It is possible the pain could localize to the left lower quadrant in people with situs inversus totalis.
Many people with situs inversus totalis are unaware of their unusual anatomy until they seek medical attention for an unrelated condition, such as a rib fracture or a bout of appendicitis.

Rovsing's sign

Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), is a sign of appendicitis.

Hamburger sign

The Hamburger sign is used in the diagnosis of appendicitis.

McBurney's point

McBurney's sign
Coughing causes point tenderness in this area (McBurney's point), historically called Dunphy's sign.
Deep tenderness at McBurney's point, known as McBurney's sign, is a sign of acute appendicitis.

Massouh sign

The Massouh sign is a clinical sign for acute localised appendicitis, named after the General Surgeon Farouk Massouh from Frimley Park Hospital in Surrey/United Kingdom.

Fecalith

fecolithStercolithappendicolith
The causative agents include bezoars, foreign bodies, trauma, intestinal worms, lymphadenitis and, most commonly, calcified fecal deposits that are known as appendicoliths or fecaliths.
It is also called appendicolith when it occurs in the appendix and is sometimes concomitant with appendicitis.

Blumberg sign

rebound tendernessBlumbergrebound
There is severe pain on sudden release of deep pressure in the lower abdomen (rebound tenderness).
Positive Blumberg sign or rebound tenderness is indicative of peritonitis which can occur in diseases like appendicitis, and may occur in ulcerative colitis with rebound tenderness in the right lower quadrant.

Lymphadenopathy

lymphadenitisenlarged lymph nodesswollen lymph nodes
The causative agents include bezoars, foreign bodies, trauma, intestinal worms, lymphadenitis and, most commonly, calcified fecal deposits that are known as appendicoliths or fecaliths.

Alvarado score

The Alvarado score and pediatric appendicitis score are useful but not definitive.
The Alvarado score is a clinical scoring system used in the diagnosis of appendicitis.

Ectopic pregnancy

ectopic pregnanciesectopictubal pregnancy
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.
Other causes of similar symptoms include: miscarriage, ovarian torsion, and acute appendicitis.

CT scan

computed tomographyCTCT scans
The two most common imaging tests used are an ultrasound and computed tomography (CT scan).
Shortening of the scanning time to around 1 second, eliminating the strict need for the subject to remain still or be sedated, is one of the main reasons for the large increase in the pediatric population (especially for the diagnosis of appendicitis).

Fever

This includes viral, bacterial and parasitic infections such as the common cold, urinary tract infections, meningitis, malaria and appendicitis among others.

Rosenstein's sign

Obturator sign

In the clinical context, it is performed when acute appendicitis is suspected.

Psoas sign

psoas
In particular, the right iliopsoas muscle lies under the appendix when the patient is supine, so a positive psoas sign on the right may suggest appendicitis.

Meckel's diverticulum

Meckel diverticulumMeckel's diverticulitisMeckel's diverticulum ulcer
Children: Gastroenteritis, mesenteric adenitis, Meckel's diverticulitis, intussusception, Henoch–Schönlein purpura, lobar pneumonia, urinary tract infection (abdominal pain in the absence of other symptoms can occur in children with UTI), new-onset Crohn's disease or ulcerative colitis, pancreatitis, and abdominal trauma from child abuse; distal intestinal obstruction syndrome in children with cystic fibrosis; typhlitis in children with leukemia.
Occasionally, Meckel's diverticulitis may present with all the features of acute appendicitis.

Neutrophilia

Diagnosis is based on a medical history (symptoms) and physical examination which can be supported by an elevation of neutrophilic white blood cells and imaging studies if needed.
Neutrophilia can also be caused by appendicitis and splenectomy.
