Tests for appendicitis include physical exams, lab tests, and imaging tests such as CT scans and ultrasounds. Medical history and symptoms are also important for diagnosis. Physical exams can reveal pain and tenderness, as well as signs such as guarding and rebound tenderness. Lab tests can measure white blood cell count and rule out other conditions, while imaging tests can confirm the diagnosis.
There are a variety of tests to diagnose appendicitis, a medical condition in which an individual has an inflamed appendix. Different types of appendicitis tests include physical exam, lab tests, and imaging tests. In addition to these appendicitis tests, disclosure of medical history or symptoms can also help with the diagnosis.
A physical exam can help evaluate the pain and tenderness associated with appendicitis. For example, when an individual has appendicitis, he or she will feel pain in the right lower abdomen. The doctor can apply pressure to this area, and upon the sudden release of the pressure, the patient will feel pain due to rebound tenderness.
Also, protection usually appears in an individual with appendicitis. The guard is the act of tightening the abdominal muscles due to pressure. This act is subconscious and may occur before or after the doctor has actually touched the area.
Other physical appendicitis tests that help evaluate pain include those that check the obturator sign, psoas sign, and Rovsing’s sign. These are various tests that, when performed, cause abdominal pain due to movement or pressure from another area of the body. The presence of these signs can be indicators of appendicitis.
A physical exam might also include a rectal exam which can reveal tenderness due to appendicitis. Also, a woman might have a pelvic exam to rule out any gynecological conditions as the cause of the abdominal pain. This is because some of these conditions can produce symptoms similar to appendicitis.
In addition to a physical exam, lab tests can also diagnose appendicitis. Examples of lab tests include blood and urine tests. A blood test measures the patient’s white blood cell count; a high count is an indicator of an infection. A urine test can determine whether the patient’s pain is not due to appendicitis, but rather a kidney stone or urinary tract infection.
Usually, a physical exam and lab tests can be enough to diagnose appendicitis, but imaging tests can help confirm the diagnosis. Examples of useful imaging tests include a computed tomography (CT) scan and an ultrasound. An x-ray might also be helpful, but it’s more helpful in ascertaining other causes of abdominal pain than diagnosing an inflamed appendix.
In addition to several appendicitis tests, your medical history can help your doctor with the diagnosis. Since there are many causes of abdominal pain, knowing a patient’s medical history helps the doctor rule out other possible medical conditions. Also, like the diagnosis of any other disease, symptoms, if any, also play a role in the diagnosis. The main symptoms associated with appendicitis include abdominal pain that moves from the navel to the lower right abdomen, becomes more acute over time and worsens with sudden movements.
