After all the concerns about the test strips and the discrepancies I had with codes 309 and 311, I was understandably very anxious about going abroad when I couldn't be sure the test strips would give me an accurate result. Was there any point of doing a test because what if the result was high? Should I change my dosage? I decided to take reading on Thursday but leave the dosage the same. Reading was 4.5.
Then I did a reading on Sunday when we got back home 6.7. This is the highest reading since I started self checking about 8 years ago!
So I took my coaguchek to the surgery on Monday to compare test strip readings with their coaguchek. This was done immediately after each other.
Surgery coaguchek (code 263) 4.4
My coaguchek (code 311) 5.5
We then checked to make sure it wasn't my machine that was faulty by putting the surgery chip code in my coaguchek and used one of their test strips - 4.3
So it must be a test strip problem!
I have emailed these results to roche having contacted them last week about the problem. They have asked me further questions and are now sending my results for investigation.
So please be careful when using the test strips atm and get the results compared like I did to check for discrepancy. Venus testing will usually be different. Coaguchek to coaguchek should be virtually the same , not 1.1 difference!!!
