What are Blood Biomarkers?
ABO Group and Rhesus (Rh) Factor
This test identifies your blood type (A, B, AB, or O) and whether you have the Rh factor (positive or negative). It’s essential in emergencies, during pregnancy, and for blood donation.
Example: Knowing your blood type is like knowing your body’s fuel type—critical for safe transfusions and pregnancy health.
How it’s measured: Blood test that determines your ABO group and Rh factor.
Hematocrit (HCT)
HCT measures what percentage of your blood is made up of red blood cells. It helps detect anemia, dehydration, or bone marrow disorders.
Example: Think of hematocrit like measuring the juice content in a smoothie—too little means it’s watered down (anemia), too much could be too thick (polycythemia).
How it’s measured: Part of a Complete Blood Count (CBC) blood test.
Hemoglobin
Hemoglobin is the oxygen-carrying part of red blood cells. Low levels may indicate anemia, vitamin deficiencies, blood loss, or chronic disease.
Example: Hemoglobin is like your body’s oxygen delivery truck—if there aren’t enough, your cells go hungry.
How it’s measured: Blood test (part of CBC).
Mean Corpuscular Hemoglobin Concentration (MCHC)
MCHC shows how concentrated hemoglobin is within your red blood cells. It helps detect anemia or conditions like hypothyroidism and spherocytosis.
Example: MCHC is like testing how much paint is packed into each balloon—too little = weak cells.
How it’s measured: Calculated as part of a CBC test.
Mean Corpuscular Hemoglobin (MCH)
MCH measures the average amount of hemoglobin per red blood cell. It can reveal vitamin or iron deficiencies, chronic disease, or blood loss.
Example: MCH is like checking how much fuel each red blood cell carries—too little and they can’t deliver oxygen properly.
How it’s measured: Blood test (part of CBC).
Mean Corpuscular Volume (MCV)
MCV measures the average size of red blood cells. Abnormal size can reveal chronic vitamin deficiencies or anemia.
Example: MCV is like checking if red blood cells are too big or too small to do their job well.
How it’s measured: Blood test (part of CBC).
Mean Platelet Volume (MPV)
MPV measures the average size of your platelets, which helps in understanding blood clotting and platelet production health.
Example: MPV is like checking the size of sandbags in a flood—too big or too small affects how well they plug the leak.
How it’s measured: Blood test (part of CBC with platelets).
Platelet Count
This test counts how many platelets are in your blood. Platelets help with clotting and abnormal levels may suggest autoimmune disease, bone marrow disorders, or increased cardiovascular risk.
Example: Platelets are like emergency responders that plug leaks—too few or too many throws off the balance.
How it’s measured: Blood test (part of CBC).
Red Blood Cell (RBC) Count
This test counts the number of red blood cells you have. Abnormal levels can reveal anemia, chronic disease, or even bone marrow and heart conditions.
Example: RBCs are like your delivery fleet for oxygen—too few means low energy and health issues.
How it’s measured: Blood test (part of CBC).
Red Cell Distribution Width (RDW)
RDW measures the variation in red blood cell size. Along with MCV, it helps detect early nutrient deficiencies or liver disease.
Example: RDW is like checking if your delivery trucks (RBCs) are all the right size—too much variety = inefficiency.
How it’s measured: Blood test (part of CBC).
