What is considered very high WBC?
In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.
Why would WBC be low or high?
Infection: Viruses can affect your bone marrow and cause low WBCs for a while. Severe infections, like blood infections, can lead to your body using up WBCs faster than it can make them. HIV kills a specific kind of white blood cell. Medicines: Some drugs, including antibiotics, can destroy WBCs.
What level of WBC indicates infection?
Normally the total WBC count for an adult ranges from 5,000 to 10,000/mm 3. Leukocytosis (WBC > 10,000/mm 3) can indicate infection, inflammation (possibly from allergies), tissue damage or burns, dehydration, thyroid storm, leukemia, stress, or steroid use.
What causes a low WBC in a blood test?
A low white blood cell count usually is caused by viral infections, congenital disorders, cancer or other diseases that damage bone marrow; drugs that destroy white blood cells or damage bone marrow; allergies, anemia, HIV/AIDS, leukemia, lupus, parasitic diseases, radiation therapy, Rheumatoid arthritis and vitamin deficiencies.
What medications cause high WBC?
Drugs that may increase WBC counts include: Beta adrenergic agonists (for example, albuterol) Corticosteroids. Epinephrine. Granulocyte colony stimulating factor. Heparin. Lithium.
What does a low WBC blood test mean?
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. A low number is sometimes called leukopenia.
What is a normal WBC count?
This count is usually measured in microliters. The normal range of a WBC is usually bordering from 4,300 to 10,800 cells per cubic millimeter or cmm. Some diagnostics usually round this off to 5.0 to 10.0 x 109 cells per liter.
