20 markers in this category
Basophils
Basophils are the least common white blood cells and play a role in allergic and inflammatory responses, partly by releasing histamine. For active people, long-standing inflammation can affect recovery. A raised count is uncommon and is reviewed together with your other values.
Blood Type + Rh
A blood type test determines your ABO blood group and Rh factor. Knowing your blood type is essential for safe blood transfusions, organ transplants, and pregnancy planning.
Complete Blood Count (CBC)
The complete blood count is the ultimate performance baseline for active individuals. By tracking red blood cells, white blood cells, and platelets together, a CBC provides a holistic view of your oxygen delivery, immune resilience, and recovery capacity — all critical for training optimisation.
Coombs Test (Indirect)
The indirect Coombs test screens for unexpected antibodies in your blood that may react against red blood cells. It is an important test for transfusion safety and prenatal care.
Eosinophils
Eosinophils are white blood cells involved in allergic reactions and the defence against parasites. This can be relevant for active people, as allergies and asthma can affect breathing and training capacity. A raised count is often seen with allergies or asthma, while a low count is usually not a concern.
Erythrocytes (RBC)
Red blood cells are the oxygen highway for your muscles and tissues. For active individuals and active individuals, monitoring erythrocyte levels provides insight into your aerobic capacity and recovery potential, helping you train smarter and perform at your peak.
Haptoglobin
A haptoglobin test measures the level of haptoglobin protein in your blood. Haptoglobin binds to free hemoglobin released from damaged red blood cells, and its levels can help assess whether red blood cells are being destroyed faster than normal.
Hematocrit
Hematocrit is a critical performance metric that reflects your blood's oxygen-carrying efficiency. For active individuals, tracking hematocrit levels helps optimise training load, monitor hydration status, and ensure your cardiovascular system supports peak physical output.
Hemoglobin
Hemoglobin is your primary oxygen-delivery molecule and a cornerstone metric for endurance performance. Monitoring hemoglobin levels helps active individuals assess training adaptations, identify early signs of overtraining, and optimise recovery strategies.
Hemoglobin Electrophoresis
Hemoglobin electrophoresis is a laboratory technique that separates and identifies different types of hemoglobin in your blood. It is primarily used to detect hemoglobin variants and diagnose inherited blood disorders such as sickle cell disease and thalassemia.
Irregular Antibody Screening
An irregular antibody screening test detects unexpected antibodies in your blood that may react against foreign red blood cells. These antibodies can develop after transfusions, pregnancies, or immune stimulation and are important to identify for transfusion and pregnancy safety.
Leukocyte Differential
A leukocyte differential test measures the relative proportions of different types of white blood cells in your blood. It provides a detailed breakdown of your immune cell populations, offering valuable insight into your immune system's function.
Leukocytes (WBC)
A leukocyte (white blood cell) count measures the total number of white blood cells in your blood. White blood cells are a crucial part of your immune system, defending your body against infections, viruses, and other harmful invaders.
Lymphocytes
Lymphocytes are white blood cells central to your defence against viruses. This is relevant for active people, as intensive training and insufficient recovery can temporarily affect immune defence. A high count often fits a viral infection, while a low count can occur with stress or overload.
MCV (Mean Corpuscular Volume)
MCV (Mean Corpuscular Volume) measures the average size of your red blood cells. It is a key indicator used to classify different types of anemia and provides insight into the underlying cause of blood-related conditions.
Monocytes
Monocytes are the largest white blood cells and part of your complete blood count. They clear away damaged cells and pathogens and turn into macrophages that support tissue repair. For active people this matters, as a raised count can fit inflammation or recovery after an infection, while a low count is less common.
Neutrophils
Neutrophils are the most common white blood cells and your first defence against bacterial infections. This matters for active people, as heavy training load can temporarily affect immune defence. A high count often fits an infection, inflammation or physical stress, while a low count can leave you more vulnerable.
Platelets (Thrombocytes)
A platelet (thrombocyte) count measures the number of platelets in your blood. Platelets are small cell fragments essential for blood clotting, helping to stop bleeding when blood vessels are injured.
RDW
RDW shows how much your red blood cells vary in size. For active people this is valuable, because healthy red blood cells carry oxygen to your muscles. A raised RDW can be an early clue to a shortage of iron, vitamin B12 or folate, which may limit endurance and recovery.
Reticulocytes
Reticulocytes reveal how rapidly your body is producing fresh red blood cells — a key recovery metric for active individuals. Tracking reticulocyte counts helps you understand how your bone marrow responds to training stress, altitude exposure, and periodised recovery programmes.
