Q for Jessica and Lolly

Hi, In your replies you use the abbreviations "EF" and "LEVF," which are foreign to me. What do these mean? Do these refer to your resting MUGA results? I take it that higher is better.... I need some "edducashun"! I've been on weekly herceptin and taxol since August and my MUGA results have been good, but I haven't asked for copies of the reports. Thanks!
