Diagnostic difficulties for one of the most common cause for ED visits

Acute abdominal pain (AAP) accounts for about 10 % of all Emergency Department (ED) visits worldwide. In the US and Europe combined, more than 23 million patients visits the ED due to acute abdominal pain.

1/4 misdiagnosed

Even in experienced hands, the manual palpation of patients leads to misdiagnosis in one forth of patients with abdominal pain.

1/3 Exposed to radiation

This leads to that more than one third of patients in the ER with abdominal pain is exposed to radiation. X-ray is expensive and time-consuming and increases the risk of developing cancer.

1/4 Unnecessary CT scans

Inexperience leads to overutilization of imaging techniques, and it is estimated that up to 25 % of all X-ray investigations are unnecessary.

The solution: PERIsign

PERIsign is novel medical device that aid the healthcare professional to make a fast, objective and correct assessment of patient with acute abdominal pain. As of now, these assessments are subjective, uncertain and highly dependent on the experience of the examiner.

Cost effective

PERIsign detects if the patient suffers of peritonitis – the physiological response to severe intraabdominal illness.


PERIsign decreases the need of X-ray investigations and make the subjective, manual, investigation to an objective measurement. This increases ER throughput.
