High Neutrophil Count And Disease
In addition to infection, there are other causes of elevated neutrophils. They can increase as a side effect of some medications. Certain medical conditions, such as cancer, allergic reactions, autoimmune disorders, trauma, and heart attack, can cause an increase in the number of neutrophils.
In some of these situations, such as during a heart attack or after an injury, the neutrophils work to help reduce damage and to facilitate healing.
Autoimmune conditions may cause neutrophils or other white blood cells to be elevated as the body attacks its own tissue. This may contribute to the symptoms of autoimmune conditions, such as swelling, fever, and pain. But changes in the neutrophil count with autoimmune diseases are usually not significant enough or consistent enough to be used in diagnosis or disease monitoring.
Absolute Neutrophil Count Test
There are 5 types of white blood cells and one amongst these types are neutrophils which play an important role in the response of the immune system against free radicals and antigens. One sure way to know the number of neutrophils in the blood is the Absolute Neutrophil Count . Let us know what is absolute neutrophils blood test and why one needs this test?
What Are Neutrophils In A Blood Test
What are neutrophils in a blood test? Of all the several types of white blood cells, neutrophils are the most prevalent that combat infections. If your absolute neutrophil count is above or below a healthy range, it can be used to determine whether your body has adequate neutrophils.

Absolute Neutrophil Blood Test Low
An absolute neutrophil blood test that is low indicates neutropenia and this is the result of having too few neutrophils. However, 1 single blood test that shows a low count of neutrophils does not necessarily indicate one has neutropenia. The levels can differ each day when tested, so repeated tests may be needed.
Causes Of Low ANC Levels
There are n number of causes that lead to this situation. The cause may be destruction, lessened manufacturing, or unusual storing of neutrophils.
The other reasons include
- Infections such as chickenpox, Hepatitis A, Hepatitis B, Hepatitis C, HIV/AIDS, and so on
- Autoimmune diseases like Granulomatosis with polyangiitis, Lupus, and Rheumatoid arthritis
- Bone marrow disorders such as Aplastic anemia, Myelodysplastic syndromes, and Myelofibrosis
- Additional causes include Kostmanns syndrome, chronic idiopathic neutropenia, vitamin deficiencies, and spleen abnormalities.
What Are Neutrophils In A Blood Test An Overview
Neutrophils are one of the types of white blood cells. They make up 55 to 70% of your white blood cells and are the most prevalent type.
White blood cells come in three varieties: granulocytes, lymphocytes, and monocytes. A subset of granulocytes that also includes eosinophils and basophils is known as neutrophils.
The bone marrow in your body produces neutrophils. The life span of neutrophils is only a day or fewer. Therefore, your bone marrow continuously produces new ones.

What Are Common Conditions That Affect Neutrophils
The number of neutrophils in your body needs to remain in a specific range to keep your body functioning normally. If your neutrophil count is too high or too low, you could acquire a condition thats the result of your neutrophils being out of range.
These conditions are:
- Neutropenia: Neutropenia is a condition where your neutrophil count is too low, causing swelling and repeated infections. Causes of neutropenia include cancer treatment, an autoimmune disease or an infection.
- Neutrophilia: Neutrophilia, also known as neutrophilic leukocytosis, occurs when your neutrophil count is too high, which is often the result of a bacterial infection. To combat the infection, immature neutrophils leave your bone marrow too soon and enter into your bloodstream.
What Does It Mean When Neutrophils Are High
An elevated number of neutrophils is most commonly a sign of a recent or ongoing infection. Typically, in these instances, neutrophils will be elevated for a short period of time as the body fights an infection, and then the neutrophils will eventually decrease to a normal level.
A higher than usual percentage of band neutrophils compared to segmented neutrophils in a blood count may be seen with an acute infection or acute inflammation as the bone marrow responds by releasing neutrophils earlier in their maturation process.
Having a high neutrophil count due to a resolving infection is not a cause for concern. It is a sign that the bodys immune system is effectively working to protect the body from infectious organisms.

Tumour Marker Blood Tests
Tumour markers are substances that might be raised if there is a cancer. Theyre usually proteins. They can be found in the blood, urine or body tissues. You might also hear them called biomarkers or molecular markers.
Doctors might use tumour marker tests together with the results of other tests you have to:
- help diagnose a cancer
- monitor how well your cancer treatment is working
- check if the cancer has come back
Some tumour markers are only made by one type of cancer. Others can be made by several types. Some tumour markers are found in non cancerous conditions as well as cancer. And some cancers dont have any tumour markers.
For those cancers that may have raised tumour markers, you can find out more in the tests section for that cancer type.
What Abnormal Results Mean
Any infection or acute stress increases your number of white blood cells. High white blood cell counts may be due to inflammation, an immune response, or blood diseases such as leukemia.
It is important to realize that an abnormal increase in one type of white blood cell can cause a decrease in the percentage of other types of white blood cells.
An increased percentage of neutrophils may be due to:
- Acute infection
- Acute or chronic forms of leukemia
- Myeloproliferative diseases
A decreased percentage of neutrophils may be due to:
- Aplastic anemia
An increased percentage of lymphocytes may be due to:
- Infectious mononucleosis , or mono
- Lymphocytic leukemia
- Multiple myeloma
- Viral infection (such as
A decreased percentage of lymphocytes may be due to:
An increased percentage of monocytes may be due to:
- Chronic inflammatory disease
- Viral infection
An increased percentage of eosinophils may be due to:
- Addison disease
- Allergic reaction
An increased percentage of basophils may be due to:
- After splenectomy
- Collagen vascular disease
- Myeloproliferative diseases
A decreased percentage of basophils may be due to:
- Acute infection

