  • My favourite magic box is the MALDI. Matrix Assisted Lazer Desorption Ionizer. You mix matrix with bacteria from culture on a slide. The machine fires a lazer at the slide and breaks it into ions (charged particles). They’re sucked up into a tube that measures mass/charge ratio by seeing how long it takes those particles to travel down a tube before they hit a detector (its mass spectrometry/time of flight). The signal it makes generates a fingerprint that is compared to a database… and it tells you exactly what bacteria you’ve isolated based on those fingerprints! Its the greatest invention known to man!

    I’m in a med lab program and they talk so much shit about nurses in our lectures (no offence). They even hire actors and we do conflict resolution exercises like phoning an exhausted nurse to let her know her third draw just got rejected and they need another sample or order of draw problems ect…
