Infant Botulism Diagnosis & Tests
Physical examination shows the symptoms described above, such as decreased muscle tone (hypotonia), an absent or decreased gag reflex, absent or decreased deep tendon reflexes, and eyelid drooping (ptosis).
Laboratory testing consists of checking a stool sample to demonstrate the presence of botulinum toxin in the stool or demonstration of Clostridium botulinum in the stool.
A special muscle test known as electromyography (EMG) can help differentiate between muscle abnormalities and neurologic abnormalities.
