Trivia for the bench: per CLSI guidelines, what’s the minimum clot time you document before spinning an SST, and how do you verify compliance during result validation? We caught a 9:12 a.m. ED draw spun at 9:22 on a StatSpin that bumped K+ by 0.5 mmol/L, and I’m wondering who else flags these in audit logs.
We document 30 min per CLSI (GP41) for SST — up to 60 min if the patient’s on anticoagulants — so a “9:12…9:22” spin would be auto-flagged. Our middleware checks collection-to-spin time and hard-stops anything <30 min unless it’s an RST, then forces an override comment that we review in validation — do you audit those overrides too?
