If you have a high sugar and/or a high carbohydrate diet, chances are that over a period of time, you may develop a high blood sugar condition. This means, if your diet regularly includes chocolates, cakes, canned fruits, pastries, cereal bars, puddings, donuts, ice creams, barbecue sauce, energy drinks and sodas, frozen desserts, large portions of french fries, rice, pasta, JELL-O, cookies, etc., then you are a likely candidate for developing hyperglycaemic conditions. Diabetes may also occur during the time of pregnancy and is termed as gestational diabetes.
Blood glucose tests are also ordered by the doctor to test for low levels of blood sugar or hypoglycemia.
Since high blood sugar levels that go undetected and untreated for long periods potentially involve increased risk of stroke, heart attack, kidney failure, and loss of vision, cognitive ability, and in extreme cases, amputation of limbs with circulation problems, it is important to find out if you have the condition so you can take corrective steps.
A doctor can prescribe a blood glucose test to search for the presence and level of a particular type of sugar in your blood. There are several types of blood glucose tests dependent on what the doctor suspects and wants to find out after hearing your symptoms and doing a basic physical examination. So, if you are experiencing increased thirst, fatigue, urination or blurred vision, and seeing infections healing over a long time, then the doctor may order a blood glusoce test for you. Here is a list of the types of blood glucose tests, when they are done and how they are conducted, along with the readings and values:
1. Oral Glucose Challenge Test (OGCT) For Pregnant Women:
This test checks the presence of gestational diabetes in pregnant women. The test is done between the 24th and 28th weeks of pregnancy. You will be asked to eat a balanced diet for three days before running the test and are to not smoke or drink alcohol for atl east eight hours before the test. The test may take up to four hours to conduct, during which time you can drink water only.
A blood sample is collected before administering a glucose load.
