CoaguChek XS Meter Working Fine

Today wife went to do a blood test at NUH, INR was 1.3, then at the same time also checked using our meter, also 1.3, this means that the meter is still accurate, so I think previously why shot up so high is because we lost track.

Before she was warded, last check was on 17 Sep and the value was 1.8, after that we checked at NUH A&E and it was 6+. I think safer is to check at least twice a month, if somehow meter doesn't work again then better go check at NUH or polyclinic.

So now one thing for sure is that if reading is too high, for example 6+ then the meter will not be able to produce reading and may show QC or error 6.

Today the cost for checking at NUH is $25, after subsidy is $18.75.
