A WBC in a blood test stands for white blood cell. White blood cells, also known as leukocytes, are a crucial part of your immune system. They are created in your bone marrow and are found in your blood and lymph tissue.
A white blood cell count is a blood test that measures the number of white blood cells in your blood. This test is often part of a complete blood count (CBC), which is a common screening tool for various health conditions.
A normal white blood cell count for adults ranges from 4,000 to 11,000 WBCs per microliter of blood. However, it's important to note that these ranges can vary depending on age, sex, and other factors.
A high WBC count can be a sign of infection, inflammation, or certain types of cancer.
A low WBC count, also known as leukopenia, can increase your risk of infection. It can be caused by various factors, including viral infections, certain medications, and bone marrow disorders.
