Longevity Testing SF: Science-Backed Plans at Custom Fit

The conversation around living a long life has evolved. Today, more people are focused on improving their healthspan—the number of years they live in good health—not just their lifespan. In a health-forward city like San Francisco, people are looking for smarter, data-driven ways to manage their wellness. At Custom Fit, we offer a scientific approach to longevity, using advanced testing to create health plans that are truly personalized. This article breaks down how we use tools like advanced bloodwork and genetic testing to build these effective, science-backed strategies.

What is Longevity Testing?

Longevity testing is a proactive health strategy that uses advanced diagnostics to help you understand and optimize your healthspan. The main goal is to improve your quality of life and prevent the health issues that can come with age, rather than simply trying to live longer [4]. It goes deeper than a standard physical by looking at specific biomarkers, genetic factors, and how your body functions metabolically. This gives you a clear, detailed picture of your health to build a smarter wellness plan.

The Custom Fit Difference: An Integrated, Data-Driven Approach

Data is powerful, but without an expert to interpret it and create a plan, it's just a set of numbers. At Custom Fit, our philosophy is to combine advanced testing data with personalized training, nutrition, and recovery programs led by experts. We don't believe in one-size-fits-all solutions; every plan is tailored to the individual. We use state-of-the-art technology to get results you can see and feel, creating a comprehensive approach to your wellness that leaves no stone unturned.

Core Components of Longevity Testing at Custom Fit

To create a complete picture of your health, we use a series of tests that look at your biology from different angles. This allows us to build a truly holistic strategy for you.

Advanced Bloodwork in San Francisco

Your blood offers a real-time snapshot of what’s happening inside your body. Our comprehensive bloodwork in San Francisco analyzes over 50 key biomarkers to give you objective data on your body's most important systems. The panel looks at key areas, including:

• Cardiovascular & Inflammatory Markers: Such as ApoB and hs-CRP to check your heart health risk.
• Metabolic Health & Blood Sugar Regulation: Markers like Insulin and Hemoglobin A1c that show how your body manages energy.
• Sex & Reproductive Hormones: Measuring levels of Testosterone, Estradiol, and other essential hormones.
• Thyroid Function and Nutrient Levels: Checking your thyroid and key nutrients like Iron and Ferritin.

Your results are reviewed by one of our Registered Dietitians, who helps turn the data into simple, actionable steps for your diet and lifestyle. For a more detailed review, you can discuss your results with our medical partner, Dr. Jahan Fahimi. For your convenience, we offer on-site blood draws at Custom Fit or at a nearby partner like Labcorp [8]. You can learn more about our bloodwork services on our website.

Genetic Testing for Nutrition and Performance

While bloodwork shows your health right now, genetic testing can reveal your body's underlying blueprint. Our genetic testing for nutrition in San Francisco analyzes over 70 genetic traits, giving you insights that won’t change over time. This data helps us understand things like:

• Nutrient Metabolism: How your body is built to process fats, carbs, and certain vitamins.
• Disease Risk Factors: Genetic markers linked to specific health conditions.
• Athletic Performance Predispositions: Traits related to your natural ability for endurance, power, and recovery.
• Fertility-Related Genetic Markers: Information that can be helpful for reproductive health.

With these insights, our team can design highly personalized nutrition and training strategies that work with your unique biology.

Building a 360-Degree Health Profile

To create an even more detailed plan, we use data from other key tests:

• DEXA Scan: The gold standard for measuring body composition, including body fat, muscle mass, and bone density.
• VO2 Max & RMR Testing: These tests measure your cardiovascular fitness and resting metabolism to help create effective workout and nutrition plans.
• 3D Gait Analysis: This helps find imbalances in how you move, which can improve efficiency and lower your risk of injury.
• VALD Force Deck: This technology tracks your strength, power, and balance to optimize performance and track your progress.

The Longevity Blueprint: Your All-in-One Assessment

For those who want the most complete starting point, we offer The Longevity Blueprint. This package combines our most important tests to give you a full, data-driven foundation for your health [2]. It includes:
