Is low white blood count serious?
Autoimmune diseases that attack your white blood cells can also lead to a low WBC count.
Several different prescribed drugs, including chemotherapy, are known to decrease WBC production or destroy WBCs.
A low WBC count can be serious because it increases your risk of developing a potentially life-threatening infection..
Can Viral infections cause neutropenia?
Viral infections are a common cause of neutropenia, due either to bone marrow suppression or to peripheral destruction. The agents commonly implicated include Epstein-Barr virus, cytomegalovirus, hepatitis A and B viruses, parvovirus, Influenzavirus species, and measles.
When should I be worried about low white blood cells?
A truly low white blood cell count also puts you at higher risk for infections — typically bacterial infections. But viral infections also may be a concern. To help reduce your infection risk, your doctor may suggest you wear a face mask and avoid anyone with a cold or other illness.
Do neutrophils increase with viral infection?
In contrast to emergent highly pathogenic respiratory viruses, notable “mild” human respiratory viruses also involve increased neutrophils at the site of infection (e.g., hRSV). As expected, infection with these viruses is typically associated with the increase of neutrophil chemoattractant chemokines.
Can low white blood cells cause fatigue?
Red blood cells carry oxygen around the body. This condition may contribute to weakness, fatigue or shortness of breath. Leukopenia: A low white blood cell count. A decrease in the production of functional leukocytes (white blood cells) weakens the body’s immune defense, which may make you more prone to infections.
What is the most common reason for low white blood cell count?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.
How long does neutropenia last after viral infection?
If the patient is found to be neutropenic during viral infection or a short time after viral infection, complete blood count should be repeated 2–4 weeks later. Generally, neutropenia improves during this period and examination of bone marrow is not needed.
What are the symptoms of having low white blood cells?
When your white blood cell count is low you may NOT have the usual signs and symptoms when developing an infection such as:Redness.Swelling.Pus formation (at the site of an injury or incision)Cough.Sputum.Nasal drainage (from a sinus or respiratory infection)
Can stress cause your white blood count to be low?
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.
What viral infections cause low white blood cell count?
Viral infections: Acute viral infections, such as colds and influenza may lead to temporary leukopenia. In the short term, a viral infection may disrupt the production of white blood cells in a person’s bone marrow. Blood cell and bone marrow conditions: These can lead to leukopenia.
Do WBC go up with viral infection?
Infection—As infection-causing bacteria or viruses multiply in the blood, your bone marrow produces more white blood cells to fight off the infection. Infection can also lead to inflammation, which can in turn cause the number of white blood cells to increase.
What WBC count 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 blood test indicates viral infection?
Full blood count — a viral infection may raise or reduce the white cell count; atypical lymphocytes may be reported. C-reactive protein (CRP) — this is elevated but usually less than 50 in a viral infection (CRP is a marker of inflammation anywhere in the body and is not a specific test for viral infections)
Is 3.5 WBC too low?
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.
Does CBC show viral infection?
A CBC test usually includes: White blood cell (WBC, leukocyte) count. White blood cells protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it.
Should I worry about low neutrophils?
If your neutrophil count is low, the doctor may say you are neutropenic. For most people with cancer, having a low neutrophil count is the biggest risk factor for getting a serious infection. Ask your doctor if your cancer treatment will cause your neutrophil count to drop.
What happens if WBC count is low?
White blood cells are produced by your bone marrow to help your body fight infection. If you have fewer than normal white blood cells, you have a higher risk of getting an infection. When you have a low white blood cell count, your immune system isn’t working as well as it should.
How can I raise my white blood cells fast?
