Here's one so far - I'll keep thinking for other options.
What if her powers come from some ability to directly manipulate cells?
Status sense - Linh can interface with other's cells directly through touch, and by accessing the nerves she can inspect the target's injuries. If at range, maybe it would operate over some kind of pheroemones? Or those could be limitations.
Shield - instead of a true shield, she can hold out her hand and block things, kind of like Vader does in ESB. She can cause the cells in her hand to 'harden' (as in defense prepartions and not hard like steel) and prevent damage from the incoming attack. Until you make the shield mobile, she could only do it while concentrating (and thus have to stand still). Maybe some more restriction points there, I dunno we'd have to look at it.
Healing power - a la Status Sense
Attack power - well it'd make sense as a touch attack, manipulating cells to harm. If ranged, I'm not sure - debilitating phereomones?
Creat Object? What are you planning to do with that?
