Immune Age Test: Determine Your Immune System's Age

Do you ever feel older or younger than your driver's license age? Your chronological age, which is the number of birthdays you've had, is only part of the story. Your biological age represents your body's true condition at the cellular level, offering a more accurate picture of your health and longevity potential than your birth year.

While biological age encompasses your entire body, your immune system plays a crucial role in determining your health trajectory. Immune age refers to the functional age of your immune system and predicts your healthspan, which is the years you will live in good health. An immune age test is a key step in preventive health, providing early insight into your body's ability to fight disease, resist infections, and maintain wellness.

Generation Lab's SystemAge test, a breakthrough that brings clinical-grade diagnostics to your home. This advanced at-home test measures your immune age alongside 18 other organ systems, empowering you to control your health before symptoms appear and optimize your biology for a longer, healthier life.

What is Immune Age?

Think of it like a car. The model year is its age, but mileage and engine condition determine its performance. Your immune age is your engine's condition; it indicates your immune system's functioning regardless of your age. Two 50-year-olds can have different immune ages: one might have the immune function of a 35-year-old, while another might have the compromised immunity of a 65-year-old.

As we age, our immune system undergoes two processes that accelerate aging. Immunosenescence refers to the deterioration of the immune system, while inflammaging describes chronic, low-grade inflammation that drives aging. When your immune age exceeds your chronological age, these processes accelerate, increasing your risk for age-related diseases, infections, and cancer.

Understanding your immune age is a critical health marker for several reasons:

• Predicts Healthspan: A younger immune age is linked to a longer healthy, active life free from chronic disease.
• Early Disease Detection: An elevated immune age can signal chronic conditions years before symptoms manifest.
• Infection Resilience: Your first and strongest defense against viruses, bacteria, and other pathogens is a strong, youthful immune system.
• Cancer Surveillance: A well-functioning immune system is effective at identifying and eliminating pre-cancerous cells before they develop into tumors.

How Immune Age Testing Works

Traditional blood tests provide useful snapshots of your current health, but they don't measure the biological processes that drive aging at the cellular level. To understand your immune age, we need to look at epigenetics, which is the science of how your behaviors, environment, and lifestyle can cause changes that affect gene function without altering the DNA sequence.

The most accurate method for measuring biological age involves analyzing DNA methylation patterns throughout your genome. DNA methylation acts as a system of molecular switches that turn genes "on" or "off." In a young, healthy body, these switches operate in organized, predictable patterns. As we age, these patterns become disorganized or "noisy." This phenomenon, which is called biomolecular noise, is a hallmark of aging. Epigenetic age testing via DNA methylation analysis represents the gold standard for biological age measurement, pioneered by researchers at Harvard and UC Berkeley.

Advanced DNA methylation tests can analyze hundreds of thousands of methylation sites across your genome, creating a high-resolution picture of your molecular aging process. This technology enables us to move beyond simple biological age calculations to provide detailed, organ-specific aging analysis that gives you precise insight into how each system in your body is aging biologically.

The Best Immune Age Testing: SystemAge

Generation Lab is a cutting-edge longevity science company co-founded by UC Berkeley professor Dr. Irina Conboy, known as the "mother of longevity" for her groundbreaking aging biology research. The SystemAge test represents over 20 years of Harvard and UC Berkeley research, bringing clinical-grade diagnostics with unprecedented precision to your home.

Your Body's 19 Biological Ages

SystemAge is the first and only test providing individual biological ages for 19 organ systems. This organ-specific aging analysis represents a revolutionary advancement in personalized health assessment. Knowing your overall biological age is helpful, but understanding that your heart might be aging faster than your brain, or that your immune system is functioning like someone 10 years younger, provides actionable intelligence for targeted interventions.

Your SystemAge report includes biological age analysis for these 19 critical systems:

• Immune
• Cardiovascular
• Nervous
• Musculoskeletal
• Respiratory
• Digestive
• Endocrine
• Reproductive
• Urinary
• Integumentary
• Lymphatic
• Hepatic
• Renal
• Pancreatic
• Thyroid
• Adrenal
• Pituitary
• Gonadal
• Metabolic

Clinical-Grade Accuracy, Validated by Science

SystemAge delivers unprecedented precision through the analysis of 460+ DNA methylation biomarkers, achieving 99% accuracy in detecting biological age changes. This has been validated across 1,600+ clinical test cases. The founding team's research includes 20+ peer-reviewed publications in top-tier journals like Nature, Aging, and GeroScience, earning over 14,000 scientific citations.

This precision and credibility is why SystemAge has earned the trust of over 150 longevity clinics worldwide and endorsements from leaders, including Harvard geneticist George Church. Choosing SystemAge gives you access to the same testing used in cutting-edge research institutions and premier longevity clinics.

4. Get Your Results: Within 3-4 weeks, you'll receive your comprehensive digital report detailing your 19 biological ages through our secure online portal.

Why SystemAge is the Most Accurate Biological Age Test

When choosing a preventive health testing solution, precision and comprehensiveness determine the value you receive. Here's how SystemAge compares to other options:

SystemAge vs. TruDiagnostic:

• SystemAge provides 19 organ system reports for complete health analysis with 99% accuracy.
• TruDiagnostic offers fewer organ scores (~11 systems) with lower reported accuracy (~58%).

SystemAge vs. Function Health:

• SystemAge uses deep epigenetic analysis to detect "biomolecular noise" and predict health risks years before symptoms.
• Function Health: Relies on 100+ standard blood biomarkers that reveal current health status but miss subtle epigenetic changes that predict future disease risk.

SystemAge vs. Tally Health:

• SystemAge: Uses blood samples (the gold standard for DNA methylation analysis) backed by Dr. Conboy's 20+ years of pioneering aging research.
• Tally Health: Uses cheek swab collection, which can be less reliable for systemic aging analysis despite notable scientific backing.

SystemAge is the only clinical-grade test that combines organ-specific analysis across 19 systems with 99% accuracy. It enables personalized and measurable interventions for biological age reversal.

Conclusion

Your age isn’t just an unchangeable number, it’s a dynamic biological process you can influence and optimize. The SystemAge immune age test provides the data and personalized action plan you need to transform aging from a passive process into one you can control and reverse.

Every day matters in your biological aging journey. The earlier you establish your baseline and begin targeted interventions, the more dramatic your potential improvements. Don't wait for symptoms or your next birthday to remind you that time is passing.
