Hi there, I am a senior doing a term paper on medical errors and miscommunication that occurs throughout the medical field. I am using my grandma as an example in the paper because a nurse didn't draw her blood for two lab tests like she was ordered to. Instead, she just took one and my grandma became very ill when she was released home. The lab test was for blood thickness. Due to her history of strokes, she was on blood thinners which is why the labs were ordered. My mom had called the hospital and a nurse had told her that my grandma's labs weren't drawn and she was taken to the ER. Well it turns out that her blood viscosity level was at 11.1. My mom works in a hospital and she knew it was bad, but i was wondering what the normal range for blood thickness was. I could use some help.
