Another Freestyle libre Issue. (Sickle cell trait)

    Hi Dia-tribe

    I have a quick question that I know some of you will be best placed to answer.

    What should the difference be in readings between the freestyle libre and a blood prick (I use my palms as a testing site)?

    Last night the reader gave me a reading of 3.2 but I knew that wasn’t right so I FP and the reading was 5.9. I had a waking reading of 7.2 on my sensor this morning but FP showed 9.8.

    I have a sickle cell trait that affects the shape of my blood cells and I have to have another truer test along with my HBA1C to give me a true indication of my diabetes management.

    So I’m wondering is the differences in reading normal in the FSL or do I need to be concerned?

    Thanks for reading and hopefully answering.

    I find that happens with some sensors. Collect at least 3 results, include the date and time of the pairs of results (sensor and FP) and also the direction of the arrow for the sensor reading. Ring Abbott helpline and tell them. They should send you a replacement sensor with return packaging.
    Some sensors are just worse than others.