What Are Common Tests To Check The Health Of My Neutrophils
Tests that check the health of your neutrophils include:
- Complete blood count : A complete blood count test examines the cells in a sample of your blood that reflects how many cells are in your body. A CBC assists in diagnosing medical conditions and can be a benchmark to evaluate your overall health.
- Absolute neutrophil count : An ANC determines how many neutrophil cells are in a sample of your blood.
- Bone marrow biopsy: A bone marrow biopsy verifies how many cells your body has, along with identifying where they grow. Your healthcare provider removes and examines a small sample of your bone marrow. Cell production begins in your bone marrow, so a biopsy determines if your body is producing a healthy amount of cells or if there are certain conditions present.
What Questions Should I Ask My Healthcare Provider
Neutrophilia happens when your body produces too many white blood cells. There are lots of reasons why neutrophilia happens. Some questions you might want to ask your healthcare provider so you understand why you have neutrophilia include:
- How do you know I have neutrophilia?
- Whats my white blood cell count and whats a normal white blood cell count range?
- I dont feel sick. Why is my white blood count so high?
- Does having neutrophilia mean I have cancer or will develop cancer?
A note from Cleveland Clinic
Neutrophilia happens when your body produces too many neutrophils, a type of white blood cell that fights off infections. You may find out you have neutrophilia after routine blood tests or blood tests to learn why youre not feeling well. Either way, a larger-than-normal neutrophil count is your bodys reaction to changes. If blood tests show your neutrophil count is higher than it should be, your healthcare provider may do additional tests to find out why so they can treat the underlying condition.

What To Expect From The Anc Blood Test
A tiny amount of blood will be collected for the ANC test, typically from an arm vein. This will take place at a lab or at your doctors office. Your doctor will be informed of the results when the blood is examined in a laboratory.
NOTE: Your blood test results may be impacted by specific situations. Tell your doctor right away if youre expecting or if youve experienced any of the following:
- Chemotherapy or radiotherapy

How To Raise And Lower Levels
Nutritional yeast is a plant-based source of vitamin B-12.
The best way to correct abnormal neutrophil levels is to address and treat the underlying cause.
Antibiotics can treat bacterial infections, while antifungal medicine treats fungal infections. People can treat certain viral infections with medications that slow viral activity. Otherwise, supportive therapies, such as fluids and rest, may be part of the treatment plan.
People with altered neutrophil levels caused by medications or procedures may need to stop or adjust treatments. People with chronic conditions that disrupt adequate neutrophil production or maturation may need to take drugs that allow the body to raise neutrophil production, such as:
- colony-stimulating factors
- anti-thymocyte globulin
- bone marrow or stem cell transplantation
People with severely low levels of neutrophils often require monitoring, antibiotic therapy, and hospitalization to reduce the risk of severe infection. This period of intensive care helps keep people with weakened immune systems away from potentially harmful microorganisms. It also supports the body, giving it time to produce more white blood cells.
One of the causes of low neutrophil blood levels is a vitamin B-12 deficiency. Eating foods rich in B-12 may help improve low neutrophil blood levels. Examples of foods rich in vitamin B-12 include:
- milk and other dairy products
- many fortified breakfast cereals and bread products
- fortified nutritional yeast products

Where Do Neutrophils Come From
Neutrophils and all blood cells develop in the bone marrow. Immature neutrophils mature in the bone marrow for about 14 days and then circulate in the blood. In the bone marrow, they appear as juvenile neutrophils with a round nucleus. They also develop granules in their cytoplasm.
As they mature, the nucleus transforms from round to band-shaped, and they are called band neutrophils. A fully mature neutrophil has a segmented nucleus and is called a segmented neutrophil.
Both band and segmented neutrophils may be seen circulating in the blood. A small number of mature neutrophils also reside in some other tissues and organs throughout the body.
Neutrophils have a life span in the bloodstream of approximately one day. They migrate into tissues where needed and still have a short remaining lifespan. The body is constantly making new neutrophils, which replace the older neutrophils.
What Can Cause A High Neutrophil Count
A high neutrophil count is called neutrophilia or neutrophilic leukocytosis. It can be caused by a lot of different conditions, including:
Infection. This is the most common cause of a high neutrophil count. Most bacterial infections cause a high neutrophil count but not all of them do. Viral infections don’t generally cause neutrophilia but they may in the early stage of infection. Some fungal and parasitic infections can cause neutrophilia as well.
Inflammation. Any condition that causes inflammation in your body can increase your neutrophil count. Examples of this include:
- Rheumatoid arthritis and gout, which are types of arthritis
- Ulcerative colitis, which is irritation and ulcers in your large intestine
- Tissue damage from burns, surgery, or trauma
- Sickle cell crisis, which is a type of red blood cell disorder
- Acute kidney failure
- Diabetic ketoacidosis, a serious complication of diabetes when acids build up in your blood
- Cushing’s syndrome, which is when your body has too much cortisol
- Pre-eclampsia and eclampsia, which are complications of pregnancy that can cause organ damage
Some types of cancer. Cancers that can cause neutrophilia include:

How Long Will I Have Neutropenia
This will depend on the cause of the neutropenia. Although some causes of neutropenia will not get better, most causes of neutropenia get better over a couple of months or sometimes years. Other causes of neutropenia take many years to get better.

