Took an ATP swab on a pen after sanitation; reading 412 RLU at 6:15 a.m. — higher than a floor drain — while the line passed at under 10. I now have a policy: pens live in the pen cup, not the filler; any other “silent biohazards” you’ve caught that made you rewrite a SOP?
That ‘412 RLU at 6:15 a.m.’ tracks — our badge reels beat the floor drain too. We killed reels, switched to stainless pens on a short tether, and added the touchscreen stylus to pre-op ATP with an hourly 70% IPA wipe. If you haven’t yet, swab the stylus and glove cuffs next; they’re sneaky.
Swab your tape-gun handles and marker caps — ours beat ‘412 RLU’ at 6:15. We added pre-shift 70% IPA wipes.
I’m with you; my tweak is placing a verbal ‘1 g CaCl2 with the first unit’ order when I pull MTP to blunt the citrate drop and keep the pressure from cratering… I still ‘call early, cancel fast’ once the A-line trends settle — do you bundle
And quick example: we pre-alert and send low-titer O whole blood first; the one tweak that helped was a hard 5-minute checkpoint to downshift if the A-line and exam settle. > “positive FAST” — agreed as a trigger, but not a blank check; @bloodbankMike, are you seeing faster turnaround with whole blood vs 1:1:1 at night?
Your ‘pen cup’ rule tracks; swab the glove-box slit — ours outgunned the pen at 6:15; switched to closed dispensers.
Badge lanyards were our biggest “silent biohazards” — turns out they’re friendship bracelets for microbes; we swapped cloth lanyards for smooth reels and added a clock‑in wipe pass for the reels and RF scanner triggers. Have you swabbed the E‑stop mushrooms or the underside of clipboards yet?
