what does high blood sugar mean in a blood test

High blood sugar, also known as hyperglycemia, indicates that the level of glucose in your blood is higher than the normal range. This can be detected through blood tests such as:

• Fasting Blood Glucose Test: Normal levels are below 100 mg/dL. Levels between 100–125 mg/dL indicate prediabetes, and 126 mg/dL or higher suggest diabetes.
• A1C Test: This measures your average blood sugar over the past 2–3 months. Normal A1C is below 5.7%. Levels between 5.7–6.4% indicate prediabetes, and 6.5% or higher suggest diabetes.

High blood sugar can be a sign of diabetes or prediabetes, and it may also occur due to stress, illness, or certain medications. If left unmanaged, it can lead to serious health complications such as heart disease, kidney damage, and nerve problems.

If your blood test shows high blood sugar, consult your healthcare provider for further evaluation and management.
