Demystifying Common Lab Tests: What Your Blood Work Results Mean

At Harris Functional Medicine, we believe that understanding your health starts with understanding your lab results. That's why we offer in-office lab testing and take the time to help our patients interpret their test results. In this blog, we'll demystify some common blood work tests and explain what those numbers on your lab report really mean.

The Importance of Lab Testing

Regular blood work is a crucial part of preventive care and ongoing health management. These tests can:

- Detect potential health issues before symptoms appear

- Monitor existing conditions

- Guide treatment decisions

- Track the effectiveness of medications or lifestyle changes

Common Blood Tests and Their Meanings

Complete Blood Count (CBC)

A CBC provides information about your blood cells, including red blood cells, white blood cells, and platelets.

Key components:

- Red Blood Cell Count: Indicates oxygen-carrying capacity

- White Blood Cell Count: Reflects immune system function

- Hemoglobin: Measures oxygen-carrying protein in red blood cells

- Hematocrit: Percentage of blood volume composed of red blood cells

Abnormal results might indicate conditions like anemia, infection, or blood disorders.

Lipid Panel

This test measures various types of fats in your blood, crucial for assessing heart health.

Key components:

- Total Cholesterol: Overall level of blood cholesterol

- LDL Cholesterol: Often called "bad" cholesterol

- HDL Cholesterol: Often referred to as "good" cholesterol

- Triglycerides: A type of fat in the blood

High levels of LDL or triglycerides, or low levels of HDL, may indicate increased risk for heart disease.

Comprehensive Metabolic Panel (CMP)

The CMP provides information about your body's chemical balance and metabolism.

Key components:

- Glucose: Blood sugar level

- Electrolytes: Sodium, potassium, chloride, and bicarbonate levels

- Calcium: Important for bone health and other bodily functions

- Liver enzymes: Indicators of liver function

- Kidney function tests: Creatinine and BUN (blood urea nitrogen)

Abnormalities in these tests can indicate a wide range of conditions, from diabetes to liver or kidney disease.

Thyroid Function Tests

These tests assess how well your thyroid gland is working.

Key components:

- TSH (Thyroid Stimulating Hormone): The primary screening test for thyroid function

- T4 and T3: Thyroid hormones

Abnormal levels may indicate conditions like hypothyroidism or hyperthyroidism.

Hemoglobin A1C

This test provides information about your average blood sugar levels over the past 2-3 months.

- A result below 5.7% is considered normal

- 5.7% to 6.4% indicates prediabetes

- 6.5% or higher suggests diabetes

Understanding Your Results

It's important to remember that lab results are just one piece of the health puzzle. Factors like age, gender, medical history, and current medications can all influence what's considered "normal" for you.

At Harris Functional Medicine, we don't just look at whether your results fall within the standard reference range. We consider optimal ranges for health and longevity, which may be narrower than standard ranges.
