From blood pressure to cholesterol, biomarkers are at the heart of how we understand and manage our health. With the rise of personalized medicine and at-home diagnostics, testing key biomarkers has never been more accessible.
One powerful example of this shift is the Everlywell 360 Full Body Test, a comprehensive tool designed to help you measure and track vital health indicators from the comfort of home.
Here, we’ll decode the different types of biomarkers, explore their roles in health and disease, and show how Everlywell’s 360 test empowers you to track the most meaningful indicators of your well-being.
A biomarker, short for biological marker, is a measurable indicator of a biological process, condition, or disease. Biomarkers can be found in your blood, tissues, and organs, or even in data collected from wearables and imaging scans.[1]
They’re used to diagnose illness, assess disease risk, monitor how well treatments are working, and guide therapeutic decisions.[1] Whether it’s blood pressure, blood sugar, or PSA levels, biomarkers help bring clarity to what’s happening inside the body.
In medicine, biomarkers play essential roles across:
In the age of precision medicine, biomarkers also help tailor treatments to your biology. That’s especially important in areas like cancer treatment, where therapies can be guided by biomarkers like HER2, BRCA, or EGFR.[2]
According to the FDA and NIH, biomarkers fall into seven primary categories based on their clinical use:[1,3]
Biomarkers can also be grouped by what they measure and how they’re collected:[4]
Even common metrics, such as BMI or resting heart rate, can serve as risk biomarkers, although they may not always provide the precision of molecular data.
The Everlywell 360 Full Body Test includes many biomarkers that serve as key indicators of foundational health. Here are several you can track regularly:
Biomarker | Type | Clinical Use |
---|---|---|
HbA1c | Monitoring | Blood sugar control and diabetes risk[5] |
hs-CRP | Monitoring/Risk | Inflammation and cardiovascular risk[6] |
Total Cholesterol, LDL | Diagnostic/Risk | Heart disease and metabolic syndrome[7] |
ALT, AST | Safety | Liver health and medication response[8] |
TSH, Free T3, Free T4 | Diagnostic | Thyroid disorders[9] |
Cortisol | Prognostic/Monitoring | Stress and adrenal function[10] |
Vitamin D | Risk/Monitoring | Immune support, bone health[11] |
Tracking these markers can help uncover trends early, before symptoms appear, and provide the information you need to partner with your provider in developing a personalized plan.
Biomarkers are crucial in managing complex conditions, including cancer, autoimmune diseases, and heart disease.
For example, in small cell lung cancer, researchers use multiple biomarkers, like tumor mutational burden (TMB), circulating tumor DNA (ctDNA), and prognostic markers, to predict treatment outcomes and monitor disease progression.[12]
Similarly, inflammatory markers like hs-CRP and lipid profiles are widely used to assess risk and response in cardiovascular disease.[6]
Tracking your biomarkers could mean catching health issues early, before they progress into more serious conditions.
