[Histonet] Giemsa controls

[Bob Richmond]

Tanya G. Abbott, Pathology Manager, PennState Health St. Joseph in
Reading, Pennsylvania asks:

>>Suggestions for where to buy good Giemsa controls for H. pylori?<

What I've always found satisfactory is to watch for positives in your own
material, evaluate them as possible controls, and use those. It would be
nice to have them verified by immunohistochemistry, but really the
morphology of each of the two Helicobacter species is sufficient.
