Coaguchek xs test strips.recall

[sharky7]

why is he wrong?

I'm going to call you wrong for assuming that the count was exclusive.

oh ya, i know we all have two lives, my anger goes to cats, why do they have nine lives when I dont have 9......I want, no, I DEMAND my 9 lives!!!!

Hello everyone,

I just want to double check i understood this issue with these strips.

The strips with the serial numbers mentioned REF160 are they still good to use as long as the INR is below 4.5? to the people with the strips with this REF number are you still using them and getting accurate results?

i ask this as i got my CoaguChek machine a few weeks back but was a bit hesistant to use and started using it two weeks ago and noticed the strips i bought are REF160 and today i did my first LAB vs CoaguChek comparisson.

I did my test with CoaguChek with a result of 3.6 INR then 30 minutes after had my blood drawn for the lab for my test and my result was 2.8 INR which are very different results and just to double check once i recieved the lab results i did another test with my CoaguChek (5hours are the first test) and my result was 3.7 INR.

Going to try this again on friday to see if the lab did a mistake or if the strips are no working for me.

Do i have to calibrate my machine? if the answer is yes how do i do that?
How can i test if my machine is working correctly?

This issue occurred in 2018, so the affected strips are long expired now. In my post from 2018 on this thread I linked to the Roche announcement - see here - which lists the affected batches.

You can test your machine by doing a test at the same time as doing one at your anticoagulation clinic. You should get the same result as them, +/- 0.2

Edited to add: Since codes are only three digits long, there can only be 999 of them. I don't know this for a fact, but I would therefore assume that codes are re-used and even if a code was the same as one shown in the list of recalled strips, it would only be a problem if the REF number (on the box) also matched.

ooh thanks very much for the detail about the ref number, i will try and test friday again with the lab at the same time to check.

Hi

Given @LondonAndy 's capable response I'll just add a bit more on this point

the beauty of the XS is that you can not calibrate it, calibration is done in the factory which is why strips have a code chip. That's where the calibration is done.

And really ... would you trust the general public to calibrate an instrument? The unit itself does nothing more than record the times provided by the strip data (well and its an analogue process not a digital one).
