IG-23 Red Tag Out, Green Tag In

1 · Fault found — tag it out

🔴 RED TAG — OUT OF SERVICE

Defective performance, optical errors, or repeated QC failures? The instrument is removed from service immediately and tagged.
Review patient specimens tested between the last satisfactory check and the failure.
The CMT notifies clinical units of testing delays.
Downtime and repair chronology are documented in the equipment service log.
Arrange alternative testing — backup analyzer, referral laboratory, or STAT diversion — per LAB-QM-IT-002.

After repair: perform recalibration, precision checks, and routine QC testing.
Decision: does testing confirm satisfactory operational status?

🟢 GREEN TAG — IN SERVICE

Satisfactory: the CMT authorizes return to service; attach the Green IN SERVICE tag. Patient testing resumes.
Not satisfactory: the instrument remains Red-tagged OUT OF SERVICE, quarantined from diagnostic use.
