Glukoza po 75g glukozy - oznaczenie po 2h

Glucose after 75g of Glucose – 2-Hour Measurement

This test is performed using a blood sample to determine glucose levels 2 hours after consuming 75g of glucose. It is part of the oral glucose tolerance test (OGTT). It must be performed together with a fasting glucose measurement. Post-load glucose measurements are used to diagnose carbohydrate metabolism disorders (diabetes, neonatal hypoglycemia, idiopathic hypoglycemia). Indications include preventive screening, monitoring of at-risk patients, and testing in pregnant women. A known diagnosis of diabetes is a contraindication to the test.

If there is a positive history of hyperglycemia symptoms (increased thirst, frequent urination, unintentional weight loss), a capillary blood glucose test with a glucometer should be performed before administering the 75g of glucose to confirm the symptoms. If the test result is above 200 mg/dl, the glucose load should not be performed, and the patient should consult a physician.

The patient should arrive for the test by 9:00 AM with glucose purchased at a pharmacy.

• Blood is drawn into an EDTA tube, following standard procedures including skin disinfection, application of a tourniquet, and post-draw compression at the puncture site, which lasts several minutes.
• The blood draw takes approximately a few to several seconds. If the patient is not properly prepared, the test result may not be fully reliable.
• The blood sample should be collected in the morning hours.
• Required preparation several days before the test:
  • Do not consume alcohol for 2–3 days before the test.
  • Refrain from drinking coffee and tea for at least 12 hours prior to the test.
  • Avoid sources of stress as much as possible.
  On the day of the test:
  • The patient should be fasting – meaning no food intake for about 12 hours before the test.
  • In the morning, one glass of water may be consumed.
  • If possible, the blood sample should be collected before taking any morning medications, unless otherwise advised by the doctor.
  • Before the test, the patient should rest in a sitting position for 10–15 minutes.
  • Physical activity, even moderate (e.g., walking, climbing stairs), may alter lab test values, especially in diabetic patients.
  • The patient should arrive for the test by 9:30 AM.
  A known diagnosis of diabetes is a contraindication to this test.

• Test results are available within 3 business days.
• Results can be collected at the reception desk of any Medicover Centre.
• Online access to results is available via Medicover Online (a password must be obtained at the Medicover Centre reception).
