Thankyou for your response Terri. Just one last question from me…
1. I read that with the ELISA test, 92% of positive results are correct and 98% of negative results are correct.
And then with Western Blot 94% positive results are correct and 99% of negative results are correct.
Do you agree with this? Therefore the western blot would only be 1% more accurate in giving me a true negative?
2. Does a low negative index number mean it more likely to be a true negative than a higer negative index number?
Thanks again for your patience and advice!
