What Happens During A White Blood Cell In Stool Test

Understanding Your CBC Test Result | Simplified RBC, WBC & Platelet Counts

You will need to provide a sample of your stool. Your provider or your child’s provider will give you specific instructions on how to collect and send in your sample. Your instructions may include the following:

  • Put on a pair of rubber or latex gloves.
  • Collect and store the stool in a special container given to you by your health care provider or a lab. You may get a device or applicator to help you collect the sample.
  • Make sure no urine, toilet water, or toilet paper mixes in with the sample.
  • Seal and label the container.
  • Remove the gloves, and wash your hands.
  • Return the container to your health care provider or the lab by mail or in person.

Is Wbc Of 176 High

The specific number for high white blood cell count varies from one lab testing facility to another, but a general rule of thumb is that a count of more than 10,500 leukocytes in a microliter of blood in adults is generally considered to be high, while 4,500-10,500 is considered within the normal range.

What Is A Low White Blood Cell Count

A low white blood cell count is an unusually low number of one or more kinds of white blood cells.

  • A low white blood cell count puts you at increased risk of infection

  • Some infections can be life-threatening

  • A low white blood cell count can be a side effect of drugs, particularly chemotherapy drugs

  • Sometimes a low white blood cell count is caused by an infection or cancer

  • Doctors may do blood tests and bone marrow tests to see why your white blood cell count is low

  • Doctors may give you medicine to increase your white blood cells and antibiotics if you have a fever or other signs of infection

How To Find Normal Values

Each lab has its own range for what it considers normal values for complete blood counts and chemistry panel results. Whats normal for one lab might not quite be normal for another, so its important to know what your labs normal range is when looking at your results. Normal ranges for some tests also vary by age and gender. On most lab reports the normal ranges for each test and a notation telling you if yours is high or low are printed on the lab report, next to your test results.

Common terms and numbers you may see on a CBC report and what they mean are on this chart:


What Does The Test Measure


A WBC count measures the total number of WBCs contained in a sample of blood. WBC, also called leukocytes, are an important part of the immune system. Made in the bone marrow, WBC help defend the body against infections and disease. There are five types of WBC, each supporting the immune system in a different way.

The WBC count is usually expressed as thousands of cells per microliter . Around 100 billion WBC are produced each day in the bone marrow. As they mature, WBC can be found in blood and the lymphatic system. There are five types of WBC:

A WBC count measures the total amount of all kinds of WBC. If a doctor needs information about the number of individual types of WBC, this information is provided in the WBC differential test.

How To Read Blood Test Results

While every laboratory or test-providing company may structure their result reports differently, they all must include the same components as mandated by federal legislation.

Some of that may be administrative content, such as the name of the person who did the blood test, the date the test was done, and the name of the doctor who ordered the test.

When it comes to understanding the results, you can look for the following :

  • Quantitative test result. Results will be typically written out numerically in cases when the test measured the quantity of something. For example, if the test measured the amount of cholesterol in your blood.
  • Abnormal markers. Often, a laboratory report will include some kind of marker to let you know if a result is outside the normal interval, and therefore abnormal. For example, you may see the letter H to indicate high, the letter L to indicate low, or the acronym WNL for within normal limits. You may see an asterisk and some additional comments in text if your results come out as highly abnormal. In this case, youll typically get a call from your doctor.
  • Reference range. Every laboratory will have its own reference range for each type of test. Typically, this reference range will be written in your laboratory report next to the numerical value of your result so you are able to see where your result falls in the range.

To a blood test, the nurse or technician:

  • Cleans the area on your arm where theyll draw the blood from.
  • What Affects The Test

    Reasons you may not be able to have the test or why the results may not be helpful include:

    • If the elastic band was on your arm a long time while the blood sample was taken.
    • Taking medicines that can cause low platelet levels. Some examples of the many medicines that cause low platelet levels include steroids, some antibiotics, thiazide diuretics, chemotherapy medicines, quinidine, and meprobamate.
    • A very high white blood cell count or high levels of a type of fat . These can cause falsely high hemoglobin values.
    • Having an enlarged spleen, which may cause a low platelet count or a low white blood cell count. An enlarged spleen may be caused by certain types of cancer.
    • Pregnancy, which normally causes a low RBC value and less often a high WBC value.

