioxide (CO2): Can show problems with your kidneys or lungs.
• Blood Urea Nitrogen (BUN): Can show kidney problems.
• Creatinine: Another sign of kidney problems.

Comprehensive Metabolic Panel (CMP)

The CMP is like the BMP, but it also checks your liver. It's a good way to get a broad picture of your health. This is medical information you need to know.

What the CMP Numbers Mean (Besides the BMP Stuff):

• Alanine Aminotransferase (ALT): An enzyme in your liver. High ALT? Could mean liver damage.
• Aspartate Aminotransferase (AST): Another liver enzyme. High AST? Liver or muscle damage.
• Alkaline Phosphatase (ALP): An enzyme in your liver and bones. High ALP? Could be liver or bone problems.
• Bilirubin: A waste product the liver makes. High bilirubin? Liver or gallbladder issues.
• Total Protein: How much protein is in your blood. Can show nutrition problems or liver disease.
• Albumin: A specific protein. Low albumin? Liver or kidney disease, or maybe you're not eating enough.

Lipid Panel

This one checks your cholesterol. Good for checking your heart health!

What the Lipid Panel Numbers Mean:

• Total Cholesterol: The total amount of cholesterol.
• HDL Cholesterol: The "good" cholesterol.
• LDL Cholesterol: The "bad" cholesterol. You want this low!
• Triglycerides: Another kind of fat in your blood.

Thyroid Function Tests

Checks your thyroid hormones. Helps diagnose thyroid problems.

What the Thyroid Test Numbers Mean:

• Thyroid-Stimulating Hormone (TSH): It tells your thyroid to make hormones.
• T4 (Thyroxine): The main thyroid hormone.
• T3 (Triiodothyronine): Another thyroid hormone.

What Are Reference Ranges?

Your blood test results will show "reference ranges." These are the normal values. But remember, "normal" can be different for everyone! It depends on the lab, your age, gender, and even your race.

If your result is outside the range? It doesn't always mean something is wrong. Your doctor will look at everything to figure it out. They know how to understand your blood test results for you.

What Else Affects Your Results?

Lots of things can change your blood test results:

• Medicines: Tell your doctor what you take!
• Food: Some foods can change your blood sugar or cholesterol.
• Exercise: Hard workouts can affect some results.
• Stress: Can change your hormone levels.
• Time of day: Some tests need to be done at a certain time.
