ANC can refer to two different things:
-
Active Noise Control: ANC, also known as noise cancellation or active noise reduction, is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
-
Absolute Neutrophil Count: ANC is a measure of the number of neutrophils in the blood, which are a type of white blood cell that kills bacteria. It is used to estimate the bodys ability to fight infections, especially bacterial infections. The ANC is calculated by multiplying the number of white blood cells in blood by the percentage of total neutrophils.aspx).
In the medical context, ANC is often used to monitor patients undergoing chemotherapy, as chemotherapy can cause a decrease in the number of white blood cells, including neutrophils. If the ANC is too low, the doctor may decide to delay chemotherapy or take other precautions to prevent infections.
