Tell her I feel for her. As a result of normal physiological variation, some individuals may have small, thin, or hard-to-find veins, making it a challenge for even an experienced medical lab technician to draw blood. This can sometimes be a result of dehydration, which causes the body to constrict its blood vessels.
I had a really senior lab tech tell me one time that certain people have rolling veins caused by the collagen in tissues that anchor veins in place are weakened, causing the vessels to roll when approached by a needle.
Shes usually like that, she saw one nurse last year that nailed it first time and it was mentioned so the nurse told her what to tell the next person who did it, basically use x needle, of size and take it here. She tried that and it really annoyed the person, so she doesnt mention that anymore. |
