When should Glukose be retested?

The optimal timing for retesting glucose depends on the purpose. For diabetes management, self-monitoring is typically recommended before meals and/or 2 h postprandial, depending on therapy. For diagnosing prediabetes or diabetes, fasting plasma glucose (after 8–12 h) or HbA1c (every 3–6 months) are standard. An oral glucose tolerance test (OGTT) is used for specific indications. In healthy individuals without risk factors, a single measurement during an annual check-up is sufficient. Important: single home-test values are not diagnostic and should be confirmed by venous lab measurement. Evidence is based on clinical guidelines (e.g., DDG, ADA) and practice. Caveat: factors like time of day, stress, illness, or medications can affect results.
