Amoebiasis

It is reasonable, but not a uniform recommendation, to carry out a follow-up stool antigen detection test on completion of nitroimidazole and luminal therapy to confirm eradication of colonisation. UK guidelines specifically recommend that patients should undergo screening (via PCR testing of one stool sample) one week after treatment completion. Any case that remains PCR positive following treatment completion should be referred to an Infectious Diseases physician for further assessment.[24]Public Health England. Interim public health operational guidelines for amoebiasis (Entamoeba histolytica).

There is no need for follow-up imaging of an amoebic liver abscess after completion of therapy.
