Is there a relationship between how much blood is sucked on a blood glucose test strip and the resul

Of course, it will be affected, and the impact is still great, and the knowledge in the blood glucose meter test strip is very great. Let's teach you a few tricks first!

1. Operation method: When using a blood glucose meter, the test strip operation will directly affect the test results. To perform the test strip operation correctly, the main attention is to whether the test strip is inserted into the blood glucose meter in the correct direction, whether the test strip is bent, and also pay attention to the position of the test strip.

2. The storage of the test strip: whether the storage of the test strip is proper is also one of the key factors affecting the accuracy of the test. The storage of test strips should be operated in accordance with the provisions on the instructions.

In principle, it is required to close the lid of the test strip immediately after taking out the test strip to avoid moisture or oxidation of the test strip. In particular, it should never be put together with volatile items, such as alcohol. Different brands of test strips use different enzyme technology, so the validity period is also different.

Some test strips can only be used for 3 months after opening, while others, such as Roche, can be used until the expiration date, up to 24 months. Expired test strips can also directly affect the results of the test.

3. Test technology of test strips: Most of the blood glucose meter test strips on the market use glucose oxidase technology and glucose dehydrogenase technology, which is easily affected by many factors in life, because this technology is easy to be interfered with by oxygen. Asthma, smoking, emphysema, and various cardiovascular diseases can affect blood oxygen levels, as can altitude and strenuous exercise.

Glucose dehydrogenase technology, on the other hand, is susceptible to intravenous maltose injection and maltose-containing drugs. Both have their own interfering factors, and users should follow their doctor's advice and pay attention to contraindications when testing blood glucose.

pH test strips? Generally, the test strip of the blood glucose meter is used, but the test strip corresponds to the corresponding blood glucose meter, so you should buy it from the medical device ** merchant who purchased the blood glucose meter. If you say that you just use a test strip to measure blood sugar, there should be none, and even if there is, it is not accurate, because there is no such test.

Must pass through the instrument.

Hello, at present, the mainstream blood glucose test strips on the market all use the automatic siphon function.

Prick your finger and bring the blood slightly close to the blood collection hole of the test strip, and the blood will be drawn in automatically.

There are two differences in the working principle of blood glucose meters, one is photoelectric type and the other is electrode type.

The photoelectric blood glucose meter is similar to a CD machine, there is a photoelectric head, its advantage is that it is relatively cheap, the disadvantage is that the detection head is exposed to the air, it is easy to be polluted, affecting the test results, the error range is about plus or minus, the service life is relatively short, it is generally more accurate within two years, and it is recommended that the patient who is using the photoelectric machine go to the after-sales service repair station to do a calibration and bald head maintenance after two years. Johnson & Johnson's steady, steady, Roche's Lekangquan, Luo Kangquan and so on belong to this type.

The test principle of the electrode type is more scientific, the electrode mouth is built, which can avoid pollution, and the error range is generally about plus or minus. High precision, under normal use, no calibration is required, and the service life is long. Its representative products are Roche Superior, Japan Kyoto 1640, Korea Woodpecker, Abbott Anto, Lisutan, Johnson & Johnson Wenhao and so on.

There are two types of blood glucose meters from blood collection, one is blood drop and one is blood sucking.

The blood glucose meter generally collects a large amount of blood, and the patient is more painful, and the typical machine in this regard is Abbott's early product QID blood glucose meter. If the amount of blood dropped in this blood glucose meter is too much, the test results will be affected, and if the amount of blood dropped is insufficient, the test will fail, and the test strips will be wasted, so the operation is difficult to master.

Blood glucose meters are mostly photoelectric type.

The blood-sucking blood glucose meter, the test strip controls the blood sample measurement by itself, and the result will not deviate due to the problem of blood volume, and it is easy to operate.

Blood-sucking blood glucose meters are all electrode type.

Nowadays, most blood glucose meters are invasive, that is, blood needs to be collected, for patients who need to measure blood sugar many times, although there are non-invasive blood glucose meters available, but ** is very high! In order to alleviate the pain of fingerstick blood collection, a blood glucose meter with multiple blood collection sites can be used, and a blood glucose meter with a small blood collection volume (1 to microliters) can also be selected.

There are two main principles of blood glucose meters: electrochemical and photochemical principles. The electrochemical method directly measures the microcurrent generated by the reaction zone of the blood glucose test strip; The photochemical method to test the change value of the absorbance of the blood glucose test strip, the sample area of the test strip must be directly in contact with the light hole, which may lead to the contamination of the light hole, therefore, the blood glucose meter of the photochemical method must be cleaned frequently, otherwise the contamination will lead to the deviation of the test results.

