Absolute neutrophil count or ANC is a measure of the number of neutrophil granulocytes present in the blood. Neutrophils are known as a type of fully developed white blood cells. These neutrophils play a vital role in the body’s ability to ward off infections and illnesses.
Normal white blood cell count range or WBC normal range is 4300-10,800 white blood cells per cubic millimeter of blood. Human bodies rely on neutrophils to effectively break down and make use of proteins for more efficient use. In this WBC normal range, neutrophils make up between 50 to 70 percent of the body’s total white blood cells. It is important to keep regular count of ANC for health reasons. If an unusually high absolute neutrophils count is present, this is a strong indication that there is threat to the body’s immune system and may need to be treated. Likewise, if there is a low count of ANC, then precaution has to be taken in order to prevent infections.
Advantages of ANC Calculation
As mentioned above, absolute neutrophil count gives a medical practitioner an indication of the body’s ability to fight diseases and infections. Part of the complete blood count takes into account neutrophils. Absolute neutrophil count is not measured directly. Instead, it is derived by multiplying the WBC count times the percentage of neutrophils present in the differential white blood count.
There are several advantages of ANC calculation. Given that neutrophils are vital in defending one’s self from infection, an absence or scarcity of neutrophils makes one vulnerable to infection.
Where risk of infection is high, then one should take precautions like staying away from crowds and so on. The calculation of ANC provides information on white blood count range. As such, medical practitioners will be able to tell if a patient has low WBC or high WBC. Information of the number of neutrophils will also be available through ANC calculation.
As such, if the neutrophil counts start to drop, then medical practitioners may advise patients to take special precautions when moving around so as to prevent catching any form of infection. For instance, such people may be advised to wash hands to limit the spread of infection or avoid crowded places which may be breeding grounds for infections. Those with very low ANC values may be hospitalized so that the safety of the patient is not compromised.
Alternatively, they may be asked to stay home and limit contact with others till the immune system is well again. ANC calculators are also advantageous in that they help doctors assess how well patients undergoing chemotherapy are responding to treatment. If the patient is seen not to be responding well to chemotherapy, then new treatment plans can then be devised so as to help the patient.
Neutrophils are pivotal in determining the wbc count range or white blood cell count range. These neutrophils absolute are also most crucial in responding to inflammation. Checking the absolute white blood cell count can help point to whether the infection is chronic or acute.The normal range for ANC is 1500 or higher.
A safe ANC value is considered to be between 500 and 1500. When compared to high wbc or high white blood cell count, a low ANC is less than 500. This means that the person’s condition is serious and immediate medical attention is required. Nonetheless, it is important to note that the values differ according to the type of machine used to conduct the blood test.
High ANC Count
High ANC count refers to an increase in leukocytes or cells responsible for fighting diseases circulating in your blood. An elevated white blood cell count can arise because of many reasons. Elevated WBC typically means that the body is trying to fight a possible infection. It could also mean that the body is reacting to a particular drug which is trying to improve the WBC count.
Diseases such as bone marrow disease could also be responsible in elevated WBC. Alternatively, it could also be because of an immune system disorder. However, the most common reason for elevated white blood cell count is infection. Additionally where the WBC is elevated for older people for extended periods of time in the absence of infections, it could indicate cancer of some sort.
