"Routine semenology analysis" vs. "Rapid Centrifugal Analysis"

Hello there,

I hope someone can help me clear my doubts.
No luck trying for a baby for almost a year now. Recently my hubby has been classified Azoospermic with just one "routine semen analysis" report and that there is absolutely no sperm at all. Now that the doc says he has to undergo a testis biopsy without doing further tests like the US or a physical examination I am worried about the kind of testing they might've done!
On searching the internet I came across a site that says "Routine Semen Analysis" is different from "Rapid Centrifugal Analysis". Any light on this ?
I have an appointment with the GP tomorrow and I would like info on this.
Any help is appreciated.

Thanks.
