An Absolute Neutrophil Count (ANC) is a blood test that measures the number of neutrophils in your blood. Neutrophils are a type of white blood cell that helps your body fight infection. An ANC test may be ordered if you have signs of infection, such as fever, chills, or a cough. It may also be ordered if you are receiving chemotherapy or radiation therapy, as these treatments can lower your ANC.
The ANC is calculated by multiplying the total white blood cell count by the percentage of neutrophils in the blood. The normal ANC range is 1,500 to 8,000 cells per microliter of blood. An ANC below 1,500 cells per microliter is considered low, while an ANC above 8,000 cells per microliter is considered high.
To calculate the ANC, you will need to obtain the following information:
How to Calculate ANC
ANC is calculated using total WBC and neutrophil percentage.
- Obtain total WBC count.
- Get neutrophil percentage.
- Multiply WBC by neutrophil %.
- Normal range: 1,500-8,000.
- Low ANC: <1,500.
- High ANC: >8,000.
- ANC indicates infection risk.
- Monitor ANC during treatment.
ANC is an important indicator of your body's ability to fight infection. A low ANC can put you at risk for infection, while a high ANC may be a sign of an underlying medical condition.
Obtain total WBC count.
The total white blood cell (WBC) count is a measure of the number of white blood cells in your blood. White blood cells are part of your body's immune system and help to fight infection. A normal WBC count is between 4,500 and 11,000 cells per microliter of blood. A low WBC count can be a sign of infection, while a high WBC count may be a sign of inflammation or an underlying medical condition.
To obtain the total WBC count, a blood sample is collected and sent to a laboratory. The blood sample is then analyzed using a machine that counts the number of white blood cells in the sample. The total WBC count is reported as the number of cells per microliter of blood.
The total WBC count is one of the most common blood tests performed. It is often used to screen for infection, inflammation, and other medical conditions. The total WBC count can also be used to monitor the effectiveness of treatment for certain medical conditions.
If you have a low or high WBC count, your doctor may order additional tests to determine the cause of the abnormal WBC count. Treatment for a low or high WBC count will depend on the underlying cause.
The total WBC count is an important part of the ANC calculation. A low WBC count can lead to a low ANC, which can put you at risk for infection. A high WBC count can lead to a high ANC, which may be a sign of an underlying medical condition.
Get neutrophil percentage.
The neutrophil percentage is the percentage of neutrophils in the total white blood cell count. Neutrophils are a type of white blood cell that helps your body fight infection. A normal neutrophil percentage is between 40% and 70%. A low neutrophil percentage can be a sign of infection, while a high neutrophil percentage may be a sign of inflammation or an underlying medical condition.
To obtain the neutrophil percentage, a blood sample is collected and sent to a laboratory. The blood sample is then analyzed using a machine that separates the different types of white blood cells. The neutrophil percentage is reported as the percentage of neutrophils in the total white blood cell count.
The neutrophil percentage is one of the most common blood tests performed. It is often used to screen for infection, inflammation, and other medical conditions. The neutrophil percentage can also be used to monitor the effectiveness of treatment for certain medical conditions.
If you have a low or high neutrophil percentage, your doctor may order additional tests to determine the cause of the abnormal neutrophil percentage. Treatment for a low or high neutrophil percentage will depend on the underlying cause.
The neutrophil percentage is an important part of the ANC calculation. A low neutrophil percentage can lead to a low ANC, which can put you at risk for infection. A high neutrophil percentage can lead to a high ANC, which may be a sign of an underlying medical condition.
Multiply WBC by neutrophil %.
Once you have the total WBC count and the neutrophil percentage, you can calculate the ANC by multiplying the total WBC count by the neutrophil percentage. The ANC is reported as the number of neutrophils per microliter of blood.
For example, if the total WBC count is 7,000 cells per microliter and the neutrophil percentage is 60%, the ANC would be calculated as follows:
ANC = Total WBC count x Neutrophil percentage ANC = 7,000 cells/μL x 60% ANC = 4,200 cells/μL
A normal ANC is between 1,500 and 8,000 cells per microliter of blood. A low ANC can be a sign of infection, while a high ANC may be a sign of inflammation or an underlying medical condition.
The ANC is an important indicator of your body's ability to fight infection. A low ANC can put you at risk for infection, while a high ANC may be a sign of an underlying medical condition. If you have a low or high ANC, your doctor may order additional tests to determine the cause of the abnormal ANC. Treatment for a low or high ANC will depend on the underlying cause.
Multiplying the total WBC count by the neutrophil percentage is the final step in calculating the ANC. The ANC is an important indicator of your body's ability to fight infection. A low ANC can put you at risk for infection, while a high ANC may be a sign of an underlying medical condition.
Normal range: 1,500-8,000.
The normal ANC range is between 1,500 and 8,000 cells per microliter of blood. This means that a healthy adult should have between 1,500 and 8,000 neutrophils per microliter of blood.
