Have you heard the joke about the lab technician that walks into the room to stick you with a 15” needle and draw your blood? Of course you haven’t that’s just not very funny stuff.
More than likely you are not as afraid of needles as I am, but I doubt anyone likes being told “I need you to roll up your sleeve.” Seriously do they really have to say out load “This is going to sting a little.” I pretty much guessed ahead of time that a long sharp object inserted into my arm would sting a little.
On a serious note though despite the anxiety I feel I am 100% aware of the very valuable insight that lab results provide physicians about my health so I reluctantly tolerate the “sting” and try not to cry until I’ve left. I tell myself I’m brave because I know that there are scaredy cats out there that don’t even see a physician due to their fear. When you are in the hospital it’s not as easy to hide from them though. The lab techs are generally at your bedside very early in the morning, more than likely waking you up, in order to remove a gallon of your blood, or however much those vials hold.
Your blood is then rushed to the lab where a technician runs the myriad of tests that the physician(s) have requested and then the results are generated. Until someone does something with the results of the lab tests the values are simply like all of the 0’s and 1’s that reside on our disks … useless.
In this post I’m going to discuss how I handled visualizing those lab results for the physicians rounding report I’ve been working on. I began my work on lab results the same way I would anything … “let me see what kind of data and what volume of data I’m dealing with.” LOTS and LOTS. I’m not kidding. It’s almost like every single drop of blood holds 1 MB of data or something. The following is for just the last 3 days of lab results for 1 patient.
You didn’t like having to scroll all the way down here to finish reading did you? It gets worse … I want you to scroll back up and figure out what the most recent lab result value is for HCT. Painful isn’t it. Certainly we are not going to deliver that as our lab results visualization.
