You can find out the essential medical devices like nebulizers in every hospital, nursing home, and medical institutions. The function of a nebulizer is to warm a liquid or transform a liquid solution into a mist. This assists the patient to inhale the substance in a gaseous form and easily. Patients with critical conditions can’t intake liquids or medicines through the mouth, and a nebulizer ju...
Glucometers are reliable devices when it comes to monitoring of blood sugar levels. Comparing the results of glucometers and laboratory tests is pretty popular nowadays. It is due to the increased level of awareness in people about their body and its functioning. Most of the people reading this article might have done it, that’s how they landed up on this page!
When we talk about the results of both these procedures, these may vary slightly. However, the accuracy is the main thing that concerns people. Patients are worried about errors in reports that will indirectly affect their treatment. To know more about the difference in reports of laboratory investigations and glucose meter result, go through the points mentioned below:
Which one is more accurate?
Before talking about accuracy, it is necessary to know about the reason behind their recommendation. Doctors suggest the use of glucometer to patients with high blood sugar. It helps the patient in regular screening at home without the need to visit the hospital frequently. In this manner, you get a record of your blood sugar level.
If you find any suspicious fluctuation, you can immediately report to the doctor. On the other hand, periodical laboratory investigation is also necessary as it is more accurate than the glucometer readings. If you want to know the reason behind it, jump to the next point.
The site where the sample is taken from?
The next essential point is the site of puncture. You can either draw the blood from capillaries or directly from the veins. Venous blood mostly gives more accurate result in contrast to the capillary blood. It is because the sample volume is more when we draw venous blood from the arm. It is a more reliable indicator that gives you more accuracy. Thus, get yourself checked once a while with lab investigations.
Association with white coat hyperglycemia:
You might have heard of white coat hypertension! Similarly, there is an association of white coat hyperglycemia in the variations of results. When the patient visits a doctor’s clinic, he/she is more anxious and nervous. It can lead to alteration in the level of blood sugar, just like it happens in the case of hypertension. It can give false high or false low results depending upon your state of mind. However, when you test at home with a glucometer, you don’t have any association with stress. This point can also contribute to the difference in results of a glucometer and lab testing.
The mechanism of evaluation:
Depending upon the type of glucometer you own, it can either work by sensing or electric conversion. It is an entirely automated setting; you just have to take care of the blood amount. On the other hand, laboratory test requires various steps of processing the sample that requires both manual labor and automaticity. According to ISO, a deviation of 5 to 15 units is considered normal. As the glucometer is a screening test, you need to make sure if the digits fall under normal values or not.
Interpretation error is common:
Error in interpretation is very common in both household and hospital settings. It might be due to the machine or due to visual error.
Other factors governing the difference:
The environment, type of sample, size of sample, pollution, and the comfort level of patients are other factors that govern the difference between the results of these two.
We hope our readers are satisfied with these points. Thank-you!
