How to check for appendicitis? It turns out that these 4 tests can detect appendicitis

Appendicitis, also known as appendicitis, has the characteristics of a wide range of incidence and great harm to the human body. Therefore, as long as people have symptoms of appendicitis, they must go to the hospital for examination and diagnosis in time so as to receive timely treatment. So what tests are needed for appendicitis? In fact, you only need to do four tests: routine blood tests, routine urine and stool tests, serum tests, and puncture fluid tests.

1. Routine blood test . Total white blood cell count and neutrophilia in suppurative appendicitis Total white blood cell count may rise to (10-12)×109/l; in suppurative appendicitis it may be as high as (12-14)×109/l; when there is abscess formation or diffuse peritonitis, the white blood cell count may reach more than 20×109/l. Neutrophil count is 0.85-0.95 and has a left shift. If the neutrophil count increases to more than 0.85, it is a sign of severe disease, and sometimes toxic particles may be seen. However, in some children with appendicitis, the white blood cell count does not rise significantly.

2. Routine urine and stool examination. Generally there are no special changes. For example, when the appendix is ​​located near the ureter, there will be a small amount of red blood cells in the urine. When the condition is more serious, there may be a small amount of pus balls in the stool.

3. Serum . It has been reported that serum C-reactive protein and fibronectin values ​​are significantly increased and plasma fibronectin values ​​are decreased in children with acute appendicitis. These two measurements can be used as auxiliary indicators for judging the severity of appendicitis before surgery.

4.Puncture fluid examination. For patients with suspected appendicitis but difficult to diagnose, especially those with symptoms of peritonitis, abdominal puncture can be tried. Generally, a subcutaneous needle is used to puncture the appendix in the right lower abdomen, and the puncture fluid is examined by microscopic bacterial smear and biochemical examination. Those with pus balls in microscopic examination are mostly early suppurative appendicitis; if the puncture fluid is thin, it is mostly early localized peritonitis; if the puncture fluid is pus-rich and sticky, or bloody, with a fecal odor, and those with a large number of bacteria in the smear are mostly gangrenous appendicitis, diffuse peritonitis or periappendiceal abscess.
