Glucose Post glucose (100 GMS)

This test measures your blood sugar levels after ingesting 100 grams of glucose. It helps evaluate your body's ability to metabolize glucose efficiently, providing insights into conditions like diabetes, hypoglycaemia, and other sugar metabolism disorders.

This test is done primarily:

• To diagnose diabetes by assessing your body's response to a glucose load
• To monitor gestational diabetes during pregnancy
• To evaluate insulin resistance in conditions like metabolic syndrome
• To diagnose reactive hypoglycaemia
• To assess carbohydrate intolerance

Your doctor will recommend this test:

• If you show symptoms of diabetes like excessive thirst or urination
• If you have risk factors for diabetes such as obesity or family history
• If you are pregnant to screen for gestational diabetes
• If you have signs of hypoglycaemia like dizziness or sweating
• If you are being evaluated for insulin resistance

• Abnormal results may indicate prediabetes, diabetes, insulin resistance, or hypoglycaemia.
• High levels suggest impaired glucose tolerance, while low levels could point towards reactive hypoglycaemia.

Consult your doctor for interpretation and further evaluation.

After consuming a glucose solution, blood samples are taken at intervals:

• You will fast overnight before the test.
• A blood sample is drawn for baseline glucose levels before ingesting the solution.
• You will drink a solution containing a high amount of glucose, followed by subsequent blood draws.

Before the test:

• Fast overnight.
• Avoid strenuous exercise or smoking before the test.
• Inform your doctor about any medications you are taking that could affect blood sugar levels.
• Follow any specific diet guidelines provided by your healthcare provider.

Reach out to your doctor for any specific requirements.

Other tests that may accompany this assessment include:

Haemoglobin A1c: Measures average blood sugar levels over the past 2 to 3 months.

Fasting Plasma Glucose: Assesses blood sugar levels after an overnight fast to diagnose diabetes or prediabetes.

Oral Glucose Tolerance Test: Evaluates how your body processes glucose after consuming a sugary solution.

Oral Glucose Tolerance Test or OGTT

Prediabetes is a health condition where blood sugar levels are higher than normal but not high enough for a diabetes diagnosis. It increases the risk of developing type 2 diabetes and heart disease if not managed effectively.
