Come to work, not sure if I'll be running blood. Find out an hour later that I would. Start to get all set up. The Coulter (a cell counter) won't pass the high control. Run it again and again and again. And again. No success. Get a new control from a different box, enter the new numbers into the spreadsheet, run the control. The Coulter passes! Realize the other Coulter was run on the other control. It's now out of specification, must be redone. Run the control on it. Again and again and again. It all passes but one parameter and it's off by one measly platelet. Go to run the control one more time. It slips out of my hand. Crash! Crack! Splatter! There is a puddle of blood on the floor splattered. It's on my shoe. Pout. Clean up the broken glass and puddle of blood. Bleach my shoe, drench it, multiple times. Decide I'm fed up with the Coulter, turn it off. Realize I turned off the Coulter that had passed the controls. Feel really frustrated. Turn the Coulter back on. Rerun all controls. Get the other high control from the new package, start mixing it. Notice it's not mixing right, realize it has been frozen. Run it anyway. Need a reading of ~425, getting a reading of ~1520. More frustration. Throw the previously frozen, now thawed control in the biohazard. Turn off the Coulter again. Justify the non-passing parameter on the other Coulter (it wasn't a production run). Continue with the blood run. Finally get to the first point just before noon. Starving. Units ready at noon and need to be run. Wait. Run units. Take a break to eat. Breathe. I smile and have a good day.
