Exploring Neutrophils: Key Players in the Immune Response

The absolute neutrophil count (ANC) in the body makes it easy to determine how healthy your body is. The doctor may ask for an (ANC) test to know the status of many health-related problems.

• For information about many types of physical conditions.
• For the diagnosis of a disease.
• ANC is also asked for during chemotherapy.

If the ANC level remains abnormal during the test, the doctor may ask you to get a blood test done several times a week. By doing this, it becomes clear how the neutrophil count is changing in the body.

The normal amount of neutrophils in adults is 1,500-8,000 (1.5-8.0) neutrophils / microliter. In case of its deficiency, the scale can be 1,000-1,500 neutrophils/microliter and in very severe condition <500 neutrophils/microliter. At the same time, more than 8,000 neutrophils are considered to be increased levels. Let us know what is the main reason for the increase and decrease of neutrophils?

A decrease in the level of neutrophils is known as neutropenia. The intake of certain types of drugs can cause a decrease in the level of neutrophils, however, it can also be a sign of many types of diseases. The following conditions can also cause a decrease in neutrophils.

• Due to some other drugs including drugs used in chemotherapy.
• Any type of blockage in the immune system.
• Bone marrow failure
• Aplastic anemia
• Febrile neutropenia This is a medical emergency
• Hepatitis A, B, or C
• HIV/AIDS
• Sepsis
• Many autoimmune diseases including rheumatoid arthritis
• Leukemia
• Myelodysplastic syndrome

If the number of neutrophils in your body is less than 1,500 neutrophils per microliter, then you need to be very careful. In such a situation, the risk of infection increases a lot. Due to the level of neutrophils falling very low, fatal infection can occur, which can also lead to death.

The condition of abnormal increase in neutrophils in the blood is known as neutrophilic leukocytosis or neutrophilia. Usually, the level of neutrophils increases naturally due to infection or injury. The following types of conditions can also be the cause of neutrophilia.

• Certain types of medications
• Several types of cancer
• Emotional stress
• Surgery or accident
• Tobacco use
• Pregnancy
• Obesity
• Genetic conditions such as Down syndrome

Inflammatory conditions such as rheumatoid arthritis, inflammatory bowel disease, hepatitis, and vasculitis can also cause neutrophilia. Neutrophil counts above 8,000 are usually considered to be the most common neutrophil count.

Neutrophils are a type of white blood cell that is an important part of the body's immune system. They play a major role in the defense against infection and inflammation. When the body senses an infection, neutrophils rapidly travel to the affected area and attempt to destroy germs (such as bacteria and viruses). They kill germs by engulfing them and swallowing them through a process called phagocytosis. The average lifespan of neutrophils is about a few hours to a few days, and they are produced in the bone marrow. Their number increases in case of infection or inflammation in the body, which indicates that the body is fighting the infection.
