Seeing a low white blood cell (WBC) count on your complete blood count (CBC) test results is scary. It’s normal to worry that you’re sick or can’t fight infections well.

But if you haven’t been sick or had any infections, you should learn if your low white blood cell count is normal for you.

Some people are healthy, but their white blood cell count is naturally lower than the standard lab number. In these cases, having low white blood cell numbers doesn’t mean you can’t fight infections. It just means your “normal” white blood cell level is lower than the average lab range.

To understand how this can happen, it’s important to first know what white blood cells are.

What Are White Blood Cells?

White blood cells help you fight infections, viruses, and bacteria. They also help remove dead cells, parasites, toxins, and cancer cells.

Your bone marrow (the soft tissue in your bones) makes white blood cells. These cells then go into your blood and move to your organs to protect your body.

Your body makes different types of white blood cells, including:

  • Neutrophils: These are the “first responders” that kill and break down bacteria and fungi
  • Basophils: These cells tell other white blood cells to fight allergens and parasites by causing allergic reactions like sneezing or coughing.
  • Eosinophils: These cells help fight parasites, allergic reactions, and cancer cells
  • Lymphocytes: Different types of these cells fight viral infections and kill cancer cells
  • Monocytes: These are your “cleanup crew” that get rid of damaged or dead cells

Neutrophils are the most common type of white blood cell and often the focus of low WBC counts.

What Could Cause a Low White Blood Cell Count in a Blood Test?

A CBC test counts the number of white blood cells in your blood draw and measures them per microliter of your blood. Many labs rate a white blood cell count between 4000 and 11,000 cells per microliter as “normal.” But this varies since different labs use different reference ranges.

If your test reports your white blood cell count is low, that means the number of white blood cells in your blood draw falls below the lab’s standard range. This is called leukopenia.

What is Leukopenia? (And What is Neutropenia?)

Leukopenia means you have a low number of white blood cells in your blood. This condition can be pathological (something caused by a disease or medical problem) or non-pathological (something not caused by a disease or medical problem).

Pathological causes for low white blood cell counts

  • Autoimmune diseases that can make an immune system attack its own white blood cells
  • A lack of a vitamin or mineral — like Vitamin B12, folate, or copper — that keeps your bone marrow from making new blood cells
  • A swollen spleen that traps and destroys white blood cells
  • Blood cancers like leukemia that keep bone marrow from making enough white blood cells
  • Bacterial or viral infections that destroy white blood cells or use them up faster than they can be replaced

Non-pathological causes for low white blood cell counts

  • Medications (like chemotherapy drugs) that lower white blood cell counts
  • Leukopenia can occur during pregnancy
  • Intense exercise that temporarily lowers white blood cell numbers
  • Normal variations in certain populations that have lower WBC counts than other groups

Neutropenia is a type of leukopenia. It means you have a low number of neutrophils in your blood. Since neutrophils are the biggest part of your white blood cell count, neutropenia is the most common reason for a low white blood cell count.

Having fewer white blood cells can make it easier to get infections, causing symptoms like:

  • High temperature
  • Sore throat
  • Mouth sores
  • Toothache
  • Skin rashes
  • Tiredness
  • Flu-like symptoms

If you get any of these symptoms, call your doctor or get emergency medical care right away.

But if you don’t have these symptoms, your white blood cell count may have a harmless reason.

Can Having a Low WBC Count in a CBC Test Be Normal?

Lab reference ranges for “normal” cell counts are based on 95% of the population. This means 5% of healthy people fall outside these numbers.

If you’re healthy but have a low white blood cell count, this could mean you have:

DANC (Aka. “Benign Ethnic Neutropenia”)

DANC — or Duffy-null Associated Neutrophil Count — is a normal, healthy genetic condition where a person has fewer neutrophils in their bloodstream.

People with DANC may have lower circulating neutrophil levels even though they maintain normal immune function. The total number of neutrophils is often normal, but since many of their neutrophils aren’t moving through their blood, they don’t show up in a blood test.

DANC comes from a natural adaptation to help people fight disease in places affected by malaria. DANC does not turn into leukemia or a bone marrow disorder and is a lifelong, stable pattern.

DANC appears among many people with African ancestry and is also seen in some Middle Eastern and Mediterranean populations. This makes DANC a common healthy state.

People with DANC have normal immune systems and are not at increased risk of infections. Most do not need treatment or restrictions. However, having a qualified clinician confirm the diagnosis is important.

