Permans sign: In acute appendicitis palpation in the left iliac fossa may produce pain in the right iliac fossa. Blood and urine test
While there is no laboratory test specific for appendicitis, a complete blood count (CBC) is done to check for signs of infection. Although 70–90 percent of people with appendicitis may have an elevated white blood cell (WBC) count, there are many other abdominal and pelvic conditions that can cause the WBC count to be elevated. Due to its low sensitivity and specificity, on its own, WBC is not seen as a good indicator of appendicitis. The diagnostic performance of novel molecules such as Interleukin-6, calprotectin and NGAL has recently been studied  in pediatric appendicitis and has shown moderate utility. Also, Interleukin-6 has shown has shown a moderate ability to discriminate between complicated and uncomplicated appendicitis in children. A urinalysis generally does not show infection, but it is important for determining pregnancy status, especially the possibility of an ectopic pregnancy in women of childbearing age. The urinalysis is also important for ruling out a urinary tract infection as the cause of abdominal pain. The presence of more than 20 WBC per high-power field in the urine is more suggestive of a urinary tract disorder. Imaging
In children the clinical examination is important to determine which children with abdominal pain should receive immediate surgical consultation and which should receive diagnostic imaging.
In most cases, patients going in for surgery experience nausea or vomiting that require medication before surgery. Antibiotics, along with pain medication, may be administered before appendectomies. After surgery
Hospital lengths of stay typically range from a few hours to a few days but can be a few weeks if complications occur. The recovery process may vary depending on the severity of the condition: if the appendix had ruptured or not before surgery. Appendix surgery recovery is generally a lot faster if the appendix did not rupture. It is important that people undergoing surgery respect their doctors advice and limit their physical activity so the tissues can heal faster. Recovery after an appendectomy may not require diet changes or a lifestyle change. The length of hospital stays for appendicitis varies on the severity of the condition. A study from the United States found that in 2010, the average appendicitis hospital stay was 1.8 days. For stays where the persons appendix had ruptured, the average length of stay was 5.2 days.After surgery, the patient will be transferred to a postanesthesia care unit, so his or her vital signs can be closely monitored to detect anesthesia- or surgery-related complications. Pain medication may be administered if necessary. After patients are completely awake, they are moved to a hospital room to recover. Most individuals will be offered clear liquids the day after the surgery, then progress to a regular diet when the intestines start to function correctly.
