I am writing to report a highly unsatisfactory experience with Healthians Lab during a recent blood collection appointment on [insert date] at [insert time/location]. The lab representative assigned to me demonstrated a lack of skill in performing the venipuncture procedure. The representative struggled to locate and puncture my vein, resulting in significant pain during the process. Even after 24 hours, I continued to experience discomfort at the site, which I believe is a direct result of their inadequate technique.
