白血球數 WBC
White Blood Cells (WBC)
*White blood cells (WBC) are an essential component of the immune system, responsible for combating infections, eliminating foreign substances, and regulating immune responses. Variations in WBC count and types can indicate various health conditions and are commonly used to assess infections, inflammation, or blood disorders.
*Normal Range
Adults: 4,000–11,000 cells/μL (or 4.0–11.0 × 10³/μL)
WBC consists of several types, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each serving distinct functions.
*Causes of Increased WBC (Leukocytosis)
-Infections:
Bacterial, viral, or fungal infections.
-Inflammation:
Autoimmune diseases like rheumatoid arthritis.
-Stress or Injury:
Physical trauma, burns, or post-surgical recovery.
-Blood Disorders:
Leukemia or other bone marrow-related conditions.
-Other Factors:
Smoking, certain medications (e.g., corticosteroids), or pregnancy.
*Significance:
An elevated WBC count is typically a response to infection or inflammation. Persistently high levels may indicate blood or immune system disorders.
*Causes of Decreased WBC (Leukopenia)
-Viral Infections:
Dengue fever, measles, or influenza.
-Bone Marrow Suppression:
Due to chemotherapy, medications (e.g., immunosuppressants), or toxins.
-Autoimmune Disorders:
Conditions like lupus.
-Nutritional Deficiencies:
Deficiency in vitamin B12 or folate.
*Significance:
Low WBC counts suggest weakened immunity, increasing vulnerability to infections and requiring further investigation.
*How to Maintain Healthy WBC Levels
-Support Immune Health:
Eat a balanced diet rich in vitamins and minerals, especially vitamin B12 and folate.
Follow regular sleep patterns and avoid overexertion.
-Prevent Infections:
Practice good hygiene, such as frequent handwashing and staying up to date with vaccinations.
-Avoid Harmful Substances:
Reduce smoking and limit exposure to chemicals or radiation.
-Routine Checkups:
Regular blood tests are crucial for individuals at risk of infections or blood disorders.
*Conclusion
WBC is a critical indicator of immune health, with abnormalities potentially pointing to infections, inflammation, or hematological conditions. By adopting a healthy lifestyle, ensuring proper nutrition, and undergoing regular checkups, you can effectively maintain WBC levels within the normal range. If WBC counts are abnormal, seek medical advice for further evaluation and appropriate treatment.
