Is WBC 3.61 low, normal or dangerous? What does White blood cell count level 3.61 mean?

📅 Medical Review Date: October 2, 2025

Your WBC level of 3.61 is a Low WBC level.

A WBC level of 3.61 thou/uL usually means the immune system is suppressed or the bone marrow is not producing enough white blood cells. It suggests leukopenia. Low levels of WBC can cause frequent infections, fever, chills, sore throat, mouth sores, and slow healing of wounds. This can be caused by bone marrow disorders, chemotherapy, radiation, autoimmune diseases, or severe viral infections. Further tests are often needed to identify the cause and guide appropriate treatment.

Low WBC levels may indicate underlying health problems. The normal range is typically between 4 thou/uL and 11 thou/uL. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal WBC range for men is :4 - 11 thou/uL

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

Some examples of conditions that increase or decrease WBC levels include:

• Infections, most commonly caused by bacteria and some viruses, less commonly by fungi or parasites
• Bone marrow damage
• Overwhelming infections (e.g., sepsis)
• Inflammation or inflammatory conditions such as vasculitis or inflammatory bowel disease
• Myelodysplastic syndrome
