GTT (3 and 4 Samples) 100gm Glucose Orally Test Cost & Procedure

An oral glucose tolerance test (OGTT) is a diagnostic procedure carried out in a lab to ascertain the state of impaired glucose tolerance, prediabetes, and diabetes, how the body metabolises glucose and how glucose is transported from the blood and to the body tissues.

Patients with cardiovascular problems can also be screened with the OGTT for diabetes. In nations like India, the OGTT is a crucial technique for diagnosing gestational diabetes.

This is because this test is reasonably priced. Moreover, the WHO has advocated for a universal OGTT screening for gestational diabetes due to the absence of medical infrastructure in rural regions. Following the discovery of pregnancy, this is done initially with a fasting blood glucose test and an OGTT during the last 24-28 weeks of gestation. An OGTT is furthermore performed in the 32nd week of pregnancy in circumstances where there is a high risk of gestational diabetes.

Test's Objective (Indications):

• To validate the pregnancy-related diabetes diagnosis
• Diabetes mellitus is diagnosed using it
• It is additionally employed to assess hypoglycemia.
• Patient with diabetes in the family.
• Patients who are obese.
• Patients who frequently contract H/O infection.
• Wound healing was slowed down in H/O patients.
• Who has had stillbirths or delivered obese children
• Individuals with sporadic H/O glycosuria or hyperglycemia when pregnant, following a myocardial infarction, surgery, or stress.

Procedure for an oral glucose tolerance test:

The American Diabetes Association (ADA), WHO, NDDG, CDA, and other organisations have adopted different oral glucose tolerance test protocols.

While the ADA recommends screening for high-risk people, countries like India require universal screening because pregnant women have a higher chance of developing gestational diabetes. It is a requirement for all surgeries that the patient fast for at least eight hours, during which only water may be consumed. However, some individuals are not good candidates for an oral glucose tolerance test. They consist of:

Individuals whose fasting blood glucose level is more significant than 126 mg/dL

Individuals who already have diabetic symptoms like polyuria and polydipsia

individuals with ketonuria (presence of ketones in urine)

Moreover, OGTT is not advised for those who have had surgery, have experienced trauma, an infection, or even significant psychological stress.

The preparation of a glucose solution for the administration of glucose involves combining glucose and warm water. This is because warm water helps glucose break down more quickly. Nonetheless, the cold glucose solution tastes good. The criteria for identifying gestational diabetes

• The glucose level at fasting time is greater than 95 mg/dL
• A 1-hour level exceeds 180 mg/dL
• The 2-hour level exceeds 155 mg/dL
• The 3 hours- is more significant than 140 mg/dL
