Blood glucose is estimated basically in two different ways:
1. Laboratory tests performed by professional medical care suppliers
2. Personal blood glucose meters
How are these tests unique?
Personal meters measure your blood glucose using an example from your fingertip (or substitute site), and afterward break down the entire blood, including red blood cells what not.
In a lab test performed by clinical staff, the example is normally drawn from a vein in your arm and handled to eliminate red blood cells, so only the plasma is tested.
Practically all home glucose meters figure the distinction of using an entire blood test while providing a test result that is considered plasma same.
Which is more precise?
Lab tests by and large demonstrate a more significant level of exactness than personal blood glucose meters, yet even these machines can have a slight margin of blunder. Blood glucose meter test results are not precise measures, but rather they’re intended to give you exact readings for day to day treatment decisions when you’re not at a specialist’s office.
Without going into detail on how your circulatory framework functions, there are different variables that might make the two readings shift somewhat, yet regularly an outcome from a meter that is within 15-20% of your lab reading is considered precise. Thus, assuming your lab result says that your blood glucose is 100 mg/dL, your meter could report your outcomes as 85 mg/dL or 115 mg/dL despite everything being considered exact.

8 Factors That Can Affect Glucose Meter Accuracy
Test Strips
At the point when you utilize a test strip, the glucose in your blood interacts with chemicals on the strip. This deliveries electrons, creating an electrical flow. The meter then, at that point, converts that into a concentration of glucose to give you a reading.
Since this cycle is so confounded, your test strips can be extremely delicate to factors. Inaccurate outcomes can emerge out of test strips that:
• Are harmed or lapsed
• Are impacted by intensity or dampness
• Need more blood applied
• Are not intended for your meter
• Have contaminants (oil, lotion, food) on the example region
Exactness Tip: You ought to continuously keep your test strips in their container, put away at the temperature determined by the producer. Test strip plans might differ, so it’s vital to comprehend where the blood test ought to be applied to try not to test mistakes or inaccurate outcomes. Additionally, ensure that you’re using test strips that poor person lapsed and are made explicitly for your meter model.
Environmental Conditions
The science of your test strips, as well as your own bloodstream and composition, can be impacted by the conditions of your environment.
A functioning component in the test strip science, called a chemical, can be delicate to temperature and stickiness conditions. Temperature and stickiness limits can make the chemical movement reduction and influence the precision of results.
Your body additionally responds distinctively at various temperatures. High temperatures can make it more straightforward for you to become got dried out and concentrate (hoist) glucose levels, while low temperatures might influence circulation and lower blood stream to testing sites.
An examinations have shown gadgets to over or under gauge glucose while testing at high heights. Assuming that this is of concern, confirm the elevation rating for your gadget.
Substances on Your Skin
Anything you contact or set on your skin can wind up in your blood test and afterward on your test strip. Since numerous ongoing meters use a miniature measured blood test, simply touching something that contains sugar and not washing your hands can influence your readings. In the event that you as of late cleaned up yet didn’t dry them totally, the water left on your fingers can significantly affect the example, also.
Amount of Blood in Your Test Strip
It’s feasible to have excessively or insufficient blood in the test strip test region, which can prompt inaccurate outcomes or a blunder reading.
Exactness Tip: Your meter ought to express the necessary blood test size, as 0.5 microliters, so you have an understanding of how much blood is required for testing. Abstain from squeezing straight around the speared region while forming a blood drop. You can likewise explore different avenues regarding different size lancets to find one that delivers the amount you want.
Testing Site Location
Due to the physiological contrasts in the circulation of certain regions of your body, test results from substitute sites (like your lower arms, calf, or thigh) are often less exact than testing with your fingertip. This is because of the recurrence with which new blood flows to each piece of the body. Assuming you have as of late eaten, worked out, or taken medication that could bring down your glucose, these progressions may not be recognized as fast in substitute sites as in the fingertip.
Exactness Tip: Check the instructions for your meter to comprehend what substitute site testing might mean for your outcomes.
Incorrect Coding
A meter that requires coding implies you’ll have to input a code printed on each test strip vial in request to align it before use. On the off chance that the code doesn’t match accurately, it could prompt inaccurate readings.
Exactness Tip: Many “No Code” meters are accessible now, which allows you to stay away from this step. However, assuming that you have a meter that actually requires coding, ensure you input the code accurately to keep away from inaccuracies.
