Overview
The 72 hr-fecal fat determination is the gold standard test for the diagnosis of steatorrhea
Diagnostic Study of Choice
Study of choice:
- Among patients who present with clinical signs of steatorrhea, the acid steatocrit is the most specific and sensitive test for the diagnosis.
- 72 hr-fecal fat determination is the gold standard test for the diagnosis of steatorrhea
- Greater than 6 gram/day of fat in stool is diagnostic of 72 hr-fecal fat determination in confirming the diagnosis of steatorrhea
- Patients with steatorrhea usually have >20 gram/day
The comparison table for diagnostic studies of choice for steatorrhea
| Sensitivity | Specificity | |