(DANC was once called Benign Ethnic Neutropenia (BEN) but was renamed to focus on science, not race.)

CIN

CIN (Chronic Idiopathic Neutropenia) is when a person’s blood has a low number of neutrophil white blood cells. “Chronic” means CIN lasts at least 3 months and “Idiopathic” means the cause is unknown.

CIN’s exact cause is often unknown and may involve different factors. However, it’s not a form of cancer and is often considered harmless.

Most people with CIN don’t have problems with infections. Even if their neutrophil count is low, they still make enough white blood cells to stay healthy.

But if a person’s neutrophil count drops to a very low level, they could be at greater risk of infection. If this happens, they can get medication. This may be a G-CSF (Granulocyte Colony-Stimulating Factor), a man-made hormone that gets the bone marrow to make more neutrophils.

Pseudoneutropenia

Sometimes, a blood test shows a false low count of neutrophil white blood cells. This is called Pseudoneutropenia (“false low neutrophil count”).

This can happen if neutrophils temporarily shift out of circulation due to stress, exercise, or certain medications. Neutrophils can also get damaged during testing, affecting measurement.

If your low white blood cell count is because the blood test is wrong, you’re at no increased infection risk. Your doctor may need to repeat the test to confirm.

What Should You Do If You See a Low WBC in Your CBC Test?

If you get a low white blood cell count on your blood test, your doctor needs to rule out different causes. You can help by:

Getting Tested by Your Doctor

Doctors need to check for any one of several possible causes for your low white blood cell count. Every cause has its own test.

Many tests are non-invasive and don’t need surgery. Getting these first (and confirming the reason for your low WBC count) can help prevent the need for invasive procedures that go into your body (like bone marrow biopsies).

Your doctor may order:

  • Multiple CBC tests to see if your low white blood cell count is temporary or long-term
  • WBC differentials that look at your different white blood cells to learn which one(s) are low
  • Peripheral blood smears that check the shapes of your blood cells to see if they look healthy
  • A physical exam to see if you show signs of illness or infection
  • A review of your medication history to see if your medications could lower blood cell counts
  • Nutritional tests to check for vitamin or mineral shortages

If you’re healthy but your ethnic background matches people who commonly have DANC, then you may receive Duffy antigen phenotyping. This test checks to see if your red blood cells lack a certain protein that shows you have DANC. Since DANC is rare compared to other possible low WBC causes, this test usually comes last.

Asking Your Doctor Questions

Ask questions about your test results. Start with:

  1. Is my white blood cell count low enough to increase my infection risk?
  2. How does this result compare to my other blood tests?
  3. Are my other blood levels (red blood cells, platelets) normal?
  4. What happens if I take medications that lower neutrophils?

Anticipating Your Doctor’s Questions

Your doctor may also ask you questions about your symptoms and medical history. Be prepared to answer healthcare provider queries like:

  1. Are there any other symptoms, like bleeding, joint pain, or swelling?
  2. Do these symptoms happen on and off (episodically) or constantly?
  3. Did you have a complete blood count (CBC) test done before this one? Was there any dramatic shift in white blood cell counts or other results?

Following Healthy Practices

Infection precautions are usually only needed for people with very low neutrophil counts or patients getting treatments that weaken their immune system. Follow your doctor’s guidance — it’s possible you may need to change medications or eat foods with nutrients that help make more white blood cells.

Updating Your Medical Records

If you have a harmless condition like DANC, make sure it’s recorded in your permanent medical record. This prevents unnecessary repeat testing, avoids surgical delays, and makes sure you aren’t unfairly excluded from clinical drug trials.

Learning You Have a Low WBC Count

A low white blood cell result is frightening, but if you feel well, it could be your normal healthy baseline. By working with your doctor to rule out illness, you can gain peace of mind and learn how to manage your health — whether that means a simple diet change or a note in your medical file.

My Struggle with Debilitating Eye Floaters: How a Vitrectomy Got Rid of My Floaters

In 2010, I was 33 years old and building my writing career. Then I started seeing flashes of light — like fireworks in the corners of my eyes — whenever I turned my head. Worried, I made an appointment with my eye doctor and received a terrifying diagnosis.

Both my eyes were experiencing a Posterior Vitreous Detachment (PVD). The vitreous gel — the jelly-like substance in my eyeballs — was pulling away from my retina, causing the flashes. If the gel pulled too hard, it could create a retinal tear or detachment resulting in partial or complete blindness.

Fortunately, the vitreous gel pulled cleanly away from my retinas, leaving them intact. But there were consequences.

