ANA ratio 8.3 . What does it mean?

[IsleofWight1]

I’ve googled this but just can’t figure it out.

Can anyone help to explain?

ANA ratio is the number of times a sample can be diluted and still give a positive result. They usually go 1:40 ( neg) 1;80,( weak pos) 1:160,1:320 ,1:640 etc .sorry don't understand 8.3 unless it's a typo 🤷‍♀️ .xx

It’s good of you to take the time to explain that to me, thank you. I’ll ask for clarification.

Not sure about the ratio of 8.3? 🧐

As @Spanielmadlady says, perhaps it’s a typing error?

This is worth a read about ANA blood test results:
