Hello,

Thank you for your question. Hope my answer will help you well.

According to your information about your CBC result of WBC down to 3.4 that have been confirmed from two separate readings.
Should you be concerned? A white blood cell (WBC) count of 3.4 is slightly below the typical normal range 4.0-12.0x10^3/ul. While this might not indicate a serious problem. But you need to determine the cause and whether any further testing or monitoring with your health provider. Good medical history and examination is very important to determine your cause.
You can increase WBC: first determine the underlying cause. Diet: by eating a diet that is rich in fruits, vegetables, proteins, and whole grains can support immune health. Exercise : regular, can maintain a healthy immune system. Sleep can ensure you get adequate and quality sleep. Manage stress if you have one.
If you are going to a gathering with many people, the supplements that you can take are Vitamin C the dose 500-1000 mg per day, Vitamine D the dose 1000-2000 IU per day, Zinc 15-30mg per day.
4. Drug that can increase WBC or immune fighting capability without much side effect. This question is difficult to answer for you. Because some drugs are used only for specific conditions such as for patients who have chemotherapy. You better do it naturally, as mentioned above, a healthy lifestyle we prefer you to follow because that is the best for no side effects.
Discussing with your home practitioner is better for your health.

Specialties to consult for low WBC
You can start with your primary care doctor, who can help you with initial evaluations. You better do it naturally as I mentioned the last answer, a healthy lifestyle we prefer you to follow and combination supplements.
2-3. Vitamin C supplementation: Daily intake of 500 to 1000mg of vitamin C is generally sufficient for most people. For gathering or when you’re at higher risk of exposure to infections, taking a higher dose of Vitamin C(e.g., 1500 to 2000mg) temporarily can be beneficial. But you need to be aware of gastric acid pain. Using a vitamin package meant for airline travel which often includes vitamin C and other immune-support nutrients, can be a good strategy when you’re exposed to crowded places.
4. Daily high intake of vitamin C impact on WBC is limited evidence that directly increases WBC count. However, vitamin C supports immune function, which can help maintain healthy WBC levels indirectly.
5. The differential WBC count and other CBC components (WBC, Differential WBC count, Red blood cell count, Platelets) are important for a comprehensive understanding of immune health.

Your body does not store vitamin C, so it is important to get a regular intake to maintain adequate levels. While occasional supplementation is 1500 mg of vitamin C on Sundays is unlikely to cause harm for most people, it's important to consider the benefits of consistent intake throughout the week and to ensure you’re meeting your daily vitamin C needs through a balanced diet whenever possible.
