Does cbc test show diabetes?

My father has diabetes, and I'm concerned about my own risk. I just got a general blood test (CBC) done. Does a CBC test show diabetes, or do I need another specific test to check for it?

Bro, CBC won't show diabetes at all. I got it done last month thinking it covers everything, but my doctor told me I needed an HbA1c and fasting blood sugar test specifically for sugar tracking.

Please don't rely on just a CBC. I ignored my fatigue for months thinking my blood report was fine, but a proper HbA1c test later showed high diabetes. Get your fasting sugar checked properly by a doctor immediately.

Look, CBC is just for your blood cell count, it has nothing to do with sugar levels. If you suspect diabetes, go to a lab and ask for Fasting Blood Sugar and HbA1c. Simple.

My father always says that different tests are meant for different things, and he is right. A CBC cannot detect diabetes. It is best to visit your family doctor and get a prescription for a proper blood glucose test.

When I go for my yearly checkup at the hospital, they always run separate tests. CBC is strictly for blood count, while diabetes is detected via HbA1c and glucose tests. Ask your doctor clearly to prescribe the right package.

If you are planning your budget, don't waste money on just a CBC if you are worried about sugar. A CBC costs around 300 rupees but won't show diabetes. Better to buy a combined health package online for 800-1000 rupees that includes HbA1c and fasting sugar.
