Answer: A finger stick glucose test is exactly what it is: it's a finger stick. So a little poke is make in the finger, and a little teeny, tiny drop of blood is withdrawn. And in that capillary blood we're able to determine blood sugar levels. And that's become a very good way to test blood sugars.
How do I check my blood sugar from my fingertip?
You’ll need these things to do the test:
- a blood testing meter
- a finger prick device
- some test strips
- a lancet (a very short, fine needle)
- a sharps bin, so you can throw the needles away safely.
Why is the finger used for checking blood sugar?
They used both a finger prick device and a forearm device to check their blood sugar levels at several points during the study. When the amount of sugar in the blood was rising or dropping rapidly, only the finger prick testing accurately caught these rapid changes.
Can you check your blood sugar without pricking your finger?
However, this method is still in the development stage and is very expensive. Another way that you can measure your blood sugar level without having to prick your finger is a wireless device that is worn around the wrist. This device uses an optical sensor to measure your blood glucose level by using flashes of light.
How to test your blood sugar without pricking your finger?
- Always wash your hands with soap and water before checking your glucose for a more accurate result. ...
- If inserting a sensor into your skin for a CGM, be sure to wash the area of skin with soap and water and allow it to dry first.
- Call your doctor if you experience skin irritation or discomfort from your sensor that lasts longer than a day.

What is the most accurate way to test blood sugar?
A1c test. Blood testing allows a doctor to determine the levels of blood sugar in the body. The A1C test is one of the most common because its results estimate blood sugar levels over time, and you don't have to fast before the test. The A1C test is also known as the glycated hemoglobin test.
What is the most reliable indicator of blood sugar status?
Fasting plasma glucose test For the most reliable results, your doctor will give you the test in the morning after you have fasted for at least 8 hours. Fasting means having nothing to eat or drink except sips of water.
What can cause a false high glucose reading?
High uric acid and low hematocrit values have been suggested to cause falsely high BG readings, thereby resulting in inappropriate therapeutic decisions.

A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours means you have diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) means you have prediabetes.
What is blood glucose monitoring?
Blood glucose monitoring is a way of testing the concentration of glucose in the blood (glycemia). Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, on the finger) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
How does glucose monitoring help with diabetes?
Since its introduction three decades ago, self-monitoring of blood glucose (SMBG) using finger-stick blood samples, test strips, and portable meters has aided diabetes management, principally by enabling patients—particularly those treated with insulin—to become full partners along with health professionals in striving for excellent glycemic control. Over time the use of glucose meters has become easier and faster with smaller and smaller blood samples yielding results in a matter of seconds. For this reason, glucose meters are now increasingly used in hospital wards, intensive care units, and other facilities such as dialysis units and infusion centers to provide point-of-care results that would take much longer through routine laboratory channels. This technology has largely taken the guess work out of diabetes management. Without such technology, intensive glucose control such as that achieved in the Diabetes Control and Complications Trial may not have been demonstrated to prevent or decrease microvascular complications; insulin pump therapy would not really be practical; and hypoglycemia would remain an even greater source of anxiety for patients and their families than it already is. We have come to rely so much on finger-stick glucose that it is easy to forget its limitations. In considering this we will discuss accuracy, specificity, and, in light of those, inappropriate usage. Accuracy Although there is no universally binding standard, guidelines issued by the International Organization for Standardization (ISO) are widely acknowledged. ISO guideline 15197 suggests that for glucose levels <75 mg/dl, a meter should read within 15 mg/dl of the reference sample, and for levels ≥75 mg/dl, the reading should be within 20%.

Is there a universally binding standard for glucose levels?
Go to: Accuracy Although there is no universally binding standard, guidelines issued by the International Organization for Standardization (ISO) are widely acknowledged. ISO guideline 15197 suggests that for glucose levels <75 mg/dl, a meter should read within 15 mg/dl of the reference sample, and for levels ≥75 mg/dl, the reading should be within 20%. A meter also should be able to meet these targets in at least 95% of the samples tested (1). Several examples serve to illustrate the implications of this degree of imprecision. Assuming a meter does indeed meet the ISO guideline, then a true glucose level of 55 mg/dl could in fact yield an SMBG reading of as low as 40 or as high as 70 mg/dl, and occasionally (1 time in 20) a reading beyond those limits. While a reading of 40 mg/dl is likely to prompt corrective action that could be quite appropriate for a true value of 55 mg/dl, the same is not likely to be the case for a reading of 70 mg/dl, which in many instances will be regarded by the patient as reassuring, if not cause for congratulation. This could be particularly inappropriate—and hazardous—in a patient with hypoglycemia unawareness whose glucose of 55 mg/dl is “on the way down” rather than stable or increasing. At the other end of the spectrum, a true value of 350 mg/dl might register as low as 280 or as high as 360 mg/dl. Because all of these values are obviously much higher than desirable in any circumstance, it could be argued that this is of no consequence because they all should lead to glucose-lowering action. But this is true only up to a point since in these days of insulin infusion algorithms aimed at achieving excellent glycemic control in intensive care situations and the use of premeal corrective insulin doses in patients using multiple dos Continue reading >>

