English Language requirement with a PhD degree from the UK

My spouse is a UK citizen. I am applying for a spouse visa. I have a masters as well as a PhD degree from a top school in the UK. Will it count towards the English language requirement? If yes, can I just submit copies of my degrees or shall I also have to get some sort of certificate from the UK NARIC?

Also, in the past I had applied for the same spouse visa. I was in the UK then and had taken an English language test from EMD on Feb 16, 2011. Is it still valid? I do not have much time now and taking an English language test will delay the visa application by at least two weeks. Is there any quick test for somebody living in the USA?

Will appreciate a quick answer. Many thanks.
