A glucometer is a medical implement whose main use is to approximate the concentration of glucose in the blood of the user. Users of this product are typically patients who have type 1 or type 2 diabetes or hypoglycemia. These users have to manage their ailments by monitoring their blood sugar levels several times a day with the goal of keeping them close to normal levels.

Individuals can use these tools to measure blood sugar levels by pricking some blood from their fingers and then putting it on a disposable test strip. Then, they feed the test strip to the meter which uses the sample to calculate the sugar level. In a handful of minutes, glucose meters display results in milligrams per deciliter or millimoles per liter.

Monitoring blood glucose in this manner is pricey especially for persons who have type 1 diabetes. These persons need to test their blood up to ten times every day. The cost arises from the fact that each test strip may be used for one time only, and each strip costs anywhere from a 50 cents to a few dollars. There are even glucometer manufacturers who hand out the machine for free in order to secure sales of test strips. However, meters that use discs that are reusable are also available in the market.

People looking for their own glucometer models must remember some factors that vary from model to model. The physical qualities of glucometers include size, display, and memory or clock. The average size of a glucose meter is palm sized, while some models run larger or smaller.

Glucose meters also diverge in the units of measure in which they show results. The ones used in the U. S., France, Japan, Israel, and India generally show the reading in mg/dl. Those used in Canada, Australia, China and the UK show the result in mmol/l. For those who want to convert mmol/l to mg/dl, simply multiply the result by eighteen. To convert mg/dl to mmol/l, divide the result by eighteen. In general, only German medical practitioners do work in both measurement units.

One other quality that changes from variant to variant is the clock, or memory. This is the feature that shows the present time and date. It is also the one that hoards past results. The more memory there is, the more results can be hoarded. The memory makes it possible for individuals to view trends and patterns in their blood sugar concentrations.

Since these machines are generally used to keep track of medical conditions, their accuracy is a very important factor. Based on the International Organization for Standardization rules, glucometers must give results that are accurate to within twenty percent of lab standard 95 percent of the time. To reach such accuracy levels, the ideal machine must not be vulnerable to factors like temperature and humidity, amount and quality of the blood sample, and the presence of other things in the blood.

In the future, it may be possible to have a noninvasive glucometer that will allow glucose level monitoring continuously. For now, consumers will have to make do with devices that test their blood samples. In choosing blood glucose meters, people need to check out how expensive the test strips or discs are, its memory strength, size, and accuracy.
