  • 1.  CLIA waived test controls storage

    Posted 05-22-2024 13:31

    Hi everyone, an interesting situation has come up and I need your help for data and evidence to make some informed decisions.  Best practices count. 

    • The situation is the storage of CLIA waived controls.  Many require refrigeration when not in use.  We do that and comply with the temp ranges. 
    • However, there seems to be no data on what happens if the refrigerator gets too cold (or too warm) and is out of range. 
    • We have commercial grade refrigerators and keep and monitor a thermometer in each unit. 
    • However, the thermometer is not a digital data logger (DDL) electronically connected to constant monitoring (like our vaccine storage freezers and refrigerators). 
    • We monitor Monday through Friday and would not pick up a temp excursion on the weekend.
    • When there is a suspect or confirmed temp excursion of an unknown duration of time - even if the control line indicates a valid result - manufacturers are silent on this in their IFUs (no data, since none is required by the FDA) and thus state "when in doubt, throw it out". 
    • It's getting expensive.    
    • Of course, when you ask the manufacturer and have some uncertainty – as we all do every weekend when we are not monitoring refrigerators -  or identify a temperature excursion of unknown duration -
    1. what are you doing for CLIA waived storage for controls that require refrigeration?  
    2. Is anyone using a DDL for refrigeration storage for specimen and CLIA waived controls?
    3. Can you store controls in the same refrigerator as vaccines? (in the past TJC said no, but I can't seem to find the reference). 

    I sent this out to our APIC community for a response also.  Please let us know what you are doing.

    In my ongoing search I did find a Q&A on the TJC site that states that meds cannot be stored in the same refrigerator as reagents and specimens.  However to check with our Board of Pharmacy. A

    Hi all, I noticed that some of my question was cut off.  When we call the manufacturer and we dont have specific info about how long a control/reagent is out of temp, they tell us to discard it.  But here's the catch, since there is no data or information even with adding the expense of a DDL we would most likely be instructed to discard the reagents also.

    In response to one one the questions regarding CLIA waived solutions, they cannot be stored with the vaccines. We were doing this and they had to be moved to a walk on refrigerator in the lab. (I work in a hospital) because biologics cannot be stored with medications. This was news to me because for years they were stored together. So now, controls are done in the lab which is on another floor which changed our work flow. This decision came from the system's point of care manager.

    thank you.  Any info about when a CLIA waived control is out of temp range.  We are being told that since there is no data on this (like there is for vaccines) that they have to be discarded.
