A fasting blood test is 12 hours isn’t it? It’s for my diabetes monitoring so hba1c and cholesterol included.

It is usually the information contained in your appointment letter, how long and if you need to fast.

Stay safe

Due to COVID there isn’t any paperwork anymore, you just have to take nhs number.
In the past it’s only ever said fasting, never how long,
Checked online and it said 12 hours but in my head I’ve got 16 from somewhere

12-14 hours water only is usually best for cholesterol testing.
For HbA1c it's irrelevant anyway.

My dr has always said I didn’t need to fast for hba1c. In fact at the start when I was worried about fasting due to the meds and then driving she told me to eat something like a sweet that wouldn’t aff3ct the cholesterol but also wouldn’t affect the hba1c.
 
My hba1c and cholesterol have been non-fasting

If I had not been fasting and ate a few hours before my appointment my blood glucose levels could be anywhere, up or down. If you didn't know, it is food (carbs) that triggers the bloods to first go high then low.
I was misdiagnosed in 2009, because of not fasting.

Hba1c is calculated over the previous 3 months so it doesn’t need to be fasting.
Cholesterol does. if you are doing a fasting blood glucose test then yes that needs to be fasting.
Hba1c I don’t think I’d a fasting blood glucose test.

Hi, unless I am in normal levels, the tests for me will be skewed by the food.
I'm am naturally in normal levels, eating food will give a different result than a non fasting test.
I have seen it.
Don't forget I'm not diabetic. I have the reaction to carbs.
The only reason why I have the Hba1c, is because it is a part of a full blood panel test.
But it is a record of how much it changes.
My Hba1c levels have been 37 for the past three years.
It is now 37, because I had mine done just a few weeks ago.
 
I fast for my blood tests, at least 10 hours after eating my last meal around in the evening. I do drink water as it does not make a differnece to hba1c of cholesterol tests.

I had a minor heart procedure (cardioversion) done last year and the fasting on that was no fluid after 6:00 an nothing eat after 12:00 am.

I like like the abolity to have black coffee upto 6:00 am. :)

I fast for at least twelve hours (but allow water and maybe black coffee) before my annual diabetic bloods. Won't impact HbAc1 but can influence lipid results (cholesterol levels).
 
Surgery and blood tests have different requirements. Coffee can effect cholesterol readings so best avoided. I used to live in Hervey Bay and visit Bundy quite often. How I wish I still did rather than back here in Blighty.
