I am a long standing patient of Dr. Klimas and live in South Florida. Her waiting list is close to 9 months for new patients, although the University of Miami has recently hired an additional CFS physician to work with Nancy and they will likely be able to add patient volume to the practice. At my last appointment, Klimas advocated waiting until there was a more standardized test for XMRV, which she thought would be available in the next year.
Nancy does perform some expensive immunological testing to evaluate viral titers, natural killer cell activity, cytokine expression, etc. I can't speak for all of her treatment plans but she has a lot of tricks up her sleeve, including immune modulators, anti-viral drugs, sleep drugs, etc. I've had a lot of improvement with her protocols over a period of time. You will want to have a primary care physician working with you and her who can monitor you on a regular basis. She is not easily accessible between visits and I typically see her two to three times each year.
