Below are pathology unknowns cases in which you can order immunostains and, for some sets, molecular studies such as karyotypes, FISH, and sequencing. Choose your case, and when presented with a text box, begin typing the immuno or other study you'd like, and select it from the Autocomplete list. Type "Presentation" to see the answer and explanation. Use "Ask Brett" for a hint.
