You can use the built-in meter to check your blood ketone levels using FreeStyle Optium b-ketone test strips. You should perform a blood ketone test on your fingertip only. Be sure to read the test strip instructions for use prior to using the built-in meter.
'Flash' reflects the fact that users can obtain glucose readings quickly by just scanning the reader over the sensor. Flash glucose monitoring also provides a flash of insight to people with diabetes and their healthcare professionals.
No, the FreeStyle Libre sensor is calibrated during the manufacturing process so you don't have to. The sensor is activated by scanning and then, after a 1 hour warm up period, it starts to record glucose readings automatically.
Traditional blood glucose monitoring provides users with glucose readings that represent distinct points in time. Users do not get information regarding how their glucose levels have been changing, nor do they get information about where their glucose levels are heading. Without such information, it can be easy to miss significant glucose fluctuations - the ups and downs. The FreeStyle Libre system is a new way to obtain glucose readings. It allows the user to get their current glucose reading by just scanning the reader over the sensor, and also provides a complete picture of glucose variations.
The FreeStyle Libre Flash Glucose Monitoring System is indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with diabetes mellitus. The indication for children (age 4 - 17) is limited to those who are supervised by a caregiver who is at least 18 years of age.
The caregiver is responsible for managing or assisting the child to manage the FreeStyle Libre Flash Glucose Monitoring System and also for interpreting or assisting the child to interpret FreeStyle Libre readings.
The insulin calculator utilises settings entered into the insulin calculator during one of two setup modes (Easy or Advanced); this feature requires an understanding of the use of insulin and must be set up by a healthcare professional. Using the settings they enter, the glucose reading from the built-in blood glucose meter and carbohydrate information (in grams or servings) the user provides, the insulin calculator software in the reader calculates a suggested insulin dose.
No, the insulin calculator can assist you with calculating rapid-acting (meal-time or short-acting) insulin doses only. The insulin calculator must be set up by a healthcare professional.
'Easy setup' is for users who use a fixed dose of rapid-acting insulin before meals. 'Advanced setup' is for users who count carbohydrates (in grams or servings) and/or use a correction factor to adjust doses of rapid-acting insulin at meals. The insulin calculator must be set up by a healthcare professional.
Both the reader and the sensor should be stored between 4°C and 25°C.
The FreeStyle Libre Flash Glucose Monitoring System offers a Trend Arrow with each glucose reading which tells you which way and how quickly glucose levels are changing. So, at any given time, you not only know what your glucose level is currently, but also which way it is heading. Depending on the direction of Trend Arrow, you can find out if your glucose levels are going up, down or staying steady, facilitating better decision-making.
Abbott Diabetes Care is committed to making its products safe for the user. After the insertion, the sensor and the body need to equilibrate (or settle). We have found through our research that it is not always easy to accurately measure glucose in the body until this equilibration happens. Therefore, we let the system equilibrate for 1 hour to make sure that it is providing accurate glucose readings.
No, the reports are available only when the reader is connected to a computer. However, you can send the pdf version of your reports to your healthcare professional via e-mail (with your healthcare professional's permission).
FreeStyle Libre sensors are programmed for sale in a specific market and are compatible with readers sold in that market:
- FreeStyle Libre sensors in one market are not necessarily compatible with FreeStyle Libre readers in other markets.
- FreeStyle Libre users should plan on purchasing sufficient sensors from the same country they purchased their reader in, to last the duration of their travel.
