ALP hasn’t to do with the liver, instead it has to with the bile ducts (and other stuff). An elevated ALP suggests that your bile ducts are being damaged right now, but it doesnt show if your liver is getting damaged. It might be hard to grasp, the liver gets damaged when bile cannot flow out of it, which eventually happens with this disease. ALT is a measurment of liver damage, and because you have an elevated ALT it suggests that there is damage going on in the liver.
You can refere to ALP, ALT and AST as speedometers, it show how much damage is going on right now but it doesn’t show how much damage there is. But keep in mind that there is no maximum value for these test. Also keep in mind that you’re fine right now, since yoru Bilirubin is low (Bilirubin is a measurment of liver function).
