Something Wrong with Wife's CoaguChek XS Meter
Recently the device keep showing QC error, wasted quite a few test strips and still unable to get a reading, I think wasted like almost a bottle of the test strips, one bottle have 6 and cost $64.20 after GST. And that's how we lost track of her INR level. Should have bring her to NUH to check instead of waiting. Last Saturday when we went to NUH , I tried looking for the test strips at the Clinic A pharmacy but they don't sell, the pharmacist told me to try the one at the Medical Centre at level 3, good thing they sell so I bought two bottles. After that tried one and got error 6, I think it's because wife's INR was too high so the device can't read it and show error instead. By the way if you want to know more about the error codes you can see this link for the user manual. I also found a link at HSA which says INR value greater than 8 can cause error 6, but wife's reading was 6+ based on NUH A&E blood test but the meter shows error 6, very confusin
