Q
Why is my blood glucose level measured with the meter
different from the one measured in the hospitals?
A
Blood glucose level varies all the time. It
also differs according to the blood sampling
point.
Different time of measurement
Different sampling point
Even shortly after returning from your hospital examination, you may find that
the blood glucose level measured at home, is different from the one conducted
at the hospital. The reason is that the body uses glucose according to its energy
requirements. The glucose is replenished when carbohydrates are taken into the
blood stream after eating.
Blood is supplied from the heart through the arteries to capillary blood vessels.
After supplying nutrition, including glucose, to the body’s tissues, blood returns to
the heart through the veins. Capillary blood therefore contains more glucose than
venous blood. In hospital, blood samples are normally taken from a vein in the arm,
whereas at home the capillary vessels of the finger are used as the sampling point
with Test TIP. Therefore the hospital’s test value of the blood samples from the arm
will be different from the value of the blood from the finger tip.
