Quality control material

Recommended Posts

Greetings,

We use the Ortho Confidence system to QC our wet reagents. I have been alerted that there will be a delay in the next lot number shipment due to the (US) government shutdown. The current lot that we are using expires 10/29/2013 and the new lot # is set to ship on 10/30/2013.

 

My question is, can I use patient samples that have established values for QC testing for the couple of days that I am without unexpired QC material? If so, how many examples of a particular value do I have to have in order for it to be a valid QC evaluation? For instance, if I want to use a group A patient to QC the anti-A reagent, how many times does that patients blood group have to have been tested?

 

Thanks for the input.

We don't use the Ortho Confidence QC system, so I am not familiar with it.

However, rather than trying to use multiple patient samples as "interim" QC material, wouldn't it make more sense to just continue to use your expired Ortho QC material (as long as the QC test results were satisfactory)? (And, of course you should document why you used expired QC material in your QC records.)

You should have something in you quality plan that lets you (via your medical director) do things out of the ordinary - like use outdated materials (which still work fine) due to circumstances beyond your control.  I have had an occasion to have to use outdated reagent A1 and B cells due to manufacturing delays.  Not having a stock of B neg rbcs my process allows my MD to okay continued use of the outdated cells until the new materials arrive (or tney no longer function as anticipated).  This is not a carte blanche/across the board ok - each individual event gets its own entry into our quality review system.  These events are rare but they do occur.  Activate the portion of your quality plan that lets your MD okay the use of the outdated QC materials for an extra day - as long as they work as expected you should be fine (in my opinion).

      Silly question...,but I'd really like to know,what is the difference in choosing between human and monoclonal reagents for ABO/D testing? Is it a first choice from these two?Is it the price?
      I work with Bio-Rad reagents and I know they have cards with human reagents but also identical cards with monoclonal reagents.Our lab use only monoclonal ones.

      We are in the process of choosing new Coag. analyzers and have narrowed it down to IL and Siemens.  I was hoping to get opinions on the liquid protime reagent for the Top 350s that IL says is available.  Also how is their Heparin Xa reagent.  We have a CA1500 now and would change to the CA2500 but I have been having some QC issues lately but my instrument is only 12 years old.

      Hi Everyone,
      I just joined the website and I am hoping that my fellow laboratorians can help me. I recently finished a Joint Commission survey at my facility and I need to write (1) an IQCP for the media that we use in the Microbiology Department as well as (2) an IQCP for the Beckman Coulter MicroScan. I was hoping that someone had a template that would help point me in the right direction. Of course, aspects of the risk assessment (e.g. testing personnel, environment and so forth) will be specific to my facility but it would be great to have something to help point me in the right direction.
      So if anyone could provide me a copy of their template that would be FANTASTIC!!!
       
      I REALLY need an IQCP for the Media and one for the Microscan would be fantastic as well!  
       
      Thanks in advance everyone!!

      We have been having problems for the last month or so with D-dimer QC on our TOPS analyzers.  We are using the regular HemosiL reagents and controls, and no matter what we do, the QC runs with a Mean close to the upper insert range limit on both controls.  Does anyone else have this problem?  
      We have been using these analyzers and IL products for over a year and now this happens. We are wondering if the formulation of the QC has changed.  Once reconstituted, they are supposed to be good for a month in the fridge -- it appears to us that they may be only reliable for about a day. 
      Thanks, Scott

      I need some guidance!  I did a quick search of the forums for any discussion about this, and the most current posting was in 2010.  I'm wondering if anyone has any new information, new experiences, or any advice about CAP TRM.40120.  The note states "...all analysts participate in QC on a regular basis."
      How frequently is "regular"?  For example, when I was looking to complete our annual Competency assessment in September (don't ask...), I was looking for evidence that each individual who performs MTS testing had performed MTS QC.  There were some employees who had not performed MTS QC yet in 2016.  I'm inclined to say that someone who hasn't performed QC in at least 8+ months is not participating in QC on a regular basis.  Being new to my role, I'm just not sure how the assessors interpret this standard, and how others provide evidence of compliance.
