Neutrophils are the most common type of white blood cell, comprising about 50-70% of all white blood cells. They are phagocytic, meaning that they can ingest other cells, though they do not survive the act. Neutrophils are the first immune cells to arrive at a site of infection, through a process known as chemotaxis.
Though neutrophils are short lived, with a half-life of four to ten hours when not activated and immediate death upon ingesting a pathogen, they are plentiful and responsible for the bulk of an immune response. They are the main component of pus and responsible for its whitish color. Neutrophils are present in the bloodstream until signaled to a site of infection by chemical cues in the body. They are fast acting, arriving at the site of infection within an hour.
Before ingesting invasive bacteria, neutrophils can release a net of fibers called a neutrophil extracellular trap (NET), which serves to trap and kill microbes outside of the cell. When neutrophils ingest microbes, they release a number of proteins in primary, secondary, and tertiary granules that help kill the bacteria. They also release superoxide, which becomes converted into hypochlorous acid, which is theorized to play a part in killing microbes as well.
A deficiency of neutrophils is called neutropenia and may be congenital or acquired, for example in certain kinds of anemia and leukemia, or as a side effect of chemotherapy. Since neutrophils are such an important part of the immune response, a lowered neutrophil count results in a compromised immune system.
Neutrophils may also malfunction, causing more harm to the body than they prevent. In alpha 1-antitrypsin deficiency, for example, inflammation, part of a normal immune response, leads to tissue damage. In Familial Mediterranean fever, the immune response is also so acute and prolonged that it can lead to a number of dangerous complications.

I agree with asking a doctor but I can guarantee that I care about my health and my family's health much more than any doctor I have ever met. Thanks wise geek for getting me up to speed on complex terms so that I am not too intimidated to ask questions because of unfamiliar jargon. I feel the admonishment comment goes further to scare readers into trusting doctors having large case loads and normal problems than it does to encourage doing research. Let's remember the medical community used to endorse lobotomies. |

Thank you wiseGEEK for an informative article! To everyone asking about their neutrophil levels or what they should do, I have this advice: 1. If you have questions, ask your doctor. If your doctor won't answer your questions, keep searching until you find one who will. 2. The author of this site is not a doctor; she has a BA in the social sciences. However, that doesn't mean that the information isn't correct (it is). She's very good at research and has written a simple definition, for the layperson, on a complex topic. But no matter how well-researched and written this article is, it's not a substitute for advice from a certified medical specialist. 3. Aside from the author, everyone else is posting anonymously. Even if someone answered your question, why would you ever trust an answer from an anonymous source? 4. If you really want to trawl the internet, in lieu of asking a live medical professional, then at least consult a medical website, not a generalized research site like wiseGEEK. The internet is rife with misinformation and inaccuracy. If you're not a doctor, you shouldn't be diagnosing yourself in the first place, especially based on your interpretation of something you found online, which may or may not be true. Do some due diligence, to the best of your ability, to make sure that the site is a reputable, credible, and trustworthy source for information. Otherwise, you may be doing yourself more harm than good. 5. And then, after all that, ask a doctor! No disrespect to wiseGEEK; you rock! If you can't find out who is responsible for the content on a site, you can't trust it. It's as simple as that.

Reading posts like these makes me wonder why we went through all the legal troubles of creating things like HIPPA whereupon all medical records are not to be shared with anyone without the patient's consent or written approval barring court order. Why on earth are people sharing their medical data online? That's a good question. If you have gotten through your usual 15 or 30 minute visit with your doc and you haven't asked that question, I suggest you pull one of his office aids or nurse aside and get an explanation of your results in plain english. They are good at breaking the medical jargon down to understandable terms and often more approachable. I was a CMA for five doctors in a medical office and quite capable of answering all these questions and so are they. Trust me: keep your information to yourself and seek the nurse out when you need a question answered. This is not the format for it. |

#41: It kind of sounds like you might have iron deficiency. when your red blood cells, hemoglobin and hematocrit are all low, normally this is the deficiency. try eating some foods with iron in it and you might feel better. red blood cells are pretty much four chains of iron bound to a blood cell so when you are low, the chain is low too! hope this helps! |

If you've read the entries online, neutrophils are the good cells, they fight infection. My sister has AML, a kind of leukemia, and after chemo her neutrophils were down to zero. Before she can have her bone marrow transplant, she has to have at least a count of 500 neutrophils. If anyone has prolonged fever, bruises, extreme exhaustion, sores that don't seem to heal, constant infections, especially a fungal type, then get to a doctor ASAP. These can be signs of leukemia, and you need to at least get checked out. This is nice, but no one here can or should diagnose you. Better to go to a doctor and find out what exactly is wrong, and get proper treatment. Health is far too serious an issue to let go. I am praying for my sister every minute because this is a very bad thing. |

When it says "post questions/comments" that doesn't mean "diagnose my symptoms". If you read a dictionary entry about hallucinations would you write the author and ask them if you have Schizophrenia? Call your doctor or nurse for medical questions! And if your doctor says your tests are all normal and you don't feel well, consider that it might just be stress. They know how to interpret your blood test results. Stop looking for reasons to be sick. |
