Seven biomarkers from one drop of blood
Hemoglobin
Anemia detection
Measures oxygen-carrying capacity of your blood. Low levels may indicate anemia and explain fatigue or weakness.
White Blood Cell Differential
Infection markers
Analyzes different types of white blood cells to detect infections, inflammation, or immune system issues.
CRP
Inflammation levels
C-reactive protein indicates inflammation in your body, useful for monitoring chronic conditions.
HbA1c
Diabetes monitoring
Measures average blood sugar over the past 2-3 months, essential for diabetes management.
Ferritin
Iron stores
Indicates your body's iron reserves. Low ferritin can cause fatigue even before anemia develops.
Vitamin D
Essential nutrient levels
Critical for bone health, immune function, and mood. Many people are deficient without knowing it.
TSH
Thyroid function
Thyroid-stimulating hormone reveals how well your thyroid is working, affecting metabolism and energy.