In general, more blood samples are required for photochemical tests than electrochemical blood glucose meters.

The depth of blood collection should be adjusted at 3It is usually pierced in the middle finger. It's all like this.

The first few times you adjusted it a little deeper, how deep it was, how deep it was, and if you can't tie it out, you have to tie it a second time. Too shallow will affect the measurement results. The blood glucose meter should not suck too much blood, and it is good to adjust the scale yourself when you are proficient.

1.Wash and dry your hands thoroughly.

2.Warm and massage fingers to increase circulation.

3.Hang your arm down briefly to allow blood to flow to your fingertips.

4.Use your thumb against the interphalangeal joint to be collected, and then use the lance to puncture the side of your fingertip**.

5.Do not squeeze the skin after pricking, so as to avoid the tissue fluid mixing into the blood sample, resulting in deviation of the test results.

Squeezing your fingers when measuring blood sugar can cause inaccurate resultsWith the popularity of home blood glucose meters, many diabetic patients have developed a good habit of measuring blood sugar frequently. However, if you measure diligently, you don't necessarily have to measure accurately. "Some elderly people come to the hospital and call as soon as their blood sugar is measured'It's not that high at home!

Is the machine inaccurate? 'After talking about the details, I found out that it was not that the instruments at home were not good, but that they were useless. For example, many people have the habit of squeezing their fingers when measuring their blood sugar.

Doesn't seem like much. However, squeezing the finger to make the blood volume sufficient, it also brings out the tissue fluid. In this way, the blood is diluted, and the measured blood sugar level is naturally low.

Zhuang Xiangkang told reporters that if the amount of bleeding is not enough, after the needle is pricked, gently push the blood vessels on both sides of the finger to one-third of the front end to let the blood slowly overflow.

Once squeezed the finger affects the glycemic index.

The correct one should be:

Step 1: Wash your hands with warm water or mild soap, rub your fingers repeatedly until the blood vessels are abundant, then disinfect your fingertips with 75% alcohol and wait for them to dry.

Step 2: Turn on the switch of the blood glucose meter, use the blood-sucking blood glucose meter, take a test strip and insert it into the machine; With a blood glucose meter, take a strip of test strip and hold it in your hand (fingers should not touch the test strip test area).

Step 3: After taking out the test strip, close the cover tube tightly, use the blood collection pen close to the fingertip, press the spring switch, and prick the fingertip. It is best to take blood on both sides of the ring finger, because of its abundant blood vessels and less distribution of nerve endings, it is not only not painful but also has sufficient bleeding.

Step 4: If it is a blood glucose meter, suck the blood into the dedicated area of the test strip and wait for the result. If it is a blood glucose meter, a plump drop of blood or wipe it on the test strip test area, insert the test strip into the machine and wait for the result.

Do not add additional blood as this will result in inaccurate test results.

It should be that the machine has exceeded the time to wait for blood to be sucked (it is necessary to quickly suck blood after the machine recognizes the test strip). Also check that the test strip matches the model of the blood glucose meter used.

It depends on whether you are buying it in **, whether the battery is out of power, and it is also possible that your blood collection has timed out and the machine will automatically shut down. You can go to the place where you bought it and exchange it.

1.Wash your hands with warm water or mild soap and rub your fingers repeatedly until blood is abundant. Disinfect fingertips with 75% alcohol and allow to dry.

2.Turn on the switch of the blood glucose meter, use the blood glucose meter to suck blood, and take a test strip and insert it into the machine; With a blood glucose meter, take a strip of test strip and hold it in your hand (fingers should not touch the test strip test area).

3.After taking out the test strip, cover the cover tube tightly, use a blood collection pen close to the fingertips, press the spring switch, and prick the fingertips with needles. Blood is best taken on both sides of the ring finger and abdomen, because it has abundant blood vessels and less distribution of nerve endings, which is not only painless but also bleeding sufficiently.

4.If it is a blood glucose meter that sucks blood, the blood is sucked into the special area of the test strip and waits for the result; If it is a blood glucose meter, put a plump drop of blood or wipe it on the test strip test area, insert the test strip into the machine and wait for the result. Do not add additional blood drops, as this will result in inaccurate test results.

Many people have a rapid blood glucose meter at home, but this instrument sometimes has errors, and because people's blood collection is not regular, it will also cause mistakes, some patients choose shallow blood collection needles because they are afraid of pain when collecting blood, and the result is that the blood flow is less, so they go to squeeze the needle to squeeze out the blood, so that the blood sugar measured is inaccurate. This is because when you squeeze the needle, fluid will flow out, and the blood sugar measurement will be low.

Use a blood glucose meter correctly to measure blood sugar.
