Annual Blood Tests Give a Picture of Your Health

KEY WEST, Fla., January 9, 2026 – Blood work is a standard part of an annual primary care wellness visit because it gives a global picture of your health. The lab results help your provider check for certain diseases and conditions, see indicators of your heart and organ functioning, and track how medications are working.
 
Pasquale Dell’Api, D.O., board-certified family physician at Keys Medical Group Family Medicine – Big Pine Key, says annual blood tests are important for the long term health and well-being of their patients, even when they seem to be in good health.
 
“Annual blood work measures naturally-occurring chemicals in the blood to screen for abnormalities that could signal an underlying disorder, which may not show any other signs or symptoms,” said Dr. Dell’Api. “As your results are tracked over time, we can see whether the numbers are trending in the right direction or if there is a potential condition such as diabetes or cholesterol that could benefit from treatment to prevent bigger issues later.”
 
A basic metabolic blood panel measures the amounts of eight substances in the blood and a comprehensive metabolic panel adds six more measures. The lab results give indications of the function and health of your organs, including liver and kidney, blood sugar levels, acid and base balance, fluid and electrolyte balance, and nutritional deficiencies.

• Glucose, or blood sugar levels, when elevated after fasting can be a sign of Type 2 diabetes, and very high levels whether fasting or not usually indicate Type 1 diabetes.
• Calcium is essential in your blood for proper functioning of your nerves, muscles and heart.
• Billirubin levels are an indication of how well your liver is removing the waste product from the breakdown of your red blood cells.
• Total protein in your blood helps you build muscle, heal, fight infection, and stay healthy.
• BUN (blood urea nitrogen) and creatinine levels indicate how well your kidneys are removing these waste products from the blood.
• Albumin is a protein made by your liver that transports substances through your bloodstream and keeps fluid from leaking out of your blood vessels.
• Sodium, potassium, bicarbonate and chloride are electrolytes in your blood that control nerve and muscle function and maintain the pH balance of your blood and your water balance.
• Three liver enzymes – alkaline phosphatase, alanine transaminase and aspartate amino transferase – are substances that allow certain bodily processes to happen.

 
A lipoprotein panel measures the levels of cholesterol in your blood. LDL, “bad” cholesterol, is the main source of buildup and blockages in the arteries and HDL, “good” cholesterol, helps decrease cholesterol blockages in the arteries. Triglycerides are a type of fat in your blood. If your cholesterol or triglyceride levels are outside the normal range for your gender, ethnic group and age, you may be at higher risk of heart disease.
 
Dr. Dell’Api says, “Maintaining your best health takes active work and attention as you go through life. Keeping a schedule of regular checkups and blood work can help identify any shifts in status that may call for lifestyle changes, medication or both to reverse a problem or prevent it from progressing.”
 
Even if you have never been diagnosed with a chronic illness or experienced a major medical issue, an annual checkup with your doctor supports your current health and the best actions to maintain and improve your health. Family history, lifestyle, age, diet and activity level are all factors that affect your health and your primary care provider can utilize all of that information and their knowledge to help get and keep you on track.
