  • Sensor placement
  • Compression lows
  • Interference from medications or substances
  • Temperature extremes

Sensor Placement

To ensure accurate readings, placing the Sensor in the right spot is essential to avoid Freestyle Libre false low readings. Compression lows can happen if you put it on areas with a lot of body fat, like your upper arm or thigh. This occurs because the pressure from the fat around the Sensor can mess up its performance and make the readings look lower than they are.

On the flip side, sticking the Sensor in areas with a lot of muscle can also give you wrong Freestyle libre false low readings. That’s because the movements of your muscles can interfere with the Sensor’s measurements and make it seem like your glucose levels are low when they might not be.

So, finding the perfect placement for the Sensor is super important to get readings you can trust and rely on. Otherwise, you can face Freestyle Libre false low readings.

Compression Lows

Compression lows happen when the Sensor gets pressed down, like when you sleep directly on top of it or put on tight clothes that push against it. Another situation where compression lows occur is when you fall and your body weight forcefully lands on the Sensor, which also causes Freestyle Libre false low readings.

If the Sensor remains in place and doesn’t get damaged or broken, it will return to work once the pressure is relieved or removed.

Interference from Medications or Substances

Certain medications or substances can interfere with the accuracy of glucose readings. One such example is acetaminophen, a commonly used ingredient in many pain relievers. When acetaminophen is present in the body, it can lead to falsely lower glucose readings. This means that if a person takes acetaminophen while monitoring their blood sugar levels, they may get readings that appear lower than their glucose levels.

It’s essential to be aware of this potential interference and consider it when interpreting glucose readings, especially if acetaminophen or medications containing it have been recently consumed. Consulting with a healthcare professional is advisable for accurate glucose management.

Temperature Extremes

Suppose your Freestyle Libre Sensor isn’t giving you accurate blood glucose readings. In the case of Freestyle Libre’s false low readings, it’s essential to consider how temperature might affect it—extreme temperatures, whether too hot or too cold, can cause errors in the readings.

To ensure the Sensor works correctly, you must be careful when close to a burner or any other intense heat source that can affect the readings and cause Freestyle Libre false low readings. High temperatures can affect the Sensor, messing up its performance and making the readings unreliable. Similarly, exposing the Sensor to very low temperatures can also lead to errors.

The designers have designed the Freestyle Libre Sensor to achieve the best results within a specific temperature range. The Freestyle Libre Sensor requires maintaining a temperature range of 50℉ to 113℉ (10℃ to 45℃) in order to function optimally and prevent the occurrence of false low readings.

By keeping the Sensor within this range, you can help ensure that your blood glucose readings are accurate and that you can rely on the information provided by the device.

Symptoms and Signs

It’s essential to pay attention to the symptoms and signs that may indicate low blood sugar levels. These can include sweating, trembling, confusion, dizziness, hunger, and a rapid heartbeat. When you experience these symptoms, signals that something may be off your blood sugar, you should take action.

However, it’s crucial to remember that relying only on symptoms to determine your blood sugar level may only sometimes be accurate. There are situations where you can get Freestyle Libre false low readings, which can be confusing. Factors like sensor errors, medications you take, or external influences can sometimes give you misleading readings that don’t reflect your blood sugar level.

Make sure you have accurate and reliable information about your blood sugar; it’s recommended to use a reliable blood glucose monitoring device. By comparing your symptoms with the blood glucose readings, you can make informed decisions about managing your blood sugar.

For example, if you suspect low blood sugar based on your symptoms but the reading shows otherwise, you can adjust your actions accordingly. It’s also good to talk to your healthcare provider about any concerns or discrepancies between your symptoms and the readings. They can provide guidance and help you manage your diabetes effectively.

Confirmatory Measures

If you think that the low reading from your Sensor might need to be corrected, it’s essential to double-check using another method. One way to do this is using a traditional blood glucose monitoring device called a glucometer.

A glucometer allows you to get an independent and reliable measurement of your blood sugar level. Here’s how it works: gently prick your finger with a tiny lancet needle to get a small drop of blood. Then, the blood drop is inserted into a unique test strip into the glucometer. The device analyzes the blood sample and gives you an accurate reading of your blood sugar level.

By confirming your blood sugar level with a glucometer, you can find out if the low reading from your Sensor was accurate or if it was a mistake. This helps you make intelligent decisions about how to manage your blood sugar. For example, if your glucometer reading shows that your blood sugar is regular, you don’t need to treat it as low. On the other hand, if your glucometer reading confirms that your blood sugar is truly low, you can take appropriate steps like eating fast-acting carbohydrates or getting help from a healthcare professional.

Remember, if you have any concerns about the accuracy of your Freestyle Libre false low readings, it’s always a good idea to talk to your healthcare provider. They can provide you with the proper guidance and support to effectively manage your diabetes.

Calibration or Traditional Blood Glucose Monitoring

To verify the accuracy of the Freestyle Libre false low readings, it’s essential to conduct a calibration check using a blood glucose meter.

Here’s how you can do it: First, gather your blood glucose meter and test strips. Clean your hands thoroughly with soap and water, or use an alcohol swab to clean the finger you’ll be pricking. Next, insert a test strip into the meter as instructed. Then, use the lancet device to prick your finger and collect a small drop of blood. Apply the blood to the test strip, allowing the meter to analyze it.

Compare the blood glucose reading from the meter with the reading shown on your Freestyle Libre system. If the readings are close or within an acceptable range, it confirms the accuracy of the Freestyle Libre readings. However, there’s a significant difference between the two readings.

In that case, it may indicate that the Sensor needs recalibration, or there could be an issue with either the Sensor or the blood glucose meter. Consulting with your healthcare provider for further guidance is recommended in such cases.

Performing a calibration check using a blood glucose meter helps ensure that the readings provided by the Freestyle Libre system are reliable. It allows you to make confident decisions regarding your diabetes management and take appropriate actions based on accurate blood glucose information.

Compression Lows

One common cause of Freestyle Libre 2 False Low Readings is compression lows, when external pressure affects the Sensor’s performance. Excessive pressure can disrupt the functioning of the Sensor, which, in turn, leads to the Sensor displaying falsely low readings.

One effective solution to this problem is to change your sleeping position. Try sleeping on the opposite side of the body where the Sensor is attached. Additionally, placing a pillow behind you can help prevent unintentional pressure on the Sensor while you sleep.

Implementing these measures can reduce the likelihood of experiencing false low readings during the night. If the issue persists or you have concerns, consult your healthcare provider or the sensor manufacturer for further assistance and guidance.

Nighttime Dips

During sleep, it’s common for blood sugar levels to decrease slightly because our bodies require less energy at that time. The hormones responsible for raising blood sugar, such as glucagon and cortisol, produce lower amounts during the night, resulting in a natural dip called Nighttime Dips. Meanwhile, the body continues to release insulin, which lowers blood sugar.

The extent to which your blood sugar drops during the night can vary based on factors like your dinner choices, level of physical activity during the day, and even your stress levels. While there is a slight decrease in average, the Freestyle Libre 2 may overstate these dips and show false low readings.

If you’re worried about experiencing low blood sugar episodes at night, discussing this with your doctor is advisable. They can help you adjust your basal insulin rate, a type of long-acting insulin that helps maintain stable blood sugar levels throughout the day and night. By making appropriate adjustments to your basal insulin rate, you can prevent excessive drops in blood sugar while you sleep.

Conversation with your doctor about nighttime lows and the potential need to adjust your basal insulin rate can contribute to better blood sugar management and reduce the risk of hypoglycemia at night.