What Is A Normal Result For Finger Prick Test?
Diabetes Forum The Global Diabetes Community Find support, ask questions and share your experiences. Join the community What is a normal result for finger prick test? Hi can anyone help please. I just had a finger prick blood test at the hosp last fri and the nurse said it was "10". Can someone tell me what this means on the scale of diabetic results? Thanks Hi can anyone help please. I just had a finger prick blood test at the hosp last fri and the nurse said it was "10". Can someone tell me what this means on the scale of diabetic results? Thanks A sample of blood taken at any time can be a useful test if diabetes is suspected. A level of 11.1 mmol/L or more in the blood sample indicates that you have diabetes. A fasting blood glucose test may be done to confirm the diagnosis. A glucose level below 11.1 mmol/L on a random blood sample does not rule out diabetes. A blood test taken in the morning before you eat anything is a more accurate test. Do not eat or drink anything except water for 8-10 hours before a fasting blood glucose test. A level of 7.0 mmol/L or more indicates that you have diabetes. If you have no symptoms of diabetes but the blood test shows a glucose level of 7.0 mmol/L or more then the blood test must be repeated to confirm you have diabetes. If you do have symptoms and the blood test shows a glucose level of 7.0 mmol/L or more then the test does not need to be repeated I wonder if the OP wondered to know if 10 was low, normal, or high etc.? BG numbers from a finger prick test show how much glucose there is in the bloodstream at that particular moment. Depending on how long it was since you last ate and what you did eat, your activity levels etc. this number will vary throughout the 24 hours. The number is only a guide really as it can vary perpetu Continue reading >>

What Are The Ideal Levels Of Blood Sugar?
Blood sugar charts also help those with diabetes assess and self-monitor blood sugar test results. What is a blood sugar chart? Blood sugar charts act as a reference guide for blood sugar test results. As such, blood sugar charts are important tools for diabetes management. Most diabetes treatment plans involve keeping blood sugar levels as close to normal or target goals as possible. This requires frequent at-home and doctor-ordered testing, along with an understanding of how results compare to target levels. To help interpret and assess blood sugar results, the charts outline normal and abnormal blood sugar levels for those with and without diabetes. In the United States, blood sugar charts typically report sugar levels in milligrams per deciliter (mg/dL). In the United Kingdom and many other countries, blood sugar is reported in millimoles per liter (mmol/L). A1C blood sugar recommendations are frequently included in blood sugar charts. A1C results are often described as both a percentage and an average blood sugar level in mg/dL. An A1C test measures the average sugar levels over a 3-month period, which gives a wider insight into a person's overall management of their blood sugar levels. Blood sugar chart guidelines Appropriate blood sugar levels vary throughout the day and from person to person. Blood sugars are often lowest before breakfast and in the lead up to meals. Blood sugars are often highest in the hours following meals. People with diabetes will often have higher blood sugar targets or acceptable ranges than those without the condition. These Continue reading >>

How many people have diabetes?
According to the American Diabetes Association, 25.8 million Americans are diabetic. Another 7 million are diabetic but have not been diagnosed. And, 79 million are prediabetic, meaning they are at high risk for developing diabetes at some point in their lives. Knowing the normal glucose range and what your numbers are is the first step in protecting yourself from diabetes. Video of the Day A simple finger stick test using a very small drop of blood is all that is needed to check your glucose level. This should be part of your yearly physical, even if you have never had diabetes. Early screening allows early treatment. The most accurate measurement is a fasting blood sugar, preferably early in the morning before you've had anything to eat or drink. Your health-care provider will let you know how you should prepare for the test. What the Numbers Mean A fasting blood sugar of 99 mg/dL or less is considered within the normal range. A person is prediabetic if fasting blood sugar is between 100 to 125 mg/dL. Diabetes is diagnosed at 126 mg/dL or greater. It's important to note that one high blood sugar does not automatically make you diabetic. Instead, your health-care provider will likely order follow-up glucose testing over the next few weeks to determine your normal range. What if My Numbers are Elevated? If your numbers fall into the range of diabetes or prediabetes after follow-up testing, your health-care provider will prescribe a plan of treatment. In the early stages of diabetes, if your glucose is only mildly elevated, you may be able to control it with diet and physical exercise on a regular basis. Being more aware of what you eat is an important step to controlling diabetes. You may find a food log helpful to pinpoint areas in which you can make better choices. In Continue reading >>