    Emotional Or Physical Stress

    Emotional or physical stress can cause inflammatory responses in your body that can result in high WBC and high neutrophils.

    A study published in the journal Industrial Health found a relationship between elevated white blood cell levels and stress at work. A high neutrophil count was also connected to high levels of cholesterol and fatigue. The overall result was an increase in low-grade inflammation.13

    Other scientific studies have shown a connection between high leukocyte count and atherosclerosis a buildup of plaque in the arteries. Elevated WBC count can increase a persons risk of stroke and heart attack.14

    Some ways to reduce stress and look after the health of your heart is to enjoy a healthy diet and get plenty of exercise.

    White Blood Cell Count Test

    White Blood Cells – Understand what your blood test tells you

    A white blood cell count is a test that measures the number of white blood cells in your body. It may also be called a leukocyte test. This test is often included with a complete blood count , which is commonly used to screen for different conditions that may affect your overall health.

    The term white blood cell count is also used more generally to refer to the number of white blood cells in your body.

    There are several types of white blood cells, and your blood usually contains a percentage of each type. Sometimes, however, your white blood cell count can fall or rise out of the healthy range. This may be due to an underlying condition or infection.

    Keep reading to learn the normal white blood cell count range is and what high or low white blood cell counts may mean.

    Effect Of Low Wbc Count

    The presence of a low WBC count in your blood refers to a condition known as leukopenia. When the level of WBC falls below 4,500 cells/mcL, it is known as a low WBC count. The lower levels of WBC can be due to various causes or health conditions like

    • Medicines or radiations used for the treatment of cancer,
    • Bone marrow failure or deficiency,
    • Autoimmune disorder,
    • Reporting as per NABL ISO guidelines

    White blood cells are an important component of blood. They are required by the body in an appropriate amount to fight infections and generate an immune response against foreign substances. An elevated or decreased level of WBCs can be due to different factors and underlying disease. The fluctuations in the level of WBCs can also indicate the possibility of an infection or disease. Therefore, you must always be very particular about the level of WBCs in your blood report.

    When Should I Get A Wbc

    A WBC count is a standard component of a CBC. A doctor may order a CBC in many situations, including:

    • During a routine doctor visit or checkup
    • While you are getting medical treatment that can affect your immune system and blood cell counts
    • For ongoing monitoring of chronic health issues that can affect blood counts, including chronic bone marrow disease

    Your doctor may also order a CBC if you have certain symptoms, such as:

    • Excessive tiredness or weakness
    • Fever or other symptoms of infection
    • Unexpected bleeding or bruising
    • Signs of cancer

    A doctor or other health care provider can share additional information about whether a CBC may be appropriate for your situation and how a WBC count is used to understand your health.

    What To Expect From A Wbc Count

    A healthcare professional or lab technician needs to draw blood to check your WBC count.

    This blood sample is typically taken either from a vein in your arm or a vein on the back of your hand. It only takes a couple of minutes to draw your blood, and you may experience minor discomfort.

    The healthcare professional first cleans the site to kill any germs. Then, they will typically tie an elastic band around the upper section of your arm. This elastic band helps the blood fill your vein, making it easier for the blood to be drawn.

    They may then insert a needle into your arm or hand to collect the blood in an attached tube. After, they will remove the elastic band from around your arm and remove the needle. Finally, the technician may apply gauze or a bandage to the site to stop the bleeding.

    Theres typically a different technique for drawing blood from young children and infants. This may include first puncturing the skin with a lancet and then using a test strip or a small vial to collect the blood.

    A laboratory typically processes these results. You may receive your results online, over a phone call, or during a follow-up visit.

    Having your blood drawn is a simple procedure, and complications are rare.

    Rare complications of a blood test may include:

    • infection at the needle site
    • excessive bleeding

    Where Can I Get Blood Work Done

    Pin on Laboratory stuff

    There are different locations that offer laboratory services that include blood work. Most hospitals contain a laboratory that you can visit to get tests done. Some laboratories will have walk-in options. Others may require an appointment.

