Natalie’s sodium levels have to be monitored, so Noemi, the lab tech was called in to take a quick blood sample for the test (note the silver bandage on Natalie’s right middle finger). She also has a daughter named Natalie, which is a very special name. Sodium levels look good.  There was an initial concern because Natalie’s urine output was high, which is a sign that sodium may be off – and this is a particular concern with brain surgery.
