Background: There are little data in the literature on the sensitivity of the urine trypsinogen 2 (UT-2) test in the diagnosis of acute pancreatitis, and results have been controversial. Also, studies of UT-2 test in the Indian population are few in number. The aim of the present study was to find the sensitivity and specificity of UT- 2 dipstick test for the diagnosis of acute pancreatitis in acute upper abdominal pain patients.
Material and Methods: One hundred-sixty-six patients aged between 18 and 80 years presenting with acute abdominal pain were included for this cross-sectional observational study. All the patients were tested with UT-2 dipstick test, serum amylase, serum lipase. Ultrasonography or contrast-enhanced computed tomography of abdomen was performed simultaneously. The diagnostic efficacy index such as sensitivity, specificity, positive predictive value, negative predictive value was calculated using the appropriate gold standard.
Results: The sensitivity and specificity of UT-2 dipstick test for detecting acute pancreatitis were 90.7% and 87.5% respectively. The sensitivity and specificity of serum amylase for detecting acute pancreatitis were 61.1% and 100.0% respectively. The sensitivity and specificity of serum lipase for detecting acute pancreatitis were 81.5% and 100.0% respectively.
Conclusions: The UT-2 test had good sensitivity and specificity and can be used reliably for the diagnosis of acute pancreatitis in acute upper abdominal pain.
