Understanding Hematocrit (HCT)

Hematocrit (HCT) is a key biomarker in blood tests that percentage of blood volume occupied by red blood cells.

What is Hematocrit?

Percentage of blood volume occupied by red blood cells.

Normal Range

Low < 38.3 %
Normal 38.3 - 48.6 %
High > 48.6 %

The normal Hematocrit range is between 38.3 and 48.6 %.

High Hematocrit Levels (Above 48.6 %)

Causes of High Hematocrit

High hematocrit can be caused by dehydration, smoking, lung disease, or polycythemia vera. Ensuring proper hydration, avoiding tobacco, and treating underlying lung or heart conditions can help lower levels.

Health Effects of High Hematocrit

High hematocrit increases blood viscosity, raising the risk of clotting, stroke, and heart attack. It can also cause headaches, dizziness, and impaired circulation.

Low Hematocrit Levels (Below 38.3 %)

Causes of Low Hematocrit

Low hematocrit is often associated with anemia, blood loss, chronic kidney disease, or nutritional deficiencies. Consuming a diet rich in iron, folate, and vitamin B12, staying hydrated, and treating underlying conditions like kidney disease can help increase levels.

Health Effects of Low Hematocrit

Low hematocrit reduces oxygen transport in the blood, leading to chronic fatigue, dizziness, and shortness of breath. If left untreated, it may result in cardiovascular strain and decreased immune response.

Treatment and Management

For High Hematocrit

  • Medical evaluation to determine the underlying cause
  • Lifestyle modifications as recommended by your healthcare provider
  • Regular monitoring of Hematocrit levels
  • Follow-up testing as needed

For Low Hematocrit

  • Medical evaluation to identify the root cause
  • Appropriate supplementation if recommended
  • Dietary changes as advised
  • Regular monitoring and follow-up

When to See a Doctor

Consult your healthcare provider if:

  • Your Hematocrit levels are consistently outside the normal range
  • You experience symptoms associated with abnormal Hematocrit levels
  • You have risk factors for conditions affecting Hematocrit levels
  • You’re taking medications that may affect Hematocrit levels

Prevention

  • Regular health check-ups
  • Balanced diet
  • Regular exercise
  • Stress management
  • Adequate sleep
  • Avoiding known triggers
