Hematocrit
Hematocrit is a critical performance metric that reflects your blood's oxygen-carrying efficiency. For athletes, tracking hematocrit levels helps optimise training load, monitor hydration status, and ensure your cardiovascular system supports peak athletic output.
What It Measures
This test measures the proportion of red blood cells relative to the total volume of blood. The result is expressed as a percentage and reflects both the number and size of red blood cells in your bloodstream.
Why It Matters
Hematocrit levels provide important information about your overall blood health. Low hematocrit may indicate anemia or fluid overload, while elevated levels can be associated with dehydration, chronic lung conditions, or blood disorders. Monitoring hematocrit helps detect these conditions early.
When to Test
Hematocrit is typically measured as part of a complete blood count (CBC) during routine health check-ups, when investigating symptoms of anemia or dehydration, or for monitoring chronic health conditions.
