Abbott FREESTYLE Libre glucose in blood sensor

Sensor FreeStyle Libre is designed to measure the values of the glucose concentration in the tissue fluid. Easy to apply and wear, and allows you to get the value of the concentration of glucose painlessly for one second. To use is necessary to buy a card Reader FreeStyle Libre.

Product advantages

• The small size of the sensor FreeStyle Libre allows for a discreet and comfortable fit.
• This small, water-resistant sensor is worn on the back of the upper arm and lasts for 14 days.
• Unlike traditional measurement of glucose meter and strips, sensor FreeStyle Libre does not require daily pricking the finger.
• Sensor FreeStyle Libre does not require calibration using capillary blood obtained by inserting a finger, because it is calibrated already at the factory.
• Constantly measure the concentration of glucose in the extracellular fluid and stores 8 hours of data.
• Sensor FreeStyle Libre can wear even during showering, bathing, swimming, exercising.

Instant monitoring

The value of the concentration of glucose in the blood from the finger and the value on the sensor may not always match. The sensor measures the concentration of glucose in the interstitial fluid which surrounds the cells in the tissue under the skin. Thus, the measured values are compared to values measured from the blood to be delayed by about 5 to 10 minutes.

Indications for use

System for immediate glucose monitoring FreeStyle Libre a medical device indicated for the measurement of glucose concentration in the tissue fluid in people with diabetes mellitus (aged 4 years), including pregnant women. The indication for children (age 4 - 12) is limited to children under the supervision of a caregiver at the age of at least 18 years of age. The caregiver is responsible for working with the system, or help the child when working with the system for immediate glucose monitoring FreeStyle Libre, and also for the interpretation or assistance to the child in the interpretation of the observed values from the system FreeStyle Libre. The system is intended as a replacement for blood glucose testing in a separate treatment of diabetes with the following exceptions. Under the following circumstances use the meter to check the current values of the glucose concentration from the sensor system for immediate glucose monitoring FreeStyle Libre:

• At a time when rapidly changing glucose concentration, the value of the glucose concentration in the tissue fluid of the sensor and reported as a current may not accurately reflect blood glucose levels. When the glucose concentration falls rapidly, the value of the glucose concentration from the sensor may be higher than the level of blood glucose. On the contrary, when the concentration of glucose rises rapidly, the value of the glucose concentration from the sensor may be lower than the level of blood glucose.
• For confirmation of hypoglycemia or imminent hypoglycemia measured by the sensor.
• If the symptoms do not match the value recorded by the system for immediate glucose monitoring FreeStyle Libre. Do not ignore symptoms that may be caused by low or high glykémií.

Contraindications

System for instant monitored glucose FreeStyle Libre has to be before imaging magnetic resonance imaging (MRI) is removed.

Important notice

• Voucher may issue any diabetolog and is partly covered by the insurance company health insurance for patients with diabetes 1 type.
• Rarely they can be the values of the glucose concentration from the sensor inaccurate. If you believe that the value of the concentration of glucose is not correct and does not match how you feel, perform a measurement of the glucose from the finger to the concentration of glucose confirmed. If the problem persists, remove the existing sensor and apply nova.
• The performance of the system when used with other implanted medical device, such as pacemakers, has not been evaluated.
• The reader is intended to be used by one person only. Must not be used in vice people, including family members, because of the risk of spread of infection. All the components of the reader are considered biohazardous and can potentially transmit infectious diseases, even after performing the procedure čištěni.
• Some people may be hypersensitive to the glue that keeps the sensor on the skin. If you notice a big upset of the skin around the sensor or under them, remove the sensor and system FreeStyle Libre stop using. Before further use of the system FreeStyle Libre consult with your doctor or nurse.
• System for instant monitoring of glucose FreeStyle Libre contains male components that may be swallowed up by the dangerous.
• In times of rapidly changing glucose concentrations (more than 0.1 mmol/L per minute) glucose levels in the tissue fluid of the measured sensor system for immediate glucose monitoring FreeStyle Libre may not accurately reflect blood glucose. In these circumstances, check the value of the glucose concentration from the sensor when taking prick your finger to help the meter.
• To confirm hypoglycaemia or impending hypoglycaemia according to the sensor system for immediate glucose monitoring FreeStyle Libre perform the test by inserting a finger using the meter.
• Do not ignore symptoms that may be caused by low or high blood glucose. If you have symptoms that do not correspond to the values obtained by the system for immediate glucose monitoring FreeStyle Libre, or if you suspect that your values can be inaccurate, check the value of taking the test by inserting a finger using the meter. If you have symptoms that do not correspond to the observed values of the concentration of glucose, consult with your doctor or nurse.

System information

• System for immediate glucose monitoring FreeStyle Libre is intended to be used only with test strips for measuring blood glucose and ketone bodies in the blood FreeStyle Optium and control solution MediSense.
• Prevent access of dust, dirt, blood, control solution, water or other substances into the ports card reader (USB port and the ports for the test strips).
• The physiological differences between the tissue fluid and capillary blood can lead to differences in the observed values of the concentration of glucose. In times of fast changes in blood glucose, such as after a meal, the administered dose of insulin, or after trained can be observed the differences in the values of glucose concentration in the tissue fluid and capillary blood.
• Severe dehydration and excessive water loss may cause inaccurate results. If you believe that you are dehydrated, consult immediately a doctor or nurse.
