What Is A Biomarker? & Why Does It Matter?

Blood Data. Live Data. One Complete Picture.

Biomarker testing is the foundation of personalized health at Hundred. Biomarkers are measurable indicators in your blood, urine, and other systems that reveal how your body is functioning—across hormones, metabolism, inflammation, heart health, nutrient levels, and more.

But we believe real health clarity doesn’t come from labs alone.

At Hundred, we combine advanced lab testing with your lifestyle, goals, medical history, and wearable data to give you a complete picture of your health. This helps you understand what your results mean, why they matter, and what to do about them—so you’re never stuck with a PDF full of numbers you don’t understand.

The biomarkers we test are organized by system—making it easy to see which areas of your health need support, attention, or optimization. From hormone balance and metabolic health to cardiovascular risk and nutrient deficiencies, the list below shows everything we measure, and why it’s essential.

Whether you’re looking to feel better, age smarter, or get answers about what’s going on in your body, these biomarkers form the foundation of your personalized 100-Day Protocol.

Most people have never had a real picture of their health. Standard checkups test a fraction of what matters, flag nothing until something is already wrong, and hand you results with no explanation and no plan. OneTwenty works differently. We test the biomarkers that actually predict how you age, how you feel, and how your body is functioning right now -- across hormones, metabolism, cardiovascular health, inflammation, organ function, and more. Then we combine those results with your smart device data, lifestyle, and goals to build a protocol that's specific to your biology.

Every category below represents a system in your body. Each one tells a different part of your story. Together, they give you something most people never get: a complete, actionable picture of what's actually going on inside.

Why This Metric Is Important?

Assesses your body’s fat, muscle, bone, and water composition. Helps track weight management, hydration, and metabolic health.

Chronic low-grade inflammation is one of the biggest drivers of aging and disease. These markers reveal whether your immune system is overactive, underreacting, or silently inflamed — so you can intervene before symptoms appear.

32 biomarkers available

Immune & Inflamation

Immune & Inflammation

Immature Granulocytes (absolute and %) (female-only)

Plasma Cells (male-only)

Basophils (absolute and %)

Red Blood Cell Count

Hematocrit

Hemoglobin

Eosinophils (absolute and %)

Reactive Lymphocytes

Serum Iron

Metamyelocytes

Why This Metric Is Important?

Assesses your body’s fat, muscle, bone, and water composition. Helps track weight management, hydration, and metabolic health.

Your kidneys filter your blood continuously and regulate blood pressure, electrolytes, and waste removal. These markers catch early kidney dysfunction and hydration imbalances before they show up as symptoms.

15 biomarkers available

Kidney & Urinary

Glucose (Urine)

Urine pH

Protein (Urine)

Ketones (Urine)

Urine Color

Blood Urea Nitrogen (BUN)

Granular Casts

Hyaline Casts

Nitrites

Chloride

Why This Metric Is Important?

Assesses your body’s fat, muscle, bone, and water composition. Helps track weight management, hydration, and metabolic health.

Sleep, recovery, heart rate variability, activity, and other real-time data pulled from your connected devices. These metrics give us a continuous window into how your body is actually performing day-to-day — filling the gaps between lab draws with live signal.

22 biomarkers available

Smart Metric

Daily Step Count

Weekly Exercise Minutes

Continuous Glucose (CGM)

Muscle Mass

Lean Muscle Mass

Active Calories

Cardiorespiratory Fitness (VO₂ max estimate)

Active Minutes

Fat-to-Muscle Ratio (FMR)

Why This Metric Is Important?

Assesses your body’s fat, muscle, bone, and water composition. Helps track weight management, hydration, and metabolic health.

Hormones govern your energy, mood, metabolism, libido, sleep, and how fast you age. These markers go far beyond what your GP checks — covering testosterone, estrogen, thyroid, adrenal, and reproductive health in full.

22 biomarkers available

Hormones & Reproductive

T3 Uptake

Total T4 (Thyroxine)

Free T4 / Free T3

Thyroid-Stimulating Hormone (TSH)

Menopausal status (interpreted via FSH/LH context)

Sex Hormone Binding Globulin (SHBG) (male-only)

Hormone Replacement Therapy monitoring

Total Testosterone (male-only)

Follicle Stimulating Hormone (FSH)

Free T4 Index (T7)

Why This Metric Is Important?

Assesses your body’s fat, muscle, bone, and water composition. Helps track weight management, hydration, and metabolic health.

Most heart attacks happen in people whose standard cholesterol looked normal. These markers go deeper — assessing lipid particle size, arterial inflammation, insulin resistance, and metabolic risk years before a cardiac event.

16 biomarkers available

Cardiometabolic

Blood Pressure (both systolic and diastolic)

Resting Heart Rate

Uric Acid

Sleep Consistency (bedtime and wake-time variability)

HDL Large Particles

DPA (Docosapentaenoic Acid)

Vitamin A (Retinol)

Total Cholesterol

LDL Medium Particles

Systolic Blood Pressure

Why This Metric Is Important?

Assesses your body’s fat, muscle, bone, and water composition. Helps track weight management, hydration, and metabolic health.

Your liver processes everything you eat, drink, and absorb. These markers assess detox capacity, enzyme activity, and gut-related inflammation — catching dysfunction early before it compounds into serious damage.
