Does high wbc mean infection?

White Blood Cells (WBCs) are the superheroes of our immune system, ever vigilant and on the lookout for anything that could potentially harm us. But have you ever wondered what happens when their numbers go through the roof? Is it always a sign of an infection? Let’s dive in to find out!

The Basics

WBCs, or leukocytes if you want to get fancy about it, are produced in our bone marrow and circulate throughout our body via blood vessels. They come in different types including Neutrophils, Lymphocytes, Monocytes, Eosinophils and Basophils – each type with its unique set of powers.

A high number of WBCs is known as Leukocytosis. It can be caused by a variety of factors ranging from infections to stress.

Infections

The most common cause for Leukocytosis is an infection (no surprise there!). When a pathogen like bacteria or viruses enter our body, they trigger the immune system which starts producing more WBCs to fight off this foreign invader.

As we know that there are different types of WBCs present inside us which act as specialist soldiers responsible for safeguarding against specific invaders:

Neutrophilia: This type includes neutrophil cells which usually increase first within hours after infections caused by bacterial organisms such as pneumonia or endocarditis.

Lymphocytosis: These include lymphocyte cells that play an essential role during viral illnesses since they help produce antibodies aimed at killing viruses such as influenza virus or HIV.

Non-Infectious Causes Of High White Blood Cell Count

It’s not just infections that can lead to increased white blood cell counts; other factors might shift things into overdrive:

  • Medications & drugs like corticosteroids
  • Allergic reactions
  • Autoimmune disorders
  • Stress

Absolute vs Relative Leukocytosis

There are two types of leukocytosis: absolute and relative.

Relative: This is when the number of WBCs remains normal or low, but their ratio to other blood cells such as red blood cells or platelets changes.

Absolute: In contrast, it means that the total number of WBCs increases above normal levels. If both relative and absolute values increase at once, things start looking grim (cue dramatic music).

When Should You Be Concerned?

High WBC count by itself might not be an issue always because sometimes, our immune system goes into overdrive due to non-serious matters like stress-induced changes in body functions than infections that can easily regulate back after some lifestyle modifications. Conversely, other reasons warrant a call for immediate medical attention:

  • High fever
  • Shortness Of Breath
  • Unusual headaches
  • Rapid heart rate

If you notice any of these symptoms accompanying high white blood cell counts,

book an appointment with your health provider immediately.

How Is High White Blood Cell Count Diagnosed?

A complete blood count test (CBC) is used to detect high levels of white hairballs in our system; besides revealing RBC and Platelet counts.

If there’s no apparent cause for increased white cell counts on CBC reports conducted during routine checks up under controlled conditions within specific hour slots particuarly from early morning fasted venipuncture samples after strictly adhereing to ancillary instructions, A more thorough physical assessment may take place earlier before pursuing further testing options.

Other tests your doctor may recommend include:

  • Blood cultures
  • Urinalysis
  • Imaging studies e.g CT Scan

While treating infections associated with elevated-white-blood-cell count:
– Antibiotics—especially if there’s bacterial infection causing neutrophil stimulation.
– Anti-viral medications In case of viral infections.
– Medications may be needed to reduce inflammation levels.

Takeaways

High white blood cell counts don’t always indicate a severe infection, but if you notice accompanying symptons like fever or shortness of breath—take them seriously and book an appointment with your physician immediately. It’s important to remember that CBC reports have limitations when it comes to giving a Detailed diagnosis; hence other tests such as Xrays & Biopsy might be necessary for further exploration.

Stay Healthy!
