A patient has come to the clinic complaining of blood in his stool. A FOBT test is performed but is negative
Based on the patient's history, the physician suggests a colonoscopy, but the patient refuses, citing a strong aversion to the invasive nature of the test. What other test might the physician order to check for blood in the stool?
A) A laparoscopic intestinal mucosa biopsy
B) A quantitative fecal immunochemical test
C) Computed tomography (CT)
D) Magnetic resonance imagery (MRI)
Ans: B
Feedback:
Quantitative fecal immunochemical tests may be more accurate than guaiac testing and useful for patients who refuse invasive testing. CT or MRI cannot detect blood in stool. Laparoscopic intestinal mucosa biopsy is not performed.
