What each test shows
Fasting sugar measures blood glucose after fasting, while post-meal sugar reflects glucose after food. HbA1c gives a broader view of average sugar control over recent weeks and is commonly used for diabetes monitoring.
When doctors may advise these tests
Tests may be advised for frequent urination, excess thirst, fatigue, weight changes, family history, high BMI, pregnancy screening, diabetes treatment monitoring or preventive checkups after 35 to 40 years.
Suggested diabetes package
A practical diabetes screening set may include fasting sugar, post-prandial sugar, HbA1c, urine routine, kidney function and lipid profile. ECG or eye/kidney evaluation may be added based on physician advice.
Preparation
Fasting blood sugar usually requires overnight fasting. HbA1c generally does not require fasting, but follow your doctor’s instructions if multiple tests are being done together.
Frequently asked questions
HbA1c is useful, but doctors may combine it with fasting or post-meal sugar depending on symptoms and treatment status.
Home collection may be available for blood tests. Confirm fasting requirements before collection.