The information presented in this fact sheet is intended as a general guide only. Patients should seek further advice and information about Neutropenia and or their individual condition from their treating haematologist or doctor.
How Is Neutropenia Treated
Treatment for neutropenia depends on its cause and how severe it is. Not all cases need treatment.
Doctors use the ANC to help them make decisions about treatment. The ANC is a blood test that measures the number of neutrophils. The lower the number is, the more likely the child is to get serious infections.
Treatment, when needed, can include:
- correcting the neutropenia through:
- injections of granulocyte colony-stimulating growth factor to push the bone marrow to make more neutrophils
- steroid medicines to stop the body’s immune system from attacking the neutrophils
- white blood cell transfusions to give the child more infection-fighting cells
- stem cell transplant to replace the blood-forming stem cells with healthy donated stem cells
- surgical removal of the spleen since the spleen can sometimes destroy neutrophils
- preventing and treating infections with antibiotics

What Are Common Treatments For Neutrophil Conditions
Common treatments for low and high neutrophil counts include:
- Taking antibiotics.
- Getting a bone marrow transplant.
- Changing or stopping medication that causes neutropenia.
- Taking corticosteroids if you have an autoimmune disorder.
- Treating underlying medical conditions that affect your neutrophil count.
- Getting a white blood cell transfusion.
Why Do I Have Low Neutrophils
There are a number of reasons why people have low neutrophils. Some people are born with low neutrophils, other people develop conditions that cause low neutrophils these include immune problems, exposure to some drugs and some viral infections . There are a number of other rare causes of neutropenia.

Diagnosis Of Neutrophilic Leukocytosis
Doctors often do a blood test called a complete blood count. This test may be done for many different symptoms, including signs of infection , or signs of chronic illness .
If doctors discover an increased number of neutrophils and there is no clear reason, such as an obvious infection, a blood sample is viewed under a microscope to determine if immature neutrophils are leaving the bone marrow and entering the blood. Immature neutrophils in the blood may indicate the presence of a disorder in the bone marrow, such as leukemia.
What If Cbc Shows Aberrant Neutrophil Count
Additional evaluation is performed if your CBC doesnt show normal ranges for neutrophils. For that, your doctor will first conduct a history and physical exam, keeping in mind any probable causes of high levels.
The following procedure is frequently a peripheral smear , which can check for any other obvious abnormalities in the blood cells, including the neutrophils .
Depending on the potential reasons for an anomaly, additional testing can involve:
- Bone marrow biopsy to assess the cells in the bone marrow where they originated
- Examinations to look for infections
- Blood tests, including basic thyroid profile and vitamin B12 test

What Do The Results Mean
If your results were negative, it means your symptoms are probably not due to autoimmune vasculitis.
If your results were positive, it may mean you have autoimmune vasculitis. It can also show if cANCAs or pANCAs were found. This can help determine which type of vasculitis you have.
No matter which type of antibodies were found, you may need an additional test, known as biopsy, to confirm the diagnosis. A biopsy is a procedure that removes a small sample of tissue or cells for testing. Your health care provider may also order more tests to measure the amount of ANCA in your blood.
If you are currently being treated for autoimmune vasculitis, your results may show whether your treatment is working.
If you have questions about your results, talk to your health care provider.
Learn more about laboratory tests, reference ranges, and understanding results.
Understanding Your Lab Test Results
When you have cancer, you will probably need lab, imaging, or other tests. These tests are done to help watch your bodys response to treatment. They can show small changes before problems get serious. Keeping track of your lab results lets your doctor take action as soon as your blood counts change to help prevent many cancer-related problems and cancer treatment side effects.
Some people find it helps to ask for a copy of their lab results and have a member of their cancer care team go over the numbers with them. By getting a copy, you can also see what the normal ranges are for the lab that tested your blood and where your numbers fall within that range.
The Office of the National Coordinator for Health Information Technology enacted the Cures Act. The Cures Act is intended to make it easier for people to be able to see their medical records, clinical notes, and their costs of care. But, it doesn’t always allow health care providers to delay the release of health information to patients, including lab, imaging, pathology, and other test results. This means that patients may see their results on a patient portal at the same time as their health care provider or before their health care provider has had a chance to review and explain them.
Abnormal or unclear test results can make patients worry, especially if they have been waiting to see them. Talking to the health care provider who is ordering the tests ahead of time might help you might want to ask them:
