App-derived interpretation

Unknown reason.no_named_rule · v1.0.0
potential contamination with potassium hydroxide may have an impact when performing immunohistochemistry testing. It is unknown whether the contamination will affect tissue antigenicity. If it were to affect tissue antigenicity, the outcome would be risk of false positive or false negative test results which may lead to serious injury. There is the possibility the patient may need to be re-biopsied.
