I too have raised ALP.(Alkaline Phosphatase).It is an enzyme in the blood which is concentrated in the liver.If it's elevated it can mean a lot of things eg. Some medications (Tamoxifen big time!)cause it,fatty liver and other liver diseases,other diseases and even a very fatty meal.If elevated,it is usually repeated and you should fast 10 hrs prior.My GP ordered me an abdominal ultrasound and it showed I have a fatty liver- possibly from being on Tamoxifen for 4 years. I'm about to have the blood test repeated. Tonya xx
