Receiving your lab test results can sometimes feel confusing or even stressful. With so many numbers, abbreviations, and reference ranges, it’s easy to wonder what it all means and whether you should be concerned.
At Blue Point Medical Group, we believe understanding your lab results is an essential part of staying informed about your health. This guide will walk you through the most common blood tests, what they measure, and how to interpret your results in a clear, simple way.
Why Lab Results Matter
Laboratory testing plays a vital role in preventive care, diagnosis, and treatment. These tests help your healthcare provider evaluate how well your body’s organs and systems are functioning. They can detect early signs of disease, track chronic conditions, and ensure your treatments are working effectively.
When considered alongside your medical history, lifestyle, and symptoms, lab results provide a complete picture of your overall health.
How to Read Your Lab Report
Your lab report includes several key sections:
- Test Name: The name of the specific test performed, such as “Complete Blood Count (CBC)” or “Lipid Panel.”
- Result: Your personal measurement.
- Reference Range (Normal Range): The values expected in healthy individuals.
- Units of Measurement: The metric used to express your results.
- Flag or Indicator: A symbol (like “H” for high or “L” for low) that shows whether your result falls outside the normal range.
It’s important to remember that “normal” can vary slightly depending on the laboratory, your age, sex, and health status. A result outside the reference range doesn’t always mean something is wrong; your provider will interpret results in context.
Complete Blood Count (CBC)
The Complete Blood Count, or CBC, is one of the most common and informative blood tests. It measures various components of your blood to evaluate your immune system, oxygen levels, and overall health.
Here’s what it includes:
- Red Blood Cells (RBC): Carry oxygen throughout your body. Low levels may suggest anemia, while high levels could indicate dehydration or other conditions.
- White Blood Cells (WBC): Help fight infection. A higher count may signal infection or inflammation; a low count can indicate a weakened immune system.
- Hemoglobin (Hgb) and Hematocrit (Hct): Measure oxygen-carrying capacity and blood concentration.
- Platelets: Help with blood clotting. Low platelet levels can increase bleeding risk; high levels may require further testing.
Comprehensive Metabolic Panel (CMP) and Basic Metabolic Panel (BMP)
These panels assess electrolytes, kidney, and liver function. They provide insight into how your organs are performing and how well your body maintains balance.
Key measurements include:
- Glucose: Measures blood sugar levels. High glucose can indicate diabetes or insulin resistance.
- Calcium: Important for muscle and nerve function. Abnormal levels can signal bone or thyroid problems.
- Sodium, Potassium, and Chloride: Electrolytes that regulate hydration, muscle function, and blood pressure.
- Blood Urea Nitrogen (BUN) and Creatinine: Indicators of kidney function. Elevated levels can suggest dehydration or kidney issues.
- Liver Enzymes (ALT, AST, ALP): High levels may indicate liver disease or damage.
Lipid Panel
A Lipid Panel measures fats and cholesterol in your blood, helping assess your risk for heart disease.
- Total Cholesterol: Measures the total amount of cholesterol in your blood.
- LDL (“Bad” Cholesterol): High levels can lead to plaque buildup in your arteries.
- HDL (“Good” Cholesterol): Helps remove excess cholesterol from your bloodstream.
- Triglycerides: A type of fat that can increase heart disease risk when elevated.
Your provider may recommend lifestyle changes or medication if your cholesterol levels are too high.
Thyroid Function Tests
Your thyroid gland regulates metabolism, energy, and body temperature. Standard thyroid tests include:
- TSH (Thyroid Stimulating Hormone): High levels may indicate an underactive thyroid; low levels can signal overactivity.
- Free T4 and Free T3: Measure actual thyroid hormone levels circulating in your blood.
Abnormal results help diagnose conditions like hypothyroidism or hyperthyroidism.
A1C and Blood Sugar Tests
For patients with diabetes or at risk of developing it, these tests are essential:
- Fasting Blood Glucose: Checks your blood sugar after not eating for at least 8 hours.
- A1C Test: Measures your average blood sugar over the past 2–3 months, providing a longer-term view of glucose control.
Your provider uses these results to monitor diabetes management and medication effectiveness.
Understanding “Abnormal” Results
Seeing “high” or “low” on your lab report doesn’t always mean you’re unhealthy. Results can be affected by medications, diet, hydration, stress, or temporary illness.
Your provider will consider:
- Your overall health and medical history
- Any symptoms you’re experiencing
- Whether follow-up testing is needed
Sometimes, slight variations are typical for your body. However, consistent abnormal results may require additional evaluation.
What to Do If You Don’t Understand Your Results
If your results seem confusing, don’t worry—you’re not alone. At Blue Point Medical Group, our providers take time to explain your results clearly, answer your questions, and discuss any next steps.
Here are some tips for reviewing your lab report:
- Ask about each abnormal value: What does it mean, and how does it affect your health?
- Track your results over time: Small changes can reveal significant trends.
- Avoid self-diagnosing: Online research can be misleading without professional guidance.

When Additional Testing Is Needed
Sometimes, a single test doesn’t provide the whole picture. Your doctor may recommend:

This step ensures your care plan is personalized and precise.
