What does it mean when WBC is normal?

Normal Results

The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens. Talk to your provider about your test results.

Does sepsis show on CBC?

The CBC of a patient with sepsis is commonly characterized by lymphocytopenia, neutrophilia, eosinopenia, thrombocytopenia, increased RDW, and increased NLR (Figure 2). The importance of thrombocytopenia in patients with sepsis is emphasized by the inclusion of platelet count in the SOFA score.

What WBC should be concerning?

How many white blood cells (WBCs) someone has varies, but the normal range is usually between 4,000 and 11,000 per microliter of blood. A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should.

What vitamin deficiency causes low white blood cells?

Some vitamins and minerals like vitamin B12 and folate play a crucial role in WBC formation. Low levels of vitamin B6, copper, and zinc may also play a role in low WBC production. A blood test can identify whether these nutrients are low, as you should not take supplements of these nutrients if your levels are normal.

Can anxiety cause low white blood cell count?

Calabrese says. In addition, stress decreases the body's lymphocytes — the white blood cells that help fight off infection. The lower your lymphocyte level, the more at risk you are for viruses, including the common cold and cold sores.
