NC ratio
NC Ratio
The NC Ratio (pronounced as N-C Ratio) is a medical term that refers to the ratio of neutrophils to lymphocytes in the blood. This ratio is often used as a diagnostic tool in various medical conditions, particularly in the field of oncology.
Etymology
The term "NC Ratio" is an abbreviation of "Neutrophil to Lymphocyte Ratio". Neutrophils and lymphocytes are types of white blood cells, which are crucial components of the immune system. The term is derived from the Greek words "neutros" (meaning neutral) and "philos" (meaning loving), and "lymphocyte" is derived from the Greek words "lympho" (meaning clear, watery) and "cyte" (meaning cell).
Usage
The NC Ratio is often used as a prognostic factor in various types of cancer. A high NC Ratio may indicate a poor prognosis in patients with certain types of cancer, such as breast cancer, lung cancer, and colorectal cancer. It is also used in the diagnosis and monitoring of inflammatory and infectious diseases.
