Most people are familiar with one number that defines their age: the one on their driver's license. But there is another number, a far more clinically meaningful one, that most people have never had access to.
Your biological age.
Biological age is not the number of years you have been alive. It is the age your cells, organs, and body systems are actually functioning at - based on measurable, objective data at the molecular level. Two people who are both 45 years old can have biological ages of 38 and 57 respectively. The difference between those numbers reflects not just how they feel day-to-day, but the actual trajectory of their long-term health.
At Flourish Wellness Practice in Allison Park, PA, we have partnered with TruDiagnostic, the leading laboratory in epigenetic biological age testing, to bring this technology to our patients in the Pittsburgh area. This post explains exactly what biological age testing is, how the TruDiagnostic TruAge + TruHealth Combination Test works, what the results reveal, and how we use that data to build personalized longevity protocols for our patients.
What Is Biological Age And Why Does It Matter?
To understand biological age testing, it helps to understand the science of aging itself.
For most of the twentieth century, aging was considered largely inevitable and poorly understood at the molecular level. That has changed dramatically. We now know that aging is driven by a specific set of measurable biological mechanisms and that these mechanisms can be assessed, tracked, and in many cases modified through targeted interventions.
Biological age is a composite measure of how these aging mechanisms are performing in your body right now. It integrates data from multiple systems to produce an estimate of your cellular and physiological age that is often more predictive of future health outcomes (including disease risk, cognitive decline, and longevity) than chronological age alone.
Key distinction:Chronological age tells you how long you have been alive. Biological age tells you how well your body is functioning relative to the aging process. A biological age that is lower than your chronological age suggests your body is aging more slowly than average. A biological age higher than your chronological age is a meaningful signal that something in your health, such as nutrition, stress, sleep, inflammation, toxin exposure, is accelerating the aging process and warrants attention. |
The Science Behind Epigenetic Age Testing
The most scientifically validated method for measuring biological age is epigenetic testing, specifically the analysis of DNA methylation patterns.
Epigenetics refers to changes in how genes are expressed without changes to the underlying DNA sequence itself. DNA methylation is one of the primary epigenetic mechanisms: methyl groups attach to specific sites on DNA molecules, effectively switching genes on or off. Over time, the pattern of DNA methylation across the genome changes in predictable ways that correlate with aging.
In 2013, Dr. Steve Horvath at UCLA published a landmark paper demonstrating that DNA methylation patterns could be used to accurately predict biological age across different tissues and cell types, a tool now known as the epigenetic clock. This was a pivotal moment in longevity science, and it is the foundational technology behind TruDiagnostic's testing platform.
TruDiagnostic has refined and expanded upon this technology significantly, incorporating multiple epigenetic clock models and a comprehensive multi-system biomarker analysis to produce what is currently the most complete picture of biological aging available through clinical testing.
What the TruDiagnostic TruAge + TruHealth Combination Test Measures
The TruAge + TruHealth Combination Kit analyzes over 180 biomarkers to produce a comprehensive assessment of biological aging and whole-body health. Here is a breakdown of the key components:
Biological Age Score → OMICmAge™
OMICmAge is TruDiagnostic's proprietary overall biological age calculation. It integrates multiple data points (epigenetic, proteomic, and metabolomic) to produce a single biological age estimate that is more comprehensive and accurate than any single-measure epigenetic clock. This is your primary 'bottom line' number: how old your body is functioning relative to your chronological age.
Pace of Aging → DunedinPACE™
DunedinPACE measures not just your current biological age, but the rate at which you are aging right now. Developed by researchers at Duke University, DunedinPACE indicates whether your biological aging is accelerating, stable, or decelerating. A DunedinPACE score above 1.0 means you are aging faster than one year of biological age per calendar year. A score below 1.0 means you are aging more slowly. This metric is particularly valuable for tracking the impact of lifestyle and intervention changes over time.