Condensed collagen fibers from the vitreous gel cast dark shadows on my retina, creating long, stringy “floaters” that filled my vision. A large, cobweb eye floater or “vitreous veil” hung over my left eye like a second eyelid. Every time I moved my eyes, the floaters would move, making them impossible to ignore.

Overnight, I went from waking up eager to start the day to refusing to get out of bed and face a world covered in cobwebs.

Writing became torture as I stared through stringy lines covering my computer screen. Driving terrified me whenever a floater blocked my vision. Even looking at the sky felt like squinting through a dirty window.

Specialists told me I’d stop seeing floaters once they settled. They said I’d “get used to” living with them.

It didn’t happen. I started wearing dark glasses and stopped going out except at night.

Finding the Best Eye Surgeon for Floaters: Dr. Jack Sipperley

Eventually, I found support from the Degenerative Vitreous Community (aka “Floater Talk”), an online forum for people suffering from eye floaters.

I learned my condition can happen to people who are nearsighted like me. The elongated shape of my eyeballs that caused my myopia also stretched my retina, making it thinner and more fragile. My vitreous gel was also prone to liquification, making it pull away from my retina and experience a PVD earlier than non-myopic people.

I also learned of a treatment called a vitrectomy, a surgical procedure where an eye surgeon makes incisions in the eyeball and removes the vitreous gel, replacing it with a saline solution. This physically removes the floaters, restoring clear sight to the eyes.

Today, vitrectomies for floaters are considered safer, thanks to narrower instruments that let surgeons make smaller, sutureless incisions, allowing for increased surgical effectiveness and fewer complications. But back in the 2010s, many surgeons I contacted reserved vitrectomies for severe cases due to risks like bleeding, infection, and retinal detachment.

Fortunately, Floater Talk told me of Dr. Jack Sipperley, MD, a highly experienced retina specialist who specializes in vitrectomies and provides care at Barnet Dulaney Perkins Eye Center, not far from where I live. Patients spoke highly of Dr. Sipperley and many flew great distances to be treated by him.

My Vitrectomy Recovery Timeline: When Did My Vision Get Clear?

My first consultation with Dr. Sipperley went well. He listened to my concerns and took scans of my eyes. I was surprised by how casual he was about performing a vitrectomy once tests determined it could help my condition.

He also explained the risks of the procedure — including the possibility of early cataract formation. Since I was already at risk for cataracts due to my nearsightedness, I was okay with this.

Surgery for my left eye was scheduled for September 13, 2012. I came to my appointment worried and nervous, but Dr. Sipperley’s professionalism (and the IV sedation) put me at ease.

I stayed in a state of semi-consciousness as Dr. Sipperley placed a local anesthetic block around my eye to numb the area and minimize movement. I could see the shadows of his instruments enter my eye, creating bright lights as gas bubbles and visual debris cast black spots against my retina.

None of this scared me. Instead, I felt elation as Sipperley removed the floaters and let me know my eye tissues were in good shape.

They placed a patch over my eye but briefly removed it post-surgery, letting me see a white wall that was free from eye floaters. I was ecstatic.

Recovery took weeks. My left eye was bloodshot and light sensitive, but this went away as I took prescription eye drops for preventing infection and inflammation. Most of the pain in my eye and face faded after the first night, but I did feel a twinge in my eyeball when I moved it and saw a small line on the outside corner of my left eye. These also gradually faded.

I couldn’t make sudden head movements as my eye healed. However, I didn’t have to sleep face-down like vitrectomy patients who get gas or oil bubbles inserted into their eyes to treat retinal detachments or macular holes.

After a few weeks, I could wear my contact lens and regain clear vision. The difference was astonishing. Even with floaters still in my right eye, the world looked cleaner and brighter. I could write, read, and drive with more confidence.

And the blue sky never looked better.

A Better Life After Vitrectomy: Getting Rid of Eye Floaters for Good

I got a vitrectomy for my right eye later, and the quality of my vision increased considerably. Since then, I’ve gone sightseeing in Germany, gazed at waterfalls in Hawaii, and enjoyed the view from the top of Mount Hood in Oregon.

I did get cataracts in my forties, but Barnett Dulaney successfully removed them and I now see better than ever.

Living with eye floaters for years has increased my appreciation for my sight. Every time I look up at the sky, I think how lucky I was to have found Dr. Sipperley, and encourage anyone suffering from eye floaters to look into a vitrectomy.
