Biomarkers
Hematocrit (HTC)
Blood
Measures how much of your blood is made up of red blood cells. It’s a key indicator of oxygen delivery and can flag issues like anemia or dehydration early.
Have more energy
Improve my fitness
Hemoglobin
Blood
This oxygen-carrying protein powers your cells. Monitoring hemoglobin helps detect energy-draining issues like anemia before symptoms like fatigue and weakness appear.
Have more energy
Manage my stress and focus
Improve my digestion

Red Blood Cell (RBC) Count
Blood
Red blood cells carry oxygen. A healthy count means your body is well-oxygenated, while low or high levels can signal imbalances that affect energy, endurance, and organ function.
Have more energy
Improve my fitness
Red Cell Distribution Width (RDW)
Blood
Measures how uniform your red blood cells are. Greater variation can point to nutrient deficiencies or inflammation, often before other symptoms show up.
Have more energy
Mean Corpuscular Volume (MCV)
Blood
Tells you the average size of your red blood cells. Too large or too small often means vitamin or iron deficiencies, helping catch issues before they escalate.
Have more energy
Manage my stress and focus
Mean Corpuscular Hemoglobin Concentration (MCHC)
Blood
Shows how much hemoglobin is in each red blood cell. It helps identify anemia types and detect whether your body is transporting oxygen effectively.
Have more energy
Mean Corpuscular Hemoglobin (MCH)
Blood
Reflects the concentration of hemoglobin in red cells. It reveals how efficiently your blood delivers oxygen, helping spot deficiencies or imbalances early.
Have more energy
Platelet Count
Blood
Platelets are essential for clotting and healing. This marker helps assess bleeding risk, detect immune or bone marrow issues, and track overall health.
Improve my digestion
Stay well as I age
Mean Platelet Volume (MPV)
Blood
Tells you the average size of your platelets. Larger platelets are usually more active—MPV helps assess how your body responds to injury or inflammation.
Stay well as I age
Platelet Distribution Width (PDW)
Blood
Tracks the variation in platelet size. High PDW can signal activation or inflammation, providing insights into cardiovascular and immune health.
Stay well as I age
RDW / Platelet Ratio (RPR)
Blood
Offers an exploratory view of blood cell patterns studied in relation to liver health. Helps assess the wider picture alongside liver enzymes and the individual blood count results.
Stay well as I age
ABO Group and Rhesus (Rh) Factor
Add-on
Blood
Your blood type determines how your body responds to transfusions or organ transplants. Knowing it is essential for medical safety, pregnancy care, and planning emergencies.
