ACE & GM3+ Blood Glucose Test Strips are Biosensor test strips. They work on the amperometric principle.
Amperometric detection is based on measuring the oxidation or reduction of an electro active compound at a working electrode (i.e. sensor). A constant electrical potential is applied to the working electrode with respect to a second electrode called reference electrode. The applied potential is an electrochemical driving force that causes the oxidation or reduction reaction. This reaction generates a small amount of current which is measured by the Glucometer.
Applying the above principle to the ACE & GM3+ tets strips; the biological sensing element here is the enzyme, Glucose Oxidase, which is immobilized on the working electrode of the Gluco-strips. The glucometer is used to apply a constant potential to the test strip. When the blood sample is applied to the Gluco-strip, a redox reaction takes place. This is detected by the meter as a change in the current which is related to the quantity of sugar present in the sample. The ACE/ GM3+ Blood Glucose Meter shows this as your blood sugar reading.
Testing Normal Expected Readings
Sample Lab Values (mg/dl) GM3/GS Meter (mg/dl)
Venous Plasma Sample Capillary Blood
Fasting 60-120 0-128
Post Prandial <185 <200
Random <165 <200
For many people meter accuracy becomes an issue when they purchase a new meter and compare it to their old one, or go to the doctor to have a lab test and notice a seemingly large difference between the two test results. At first glance, you would expect all blood glucose monitors and lab equipment to give the same results. After all, they're measuring the same thing--the amount of glucose in a specific blood sample. Blood Glucose monitors and lab equipment are calibrated, or set, to measure blood glucose in different ways and will give different results.
Never compare your meter with another meter. Even two labs would not give identical readings.
GM3/ Digilyser Blood Gluco-monitor uses whole blood to measure glucose. Lab equipment uses only the plasma portion of blood; meaning that the red blood cells are removed before glucose is measured. Because of this difference in sample types, whole blood test results are approximately 12% lower than plasma test results
Since blood flows from capillaries to vein and the blood reaches vein only after the required glucose absorbed/ consumed by the cells surrounding the capillaries, the glucose is more in capillaries compared to vein. Many studies & trials reveal that the difference can range from 5-10%(fasting) to 20-26%(after meal containing carbohydrates). However in children the difference can vary more than 20% even in fasting. Other factors influence variation in blood glucose results include heamtocrit (red blood cell count), presence of alcohol in blood, other individual reasons, drug interactions etc.
ERRORS OF IMPRECISION:
These are the irregular or random errors. The commonest causes of scatter (imprecision) are:
ERRORS OF INACCURACY:
These are regular or consistent errors. All the results differ from the correct result by approximately the same value. The commonest causes are:
You should have your monitor checked periodically. Proper care and storage are also necessary. make sure the tubing is not twisted when the monitor is stored, and keep it away from heat. Periodically check the tubing for cracks and leaks.
Ask your doctor or nurse or our sales team to teach you how to use your blood pressure monitor correctly. Proper use of it will help you and your doctor achieve good results in controlling your blood pressure.
Since the digital monitor is automatic, it is the most popular blood-pressure measueing device. The blood pressure is easy to read, because the numbers are shown on a screen. Some electronic monitors have a paper printout that gives a record of the blood pressure reading.
The digital monitor is easier to use than the aneroid unit, it has a gauge and stethoscope that are one unit, and the numbers are easy to read on the display area. The device also has an error indicator. Furthermore, deflation is automatic. Inflation of the cuff is either automatic or manual, depending on the model. This blood pressure monitoring device is good for hearing-impaired patients, Since there is no need to listen to heart sounds through the stethoscope.
A disadvantage of the digital monitor is that an irregular heart rate changes the accuracy.
One advantage of this monitor is that it can easily be carried from one place to another. Also, the cuff for the device has a built-in stethoscope, so you don't need to buy a separate stethoscope. In addition, the aneroid monitor costs less than digital monitors do. Aneroid monitors range in price from about Rs.500-700.
The aneroid monitor also has some disadvantages. First, it is a complicated device that can easily be damaged and lose accuracy. The device is also difficult to use it it doesn't have the special festure - a metal ring - thatmakes it easier to put the cuff on. In addition, the rubber bulb that inflates the cuff may be difficult to squeeze. This monitor may not be appropriate for hearing-impaired people, because of the need to listen to heart sounds through the stethoscope.
To measure your blood pressure at home, you can use either an aneroid monitor or a digital monitor. The aneroid device has a dial gauge that is read by looking at a pointer. The cuff is inflated by hand by squeezing a rubber bulb. Digital monitors have either manual or automatic cuffs. The blood pressure reading flashes on a small screen. Choose the type of monitor that best suit your needs.
