You probably know that getting your blood drawn each year is a good idea—but have you ever wondered what exactly doctors are looking for in those vials? Annual blood tests can reveal a wealth of information about your overall health, from how your organs are functioning to your risk for certain chronic diseases. They can detect problems early, sometimes before you even feel a symptom, making them one of the most powerful tools in preventive medicine.
At Genesis Lifestyle Labs, we believe that knowledge is power—especially regarding your health. Our range of lab testing services, from basic hormone checks to full metabolic panels, give you deeper insight into your body. In this article, we explain exactly what shows up in a typical annual blood test and why staying proactive with routine testing is essential.
What does an annual blood test identify?
Annual blood work is a roadmap for your health. These tests provide crucial information that helps you and your provider understand how your body is functioning and catch any warning signs early. Think of it as a regular check-in that can guide you toward better habits, treatments, or lifestyle changes before small problems become serious.
Let’s look closer at the key markers an annual blood test can reveal—and what they say about your overall well-being.
Cholesterol levels
One of the most common things measured is your cholesterol profile, which includes HDL (the "good" cholesterol), LDL(the "bad" cholesterol), and triglycerides. High LDL and triglyceride levels can raise your risk of heart disease, stroke, and atherosclerosis. Your HDL, on the other hand, helps protect your heart by clearing excess cholesterol from your arteries.
Blood sugar and insulin levels
Annual blood tests often include a fasting blood glucose test or HbA1c, which indicates how well your body manages blood sugar. These values are critical for detecting prediabetes and type 2 diabetes or monitoring the management of diabetes. Elevated levels can be a warning sign that it’s time to adjust your diet, exercise, or medication.
Liver function
Liver panels assess key enzymes and proteins such as ALT, AST, ALP, and bilirubin. These markers help determine how well your liver is working and whether there’s any damage or inflammation. Liver function can be impacted by medication use, alcohol, infections like hepatitis, or metabolic conditions.
Kidney function
Your kidneys are responsible for filtering waste from your blood. An annual blood test will typically include creatinine and BUN (blood urea nitrogen) to evaluate kidney performance. Abnormal values may point to early-stage kidney disease or dehydration.
Electrolytes and minerals
Levels of sodium, potassium, calcium, and other minerals help assess your hydration, heart function, muscle health, and more. Imbalances can occur from medications, kidney issues, or underlying medical conditions.
Complete blood count (CBC)
The CBC measures your red and white blood cells and platelets. It provides insights into oxygen transport, immune function, and blood clotting. Abnormalities may indicate anemia, infection, inflammation, or bone marrow issues.
Thyroid function
Many annual tests now include TSH (thyroid-stimulating hormone) along with T3 and T4. These hormones regulate metabolism, energy levels, weight, and mood. Abnormalities could signal hypothyroidism or hyperthyroidism.
Inflammation and heart risk markers
Some panels also test for CRP (C-reactive protein) or BNP (B-type natriuretic peptide), which can help identify inflammation or stress on the heart. Elevated CRP can be linked to cardiovascular risk, while high BNP may suggest heart failure.
Stay proactive with your health with blood tests
While annual blood testing is a great start, many health markers can change more frequently depending on your lifestyle, age, and personal risk factors. Blood tests aren't just a once-a-year thing—they can be an essential tool for staying on top of your health all year long. Whether you’re beginning a new fitness program, managing a chronic condition, or optimizing your hormones, regular blood work helps you make informed decisions.
From hormone fluctuations to early signs of chronic illness, these tests offer real-time insight into your body’s internal systems—empowering you to make proactive decisions
Hormone imbalances
Hormones like testosterone, estrogen, progesterone, DHEA, and SHBG can fluctuate based on stress, age, and lifestyle. Imbalances can lead to fatigue, mood swings, weight gain, sleep problems, or low libido. Our Genesis Men Hormone Check Panel and Genesis Women Hormone Check Panel provide comprehensive insights into your hormonal health.
Metabolic function
If you’re actively managing your weight, tracking your insulin, glucose, and lipid panel more often than once a year can help you understand how your metabolism is functioning. This is especially important if you’re making dietary or exercise changes and want to measure their impact. Our Genesis Ultimate Hormone Panel includes metabolic markers alongside hormones for a full-body picture that helps you make proactive changes to your plan.
Growth and aging
IGF-1 (Insulin-Like Growth Factor 1) is a marker related to growth hormone levels and can indicate how well your body is recovering and aging. Low levels may be associated with poor muscle growth, fatigue, or age-related decline. The IGF-1 Lab Test is ideal for those focused on longevity and performance.
