Blood Sugar 1/2 Hour

Blood sugar is also known as Glucose, is an important sugar found in the blood. In diabetic conditions glucose level of the blood varies (hypoglycemia/hyperglycemia) may be altered leading to extreme pathological states leading to life-threatening conditions and hence this causes serious health issues (contributes to morbidity and mortality). A post-prandial blood sugar test evaluates the blood sugar level after the meal to check the insulin-related health issues.

Why Blood Sugar – Half an Hour (½hr) Test?  


Glucose is the primary energy source of the body’s cells (including the brain) and hence the relatively constant level of glucose must be maintained in the blood. Normally after a meal, blood glucose rises and so the hormone insulin (secreted from the pancreas), helps transport glucose to the body’s cells where it is used as a source of energy (ATP produced by glycolysis and Kreb’s cycle). Diabetes is a disease resulting from an imbalance between glucose and insulin. Type-1 diabetes results when body is not able to produce insulin to control blood glucose levels (auto-antibodies that destroy the beta cells of the pancreas) and type-2 diabetes results from a combination of insulin resistance (reduced sensitivity of insulin against blood glucose compared to normal person’s response) and relative decline in insulin production. Other types of diabetes include gestational diabetes (the condition restores back to normal after pregnancy period), juvenile diabetes etc. Test result of glucose tolerance test is represented as a blood glucose chart shows a person’s blood sugar levels – including before (fasting) and after meals (post-prandial). It helps a person with glucose management to maintain within normal range or in the prognosis of patients with diabetes treatment plans. OGTT is gold standard for diabetes type 2 and also useful in pre-diabetes, gestational diabetes, insulin resistance, impaired beta cell function, disorders of carbohydrate metabolism (carbohydrate metabolism), and risk of developing diabetes prior to pregnancy or in high risk cases of developing diabetes during pregnancies etc. 

Blood Sugar – Half an Hour (½hr) Test is a part of Oral Glucose Tolerance Test (OGTT). It identifies the abnormalities in the way the patient’s body handles glucose after a test dose of glucose (75 / 100 Grams) is administered. Patient is fasted for about eight hours before the test or preferably fasted overnight and the test schedule is performed in the early morning hours. Blood specimen is drawn to monitor the glucose levels in different time intervals (30 minutes/ ½ an hour, 1 hour, 1 ½ Hour’s, 2 hours, 2 ½ and 3 hours, etc). A graph is plotted against the time v/s blood glucose levels as the body system responds to the administered glucose load in OGTT. The test result is interpreted accordingly and diagnosis is made in the case of diabetic patients (impaired fasting glucose, impaired glucose tolerance, etc) with suitable treatment modalities. Causes are family history, obesity, high blood pressure, sedentary lifestyle, junk foods, old age, etc. Signs and symptoms are hyperglycemia, polyuria, polydipsia, and polyphagia, etc. Complications of untreated diabetes include morbidity and mortality rate (life expectancy), risk factor for cardiovascular diseases, metabolic syndrome, obesity, polycystic ovarian disease (PCOD), damages in the thin and fine small arteries such as in the eyes, end-organ damages eg. eyes, kidneys, blood vessels, brain and heart, stress, foot problems, and other illnesses, etc. False-positive test results can arise in smokers, consuming coffee (caffeine-based products), and patients on certain medications like corticosteroids, diuretics (water pills), anti-depressants, etc. Other tests include Hb-A1c to monitor prognosis in patient’s compliance during diabetes treatment.