Organ System Age Scores — SYMPHONYAge™
SYMPHONYAge provides individual biological age estimates for 11 distinct organ systems, allowing for a precise understanding of which systems are aging well and which are under stress. The 11 systems assessed include:
Heart and cardiovascular system
Brain and neurocognitive health
Liver and metabolic function
Kidney function
Immune system and inflammation
Hormonal and reproductive health
Musculoskeletal health
Lung health
Gut and digestive system
Inflammatory and oxidative stress
Cellular energy and mitochondrial function
This is where the test becomes particularly actionable. A patient might have an overall biological age that is close to their chronological age, but an immune system age that is significantly elevated, pointing toward a specific area of focus for the healing protocol.
Additional Biomarker Analysis
Beyond the epigenetic age scores, the TruAge + TruHealth Combination Kit also measures:
NAD+ levels - a direct measure of cellular energy capacity and one of the most important biomarkers of biological aging
Inflammatory markers and immune function indicators
Cardiovascular health markers including lipid panel data
Neurocognitive health markers
Metabolic health indicators
Nutrient, vitamin, and amino acid levels
Toxin and heavy metal exposure
Stress and oxidative damage markers
How the Test Works — From Collection to Results
The testing process is straightforward and can be completed entirely at home or at our Allison Park, PA practice.
The TruDiagnostic kit uses a simple blood spot collection method. The sample is collected and sent directly to TruDiagnostic's laboratory for analysis. Turnaround time for results is approximately three to four weeks. Results are delivered through TruDiagnostic's secure patient portal and include a detailed report with all biomarker data, age scores, and percentile comparisons against age-matched reference populations.
At Flourish Wellness Practice, we do not simply hand patients their results and wish them well. Our protocol includes a dedicated results review appointment with Dr. Kate, during which we walk through every finding, explain what the data means in the context of your overall health picture, and build a personalized holistic healing protocol around your specific results.
What Happens After the Test — The Flourish Longevity Protocol
The test results are the beginning of the process, not the end. Here is how we use TruDiagnostic data to build a personalized longevity protocol at Flourish:
Step 1: Understand Your Baseline
We review your complete TruDiagnostic results together, including your biological age score, pace of aging, organ system scores, and all supporting biomarkers. We identify which systems are performing well and which are the highest priority for intervention.
Step 2: Build Your Protocol
Based on your results, Dr. Kate develops a personalized holistic healing protocol that may include targeted supplement recommendations (such as NAD+ precursors, resveratrol, or specific nutrient support based on your deficiency profile), dietary and lifestyle modifications, chiropractic and nervous system support, or sleep and stress optimization strategies.
Step 3: Implement and Track
You implement your personalized protocol with ongoing support from our team. At the 90-day mark, we conduct a follow-up appointment to assess your progress, refine your protocol based on how you are responding, and discuss whether a follow-up test to measure biological age changes is appropriate.
The complete Flourish Longevity Protocol includes:

Frequently Asked Questions About Biological Age Testing
How accurate is biological age testing?
TruDiagnostic's epigenetic testing platform is based on peer-reviewed research and is currently considered the gold standard in biological age assessment. The OMICmAge and DunedinPACE algorithms have been validated in large longitudinal studies and are used in academic research institutions worldwide. No test is perfect, but epigenetic biological age testing has demonstrated consistent correlation with health outcomes and disease risk across multiple independent studies.
How is this different from standard blood work?
Standard blood panels measure metabolic markers at a single point in time, such as cholesterol, blood sugar, thyroid function, and so on. Biological age testing measures how your cells and organ systems are aging at the epigenetic level — a fundamentally different layer of biological information. Many patients whose standard labs are 'normal' have biological ages that reveal significant accelerated aging in specific organ systems. The two types of testing are complementary, not interchangeable.
Can biological age be reversed?
Yes and this is one of the most exciting findings in longevity research. Multiple studies have demonstrated that biological age as measured by epigenetic clocks can be reduced through targeted interventions including an anti-inflammatory diet, exercise, sleep optimization, stress reduction, and specific supplements. The DunedinPACE metric from TruDiagnostic is specifically designed to detect changes in aging rate over time, making it a valuable tool for tracking the impact of longevity protocols.
How often should I retest?
For most patients implementing a new longevity protocol, retesting at 6 to 12 months provides a meaningful window to assess biological age changes. The pace of aging (DunedinPACE) can show shifts in response to interventions within shorter timeframes. Dr. Kate will discuss the appropriate retesting schedule as part of your personalized protocol.
