A high hemoglobin or hematocrit result on a blood test does not automatically mean a serious blood disorder. Trends, hydration and symptoms matter.
What should you know?
Dehydration may concentrate the blood. Smoking, high altitude, low oxygen related to lung or sleep disorders, and less commonly increased blood-cell production are other possibilities.
Practical steps
- Compare the result with previous complete blood counts.
- Tell your clinician about smoking, snoring, breathlessness, medication and hydration.
- Let a professional decide whether oxygen checks or further blood tests are needed.
When to seek professional assessment
Sudden chest pain, severe breathlessness or one-sided weakness require emergency assessment. Persistent elevations warrant medical review.
Frequently asked question
Does high hemoglobin always mean polycythemia?
No. Temporary concentration and secondary causes must be considered first.