    Additional locations for blood testing may include:

    • Private laboratories. Hospitals may use private labs to offload some testing from their own laboratories, or in cases when a specialized test is needed. Often, health insurance plans will require you to use a specific laboratory that is in their network for the test to be covered.
    • Point-of care. This describes situations when you may need to get a blood test wherever you are receiving medical care. In routine scenarios, this typically

    Results may take anywhere from a few hours to a few days to become available. Heres an overview of how long some common tests may take:

    • complete blood count : 24 hours
    • basic metabolic panel: 24 hours
    • complete metabolic panel: 24 to 72 hours
    • lipid panel: 24 hours

    Timing can depend on the specific lab where you get tested, and how many tests you get done at once. If you order multiple tests, you may not get the complete results until all of the tests are completed.

    Sometimes a lab will only release results to your doctor, who reviews them and then releases them to you.

    What Are The Causes Of Elevated White Blood Cell Count

    InfectionAs 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.

    Smoking or Chronic Obstructive Pulmonary Disease Essentially, COPD means that you have a lung and airway disease like emphysema or chronic bronchitis that blocks proper airflow. It is commonly caused by cigarette smoking, which results in inflammation in the lungs and air passages. As you gain more inflammation in your lungs and airways, your body will produce more white blood cells to fight it off.

    LeukemiaLeukemia is a type of cancer that dramatically increases your number of white blood cells. Leukemic white blood cells are often non-functional, which may increase the risk of infection in these cancer patients.

    Immune system disordersSome auto-immune disorders like Crohns or Graves disease can elevate your white blood cell levels. If you have one of these conditions, your doctor should monitor your white blood cell levels.

    StressFinally, emotional or physical stress can also cause elevated white blood cell counts. The good news is that white blood cell levels will return to normal after the stress is gone.

    Normal Reference Range Of Values

    No hard-and-fast number defines what a “normal” WBC count is. Instead, the results are reported in relation to the normal expected range of values within a population. Anything below this range is low, and anything above this range is considered high.

    A low or high WBC count doesn’t mean the same for all people, mainly if the values are borderline. This is because a “normal” WBC count can vary from one person to the next based on age, sex, race, smoking status, and other factors. WBC counts can also fluctuate throughout the day.

    Labs can also differ in defining a high or a low WBC count. So, it is possible to have a normal WBC at one lab and find that you have a low or high WBC count at another.

    WBC counts are measured by the number of white blood cells per cubic millimeter of blood . Here is an example of how a lab might define the expected range of values for a WBC count:

    What Are Common Tests To Check The Number Of White Blood Cells

    A complete blood count test identifies information about the cells in your blood. A lab completes this test after a medical professional draws your blood and examines your white and red blood cell count.

    White blood cells scan is a test to detect infection or abscesses in your bodyâs soft tissues. This test involves withdrawing your blood, separating the white blood cells from the sample, tagging them with a radioactive isotope, returning those white blood cells back into your body, then an imaging test will identify areas that show infection or abscess on your body.

    How To Increase Wbc Levels Naturally

    White Blood Cells are responsible for multiple body functions. So, maintaining healthy levels in the body is necessary, above anything else. If your WBC levels are chronically less, lifestyle and dietary changes can help proactively.

    Following are some ways how to increase WBC count naturally in the blood.

    What Are White Blood Cells

    White blood cells, also called leucocytes, detect and deal with infections or foreign molecules that enter your body. White blood cells will produce antibodies to fight the infection and help with other immune responses.

    They are one of four main components of your blood, along with red blood cells, platelets and plasma.

    White Blood Cell Count: What You Need To Know

    White blood cells, also known as leukocytes, help protect the body against infections, bacteria, viruses and diseases. These essential part of the immune system are produced in the bone marrow and are present in the blood and lymph tissue. White blood cells come in different types, and the blood normally contains a certain percentage for each type. This is what doctors check when they request tests that measure a persons WBC count.

    What Is The Normal Wbc Count

    Importance of white blood cell count By OpenStax

    The average WBC count in the blood generally ranges between 4,000 and 11,000/microliters. However, this is a standard range. The levels will vary for men, women, and children.

    The optimal WBC count in the blood indicates a healthy and fully-functioning immune system.

    In thefollowing chart, we will discuss the WBC normal range in females, WBC normal range in males and the WBC normal range in children.
