5 Must-Follow Steps To Calibrate Your Blood Glucose Meter Correctly

It is important for people to check their blood glucose level once in a while to see if they are diabetic or within the normal range. Especially for diabetic patients, it is extremely important for them to always monitor their blood sugar level. You may consider this a precautionary measure for yourself so that your blood sugar will not increase up to dangerous levels. Of course, in order for this to work, you have to ensure that your glucose meter is properly calibrated. Otherwise, what is the point of checking? You will not get the correct results anyway. So for diabetics out there who own one, here are the correct ways to calibrate it before you can start using it for your test.

5 Must-Follow Step To Calibrate Your Blood Glucose Meter Correctly

  1. Firstly, you have to check the code on the test strip vial. This can usually be found in bold print.
  2. Next, turn the meter on. Most units automatically do this once that you place the test strip inside. The test port can usually be found either on the top of the meter or at the bottom area.
  3. You can tell that the meter is not properly calibrated if the code that appears on the test strip vial does not match the one on the meter. If the meter is brand new and has never been used before, it is highly possible that it does not have a code at all. A flashing blank space will be displayed instead.
  4. The calibration process starts the moment when you set the code into the meter itself. How do you do that? It depends on the unit that you have. There are some meters that come with up and down arrows while some have only one button. Just continue pressing the button until you see the code that matches the vial.
  5. The last step is for you to test if it works by taking a blood sample. Once the test is complete and the display on the blood glucose meter is correct, you will be sure that it is properly calibrated. The easiest way to determine if your readings are accurate is by bringing it to your health care providers and check against the readings taken using their glucose meters.

Here are some important points to remember before you calibrate blood glucose meter. First, always make sure that the codes match (the code on test strip vial and the one on the meter). Second, use it until you are very familiar with it. Remember, each unit is different depending on the brand and make. Third, the code numbers should match at all time. Fourth, never use outdated strips and never bend them too.

8 Common Mistakes That Affect The Accuracy Of Blood Glucose Test Reading

Most blood glucose testing meters sold in the market are precise and accurate since they have been heavily tested and checked by the experts in labs before approval for sale. In most circumstances, the accuracy of test reading are affected by mistakes made by consumers or users whom are doing the test. Here are 8 common mistakes that we have observed.

1. Contaminated meter or testing strip

Meters that have not been properly cleaned and contaminated with old blood may cause false high or low readings. Testing strips that have been used should be thrown away after each use. In addition, storage of strips should be secured at all times with the cap tightened.

2. Meter or testing strip not within the normal room temperature

Meters or testing strips that are exposed to either too high or too low room temperature will cause false reading. Be reminded that you should always keep all your blood testing equipments in a dry and normal environment. Avoid them from the reach of your children if possible.

3. Expired or used testing strip

Strips that have been outdated or used in previous test should be kept away whenever a new test is to be performed as they may affect the result too.

4. Uncalibrated meters

You should calibrate your meter for it to have a correct code matching the test strips you are going to use. Always remember to perform your calibration before any test to ensure reading accuracy. As some meters calibrate automatically, you may like to put this into consideration when choosing your blood glucose meter.

5. Too little or large drop of blood

Too small a drop of patient blood for testing may also give a false low reading. Patients should remain calm and relaxed at all times. In addition, there should not be an over-squeezed amount of blood too.

6. Strip not fully inserted (may sound silly but it really happens)

One most common mistake is that the testing strip is not fully inserted into the meter while performing test. Most people are usually not aware or ignorant about this. Learn more about how to correctly perform a blood glucose test using a meter.

7. Low in battery

When low in battery, the performance of the meter may be affected and thus resulted in unreliable results. In worse case, it may cause the inability to power on the device or sudden failure of the device due to dead batteries.

8. Patients with anemia or dehydration symptoms

Test conducted on patients with anemia or dehydration symptoms may face false high reading problem too.

Always bear these 8 factors or mistakes in mind before performing any glucose test at home as an undesirable false reading may be in worse case, cost a human life.
