Glucose Tolerance Test Powder 75.75 g – Diagnostic Oral Glucose Powder

Glucose Tolerance Test Powder 75.75 g – Diagnostic Oral Glucose Powder

Glucose Tolerance Test Powder 75.75 g is a pre‑measured diagnostic glucose powder designed specifically for use in the Oral Glucose Tolerance Test (OGTT) — a widely accepted medical procedure that evaluates how effectively the body processes glucose, an essential carbohydrate. The powder’s precise dosing ensures that each 75.75 g sachet delivers an accurate glucose load for diagnostic testing of diabetes, prediabetes, impaired glucose tolerance and related metabolic disorders.

Each package contains 75 g of glucose powder along with stabilizing excipients such as citric acid monohydrate. The formulation is white, odorless and easily soluble in water, making it suitable for preparing the glucose solution used during laboratory testing.

The OGTT is a standard clinical procedure used by healthcare professionals to determine whether an individual’s body can properly regulate blood glucose levels after a controlled glucose stimulus. It is especially valuable when fasting glucose tests alone are not sufficient to make a diagnosis or when screening for conditions such as type 2 diabetes, gestational diabetes, prediabetes and other glucose metabolism abnormalities.

Why Glucose Tolerance Testing Is Performed

The Oral Glucose Tolerance Test (OGTT) helps assess an individual’s glucose regulation by measuring blood sugar levels before and after consuming a defined glucose load:

• Individuals fast overnight for at least 8–12 hours before the test begins.

• A baseline fasting blood glucose level is first measured.

• The glucose powder is then dissolved in water and consumed within a short period (usually within 5 minutes).

• After drinking the solution, blood glucose levels are measured at defined intervals (typically 1 hour and 2 hours after ingestion) to observe how the body responds to the glucose load.

Values after a 2‑hour glucose load help clinicians distinguish between normal glucose tolerance, impaired glucose tolerance (prediabetes) and diabetes mellitus. For example, a 2‑hour post‑load blood glucose of ≥ 11.1 mmol/L (200 mg/dL) usually indicates diabetes, while levels between 7.8 mmol/L (140 mg/dL) and 11.0 mmol/L (199 mg/dL) indicate impaired glucose tolerance.

Screening for gestational diabetes — a form of glucose intolerance during pregnancy — also typically uses a 75 g glucose load, although specific protocols and plasma sampling schedules are guided by clinical standards.

Key Benefits of Glucose Tolerance Test Powder

1. Standardized Diagnostic Dose
Each unit contains a controlled dose of 75.75 g of glucose powder, matching the amount recommended by international health guidelines for adult OGTT procedures.

2. Simple Preparation
The powder is designed to dissolve easily in water, creating a consistent glucose solution for immediate use in laboratory testing.

3. Clear Evaluation of Glucose Metabolism
The OGTT provides more detailed insight than fasting glucose alone, enabling clinicians to detect early or borderline conditions related to glucose handling, including prediabetes and insulin resistance.

4. Valuable for Clinical Screening
This test is especially useful when other measures — such as fasting glucose or HbA1c — don’t fully explain a patient’s symptoms or risk factors but a comprehensive glucose response evaluation is needed.

5. Application in Pregnancy
In prenatal care, the 75 g glucose tolerance test is routinely used to screen for gestational diabetes, helping manage maternal and fetal health during pregnancy.

How to Prepare and Use the Powder

Glucose tolerance testing must only be conducted under medical supervision as part of a clinical assessment. Typical steps include:

1. Fasting: The patient fasts overnight (at least 8–12 hours) prior to testing, consuming only water and refraining from food or other specified substances.

2. Baseline Measurement: A fasting blood glucose sample is taken before consuming the glucose solution.

3. Preparation: Dissolve the entire 75.75 g pack of powder in the recommended amount of water (usually about 250–300 ml).

4. Consumption: The glucose solution is consumed quickly (often within 5 minutes).

5. Follow‑Up Sampling: Blood glucose samples are collected typically 1 hour and 2 hours after ingestion to assess how the body handles the glucose load.

Results are interpreted by a healthcare professional to classify glucose tolerance status and plan appropriate clinical care or lifestyle recommendations.

Important Preparations & Precautions

To ensure accurate and reliable results:

• Avoid smoking, heavy physical activity, and certain medications before the test as they can affect glucose levels.

• Test should generally not be performed during periods of acute illness, recent major surgery, or other significant physiological stress, as these can alter glucose response.

• Check with a healthcare provider regarding medication use, as substances such as corticosteroids, caffeine, certain diuretics and other drugs can influence glucose measurements.

Test results must always be interpreted by a qualified clinician in the context of individual health, medical history and additional laboratory findings.

Storage and Handling

Store the sugar powder in a cool, dry place below 25 °C, away from moisture, strong odors or contaminants. Keep out of reach of children and do not use the powder beyond the expiration date printed on the pack.
