Test University Hospital Tube
Crystals Plain Red Top (no additives)
Protein, Glucose
Gram Stain and Culture
Cell Count Lavender (deep purple, same as CBC tube)

You can send Bactec bottles for a culture, but if you want a gram stain you must send a red top.
If you send a red top only, you may be able to get a gram stain and culture, but I'm not sure, I still have to ask.
