When you receive pathology results from your doctor, it’s easy to assume that the “normal” ranges provided by your lab report are indicative of optimal health. However, it’s important to understand that these ranges are based on averages from a large, often diverse (and relatively unhealthy) population. They aren’t necessarily reflective of the ideal levels for individual health or well-being. In fact, a "normal" result can sometimes mask an underlying health issue, especially if you’re on the borderline of the range.
Blood Ranges Are Based on Population Averages, Not Optimal Health
Blood pathology ranges are determined by measuring the values of specific markers (such as cholesterol, glucose, or vitamin D levels) across a broad population. The goal is to capture what is statistically typical for most people. This means that if you fall within the "normal" range, it doesn't automatically equate to the best or most optimal state for your body.
For example, cholesterol levels may be considered "normal" if they fall within a certain range, but a person at the upper end of that range might still be at increased risk for cardiovascular disease. Similarly, vitamin D levels might be deemed sufficient by the lab's standards, but they could still be suboptimal for immune health or bone density. This is why AstonRX provides you with a full explanatory report to help you understand your blood test results, as well as the target ‘optimal’ range, not just community averages.
Blood Tests Don’t Measure Everything
Another important consideration is that blood tests don’t measure all health markers. Standard testing typically focuses on a set of key markers—such as red and white blood cell counts, glucose, cholesterol, liver and kidney function, etc.—that are deemed necessary by the physician based on your symptoms or medical history.
If you're seeing a general practitioner or primary care doctor, they will usually only order tests for specific markers that they believe are relevant to your health at that time. If you're on Medicare or another insurance program, the doctor needs to justify the need for specific tests, and the coverage may be limited to what is deemed medically necessary for your current condition.
Preventative Health Starts with Regular Testing
To truly optimise your health, especially for long-term prevention, it’s important to measure a broader range of metabolic markers on a regular basis. A general blood test profile and key metabolic markers—like inflammation markers, lipids (triglycerides/cholesterol) blood glucose management, and vitamin/mineral deficiencies—should ideally be measured at least once a year, rather than waiting until you're feeling unwell. Early detection of subtle imbalances can help prevent more serious health conditions from developing down the line.
While blood tests alone aren’t a magic solution, regular monitoring is a powerful tool for maintaining health and identifying potential risks before they become problems. Don’t just rely on “normal” ranges—take charge of your health by proactively managing your blood markers for a more comprehensive view of your well-being.
