Read diabetes methods laboratory

Diabetes in the elderly and the secretion of insulin is not low, even higher than that of the clinical manifestations is not enough for the body to insulin, insulin resistance sensitive (Insulin Resistance, IR).

The following describes how to read a single approach to diabetes?

Read diabetes of laboratory methods:

Blood glucose measurement: diabetes is caused by a variety of causes to chronic high blood glucose metabolism disorder characterized by, so its diagnosis must rely on blood glucose checks.

But look great laboratory of blood sugar.

First of all, to distinguish this is extracting blood or fingertip blood.

Venous blood general hospital laboratories to detach after removal of red blood cells, plasma for automatic or semi-automatic determination of instrument. And fingertip blood is a drop of blood on the test strip to compact rapid determination of glucose meter. Plasma and blood glucose value may not be the same. Because very few of glucose in blood, containing red blood cells from whole blood glucose values than plasma glucose values to a low of about 12%. Current diabetes diagnosis criteria is fasting plasma glucose value is greater than or equal to 7-mol/l. If you have symptoms is a determination to diagnose, as silent then a few days after the test is still high or diagnosis. If the measuring capillary whole blood, the values corresponding to ≥ 6. 1-mol/l. You should then log a venous plasma of blood glucose values with a positive diagnosis.

Second, we must look at the time of measuring blood glucose.

General-8 hours after fasting for blood. But it can also be measured, postprandial blood glucose should start in 2 hours after meals. At this point because it is a meal, thus slightly higher diagnostic criteria, namely plasma glucose is greater than or equal to 11. 1-Moore/l to diagnosis. As for the capillary whole blood, and fasting. Because the absorption of glucose after dinner in the arteries, capillaries and later in various tissues and cells for metabolism and then back to venous blood glucose, venous blood sugar than artery. And capillary blood is close to the postprandial blood, so the capillary whole blood glucose is not like fasting as low blood sugar than venous plasma 12%, and is basically the same, that is greater than or equal to 11.1-Moore/l to diagnosis.

Of course, to our patients, not to care about these complex theory.

In order to follow up changes in their illnesses, buy a quality compact blood glucose meter, regular blood glucose testing (currently believe that after 2 hours logging than fasting measuring meaning large). Observation of the blood sugar level there is no clear increase or decrease, it will be able to explain the treatment appropriate or not. Because of falling too much to 3-mol/l, instead of hypoglycemia.

Glycated hemoglobin (HbAIC or AIC): erythrocyte hemoglobin in the blood, and glucose reaction saccharification and glycated hemoglobin (AIC).

AIC is generated, it is difficult to separate the original hemoglobin until the Red "end" (about 120 days) was destroyed after passed out. Normal blood sugar levels in normal General when the AIC is 4% to 6%. If blood glucose has been very high, or sometimes higher, will make the AIC. Determination of AIC values can therefore represent nearly 6 ~ 8-week average blood glucose value.

Read diabetes of laboratory testing methods including AIC's meaning and what's the difference between measuring blood sugar? logging blood glucose can only detect the moment of the blood sugar level, before a higher blood glucose might be, or it may be very low.

To test many times in order to understand the General blood sugar blood sugar levels. While the number of measurement, and time consuming and expensive. On a stable condition, a 2-month follow-up of patients at a time, measuring the AIC can more accurately reflect the condition. Therefore, more emphasis in recent years abroad for the determination of AIC.
