ANC, or Absolute Neutrophil Count, is a measure of the number of neutrophils in your blood. Neutrophils are a type of white blood cell that helps your body fight off infections. A low ANC can indicate that you are at an increased risk of infection.
There are a few different ways to calculate ANC. The most common method is to use the following formula:
ANC = (Total WBC Count) x (% Neutrophils)
How to Calculate ANC
To calculate ANC, follow these steps:
- Obtain total WBC count.
- Determine percentage of neutrophils.
- Multiply WBC count by neutrophil percentage.
- Report the result as ANC.
- Interpret ANC result.
- Monitor ANC over time.
- Consult a doctor if ANC is abnormal.
- Take steps to prevent infection.
A low ANC can be caused by a variety of factors, including infection, chemotherapy, and certain medications. A high ANC may be a sign of inflammation or leukemia.
Obtain total WBC count.
The first step in calculating ANC is to obtain the total white blood cell (WBC) count. This can be done with a complete blood count (CBC), which is a common blood test that measures the levels of different types of blood cells in your blood.
- Request a CBC from your doctor.
You can typically get a CBC done at your doctor's office or at a lab.
- Fast for 8-12 hours before the test.
This is not always necessary, but it may be required by some labs.
- Have your blood drawn.
A healthcare professional will draw a small amount of blood from your arm.
- Receive your CBC results.
Your doctor or lab will typically have your results within a few days.
The CBC results will include the total WBC count, as well as the percentages of different types of white blood cells, including neutrophils.
Determine percentage of neutrophils.
Once you have the total WBC count, the next step is to determine the percentage of neutrophils in your blood. This can also be found on the CBC results.
The percentage of neutrophils is typically reported as a percentage of the total WBC count. For example, if the total WBC count is 10,000 cells/μL and the percentage of neutrophils is 60%, then the ANC would be 6,000 cells/μL.
There are a few different ways to determine the percentage of neutrophils in your blood:
- Automated cell counter.
This is the most common method. The CBC machine will automatically count the number of neutrophils in your blood and calculate the percentage.
- Manual differential.
This is a more time-consuming method, but it can be more accurate than an automated cell counter. A lab technician will manually examine a blood smear under a microscope and count the number of different types of white blood cells, including neutrophils.
Once you have the percentage of neutrophils, you can calculate the ANC using the formula:
ANC = (Total WBC Count) x (% Neutrophils)
Multiply WBC count by neutrophil percentage.
Once you have the total WBC count and the percentage of neutrophils, you can multiply these two numbers together to calculate the ANC.
For example, if the total WBC count is 10,000 cells/μL and the percentage of neutrophils is 60%, then the ANC would be:
ANC = (10,000 cells/μL) x (60%) = 6,000 cells/μL
This means that there are 6,000 neutrophils per microliter of blood.
The ANC can also be calculated using the following formula:
ANC = (Total WBC Count) x (% Neutrophils / 100)
Using the same example as above, the ANC would be:
ANC = (10,000 cells/μL) x (60% / 100) = 6,000 cells/μL
This formula is equivalent to the first formula, but it may be easier to use for some people.
Report the result as ANC.
Once you have calculated the ANC, you should report the result to your doctor or healthcare provider. The ANC is typically reported in cells per microliter (cells/μL).
The normal range for ANC is typically between 1,500 and 8,000 cells/μL. However, the normal range may vary slightly depending on the laboratory that performs the test.
If your ANC is outside of the normal range, your doctor may order additional tests to determine the cause. A low ANC may be caused by a variety of factors, including infection, chemotherapy, and certain medications. A high ANC may be a sign of inflammation or leukemia.
It is important to note that the ANC is just one measure of your overall health. Your doctor will consider the ANC along with other factors, such as your symptoms and medical history, to make a diagnosis.
Here are some tips for reporting the ANC result:
- Include the units.
The ANC should be reported in cells per microliter (cells/μL).
- Specify the reference range.
The normal range for ANC is typically between 1,500 and 8,000 cells/μL. However, the normal range may vary slightly depending on the laboratory that performs the test.
- Provide context.
Your doctor will need to know why the ANC was ordered and what symptoms you are experiencing.
Interpret ANC result.
Once you have reported the ANC result to your doctor, they will interpret the result and discuss it with you. The ANC can be used to:
- Detect infection.
A low ANC may be a sign of infection. This is because neutrophils are a type of white blood cell that helps the body fight infection.
- Monitor chemotherapy.
Chemotherapy can lower the ANC. This is because chemotherapy drugs can kill neutrophils along with cancer cells.
- Diagnose certain medical conditions.
A low ANC may be a sign of certain medical conditions, such as leukemia and aplastic anemia.
- Monitor bone marrow function.
The ANC can be used to monitor the function of the bone marrow. The bone marrow is responsible for producing new blood cells, including neutrophils.
The ANC is just one measure of your overall health. Your doctor will consider the ANC along with other factors, such as your symptoms and medical history, to make a diagnosis.
Monitor ANC over time.
In some cases, your doctor may recommend monitoring your ANC over time. This may be necessary if you have a condition that can affect the ANC, such as leukemia, chemotherapy, or a bone marrow disorder.
Monitoring the ANC over time can help your doctor to:
- Detect changes in the ANC.
A sudden change in the ANC may be a sign of an infection or other medical condition.
- Monitor the effectiveness of treatment.
If you are being treated for a condition that can affect the ANC, your doctor may monitor the ANC to see how well the treatment is working.
- Make decisions about treatment.
The ANC can be used to help make decisions about treatment, such as when to start or stop chemotherapy.
The ANC can be monitored with a simple blood test. The blood test can be done at your doctor's office or at a lab.
Here are some tips for monitoring the ANC over time:
- Keep a record of your ANC results.
This will help you and your doctor to track changes in the ANC over time.
- Tell your doctor about any new symptoms you experience.
This is especially important if you have a condition that can affect the ANC.
- Follow your doctor's instructions for monitoring the ANC.
Your doctor may recommend that you have the ANC tested regularly, or only when you are experiencing symptoms.
Consult a doctor if ANC is abnormal.
If your ANC is abnormal, it is important to see a doctor right away. A low ANC may be a sign of infection or other medical condition. A high ANC may be a sign of inflammation or leukemia.
Your doctor will ask you about your symptoms and medical history. They will also perform a physical examination and may order some tests, such as a blood test or bone marrow biopsy.
Depending on the cause of the abnormal ANC, your doctor may recommend treatment. Treatment may include antibiotics for infection, chemotherapy for leukemia, or a bone marrow transplant for aplastic anemia.
Here are some tips for consulting a doctor if your ANC is abnormal:
- Make an appointment with your doctor as soon as possible.
It is important to see a doctor right away if your ANC is abnormal.