An ANC below 1,500 cells per microliter is considered low, while an ANC above 8,000 cells per microliter is considered high. A low ANC can put you at risk for infection, while a high ANC may be a sign of inflammation or an underlying medical condition.
There are a number of factors that can affect the ANC, including:
- Infection
- Inflammation
- Certain medications
- Cancer
- Bone marrow disorders
If you have a low or high ANC, your doctor will order additional tests to determine the cause of the abnormal ANC. Treatment for a low or high ANC will depend on the underlying cause.
The normal ANC range is important to know because it can help you and your doctor determine if your ANC is too low or too high. A low ANC can put you at risk for infection, while a high ANC may be a sign of an underlying medical condition. If you have a low or high ANC, your doctor will order additional tests to determine the cause of the abnormal ANC and recommend the appropriate treatment.
Low ANC:
A low ANC, also known as neutropenia, is defined as an ANC below 1,500 cells per microliter of blood. Neutropenia can be caused by a number of factors, including:
- Infection
- Certain medications
- Cancer
- Bone marrow disorders
- Autoimmune diseases
- Nutritional deficiencies
Neutropenia can put you at risk for infection because neutrophils are an important part of your body's immune system. Neutrophils help to fight infection by engulfing and destroying bacteria and other harmful microorganisms.
Symptoms of neutropenia can include:
- Fever
- Chills
- Cough
- Shortness of breath
- Skin infections
- Mouth sores
- Diarrhea
- Fatigue
If you have a low ANC, your doctor will order additional tests to determine the cause of the neutropenia. Treatment for neutropenia will depend on the underlying cause.
A low ANC can be a serious medical condition, but it is important to remember that it is often treatable. If you have a low ANC, it is important to see your doctor right away so that the cause of the neutropenia can be determined and appropriate treatment can be started.
High ANC: >8,000.
A high ANC, also known as neutrophilia, is defined as an ANC above 8,000 cells per microliter of blood. Neutrophilia can be caused by a number of factors, including:
-
Infection
Neutrophilia is a common response to infection. When your body is fighting an infection, your bone marrow produces more neutrophils to help fight the infection.
-
Inflammation
Neutrophilia can also be caused by inflammation. Inflammation is a response to injury or tissue damage. When inflammation occurs, your body releases chemicals that stimulate the bone marrow to produce more neutrophils.
-
Certain medications
Some medications, such as corticosteroids, can cause neutrophilia.
-
Cancer
Some types of cancer, such as leukemia, can cause neutrophilia.
Neutrophilia can be a sign of an underlying medical condition, but it is not always a cause for concern. If you have a high ANC, your doctor will order additional tests to determine the cause of the neutrophilia. Treatment for neutrophilia will depend on the underlying cause.
ANC indicates infection risk.
The ANC is an important indicator of your body's ability to fight infection. A low ANC can put you at risk for infection, while a high ANC may be a sign of an underlying medical condition that is increasing your risk of infection.
There are a number of factors that can increase your risk of infection if you have a low ANC, including:
- Recent chemotherapy or radiation therapy
- Bone marrow disorders
- Autoimmune diseases
- HIV/AIDS
- Diabetes
- Chronic kidney disease
- Liver disease
If you have a low ANC, your doctor may recommend taking antibiotics to prevent infection. You may also need to avoid contact with people who are sick and practice good hand hygiene to reduce your risk of infection.
A high ANC may also be a sign of an underlying medical condition that is increasing your risk of infection. For example, people with leukemia often have a high ANC. In these cases, the high ANC is a sign of the underlying cancer, not an infection.
If you have a high ANC, your doctor will order additional tests to determine the cause of the neutrophilia. Treatment for the underlying cause of the neutrophilia will help to reduce your risk of infection.
Monitor ANC during treatment.
If you are receiving treatment for a medical condition that can affect your ANC, such as chemotherapy or radiation therapy, your doctor will likely order regular ANC tests to monitor your ANC during treatment.
-
Monitor for low ANC
During treatment, your ANC may drop to a dangerously low level. This is especially common with chemotherapy, which can kill healthy cells, including neutrophils. If your ANC drops too low, you will be at increased risk for infection.
-
Monitor for high ANC
In some cases, treatment can cause your ANC to rise to a high level. This is more common with radiation therapy, which can stimulate the bone marrow to produce more neutrophils. A high ANC can be a sign of an underlying medical condition, such as leukemia.
-
Adjust treatment as needed
If your ANC drops too low or rises too high during treatment, your doctor may need to adjust your treatment plan. For example, your doctor may need to reduce the dose of your chemotherapy or radiation therapy, or they may need to give you antibiotics to prevent infection.
-
Prevent infection
If you have a low ANC, you can take steps to prevent infection, such as washing your hands frequently, avoiding contact with people who are sick, and practicing good oral hygiene.
Monitoring your ANC during treatment is important to ensure that your ANC stays within a safe range. If your ANC drops too low or rises too high, your doctor can take steps to adjust your treatment plan and prevent complications.
