This is what our happy clients have to say


  • I would like to let you know that I am very satisfied with this meter. I have been using the meter now for 2 months. The first two times, in consultation with my doctor, I compared the measurements of my home test (made on the same day) with the results from the doctor/laboratory. I was pleasantly surprised (my doctor too) about the results. The results were the same. I can now confidently measure my cholesterol at home and I don’t need to go to the hospital for that.

  • Professional meter and highly accurate measurement also at home. I am very happy with the test results as they correspond exactly to those from the lab via the GP. So I can confidently use this meter to monitor my cholesterol. Very glad I found this meter, saves me lots of time!

Frequently Asked Questions


On Call Glucose Meter

  • What values does the On Call Glucose Meter measure?

    The On Call Extra Blood Sugar Glucose Meter measures your glucose within 4 seconds with only a tiny amount of blood, thanks to the unique test strip. Test both capillary and neonatal blood. The devices are ISO 15197 certified and thus provide reliable and – clinically proven – accurate results.

    The On Call Extra can also store up to 300 measurements, giving you insight into the course of your glucose value. It even gives you a Hypo, hyper and ketone alarm, so that you can do something about it.

    The device is very handy and easy to operate – thanks to the large push buttons – and makes it easy to measure your glucose at home or on the go. The meter works on batteries and is suitable for professional and home use.

  • I live outside the EU, can I still order?

    Yes, we ship worldwide. Please check our shipping rates on our delivery & returns page.

  • Can I use a teststrip more than once?

    You can’t use a teststrip more than once, because the strip wouldn’t be able to recognise the correct blood values, due to clotting effects after dropping blood on the strip. Each measurement requires a new strip.
