A Hematocrit test measures the proportion of your blood volume that consists of red blood cells. It’s expressed as a percentage and is an important indicator of blood health.
What This Test Measures
Hematocrit (Hct):
The percentage of blood volume occupied by red blood cells. For example, a hematocrit of 45% means 45% of your blood volume is red blood cells and 55% is plasma and other components.
Reference Ranges
Adult Men: 38.3-48.6%
Adult Women: 35.5-44.9%
Ranges may vary slightly by laboratory and altitude (higher altitudes = higher normal ranges).
Who Should Consider This Test
• Those with symptoms of anemia (low hematocrit):
– Fatigue and weakness
– Pale skin
– Shortness of breath
– Dizziness
– Cold hands and feet
• Those with symptoms of polycythemia (high hematocrit):
– Headaches
– Dizziness
– Blurred vision
– Ruddy complexion
• Men on testosterone replacement therapy (TRT):
– Testosterone can increase red blood cell production
– Regular monitoring is essential to detect elevated hematocrit
– Levels above 52-54% may require intervention (blood donation, dose adjustment)
• Monitoring conditions affecting red blood cells
• Evaluation before surgery
• Living at high altitude
Why Hematocrit Matters for TRT
Testosterone stimulates erythropoietin production, which increases red blood cell production. This can raise hematocrit to unhealthy levels (polycythemia), increasing the risk of blood clots, stroke, and heart attack. Regular monitoring is essential for men on testosterone therapy.
