But if the liver is inflamed or injured, ALT is released into the bloodstream. Measuring blood levels of ALT can give doctors important information about the liver and whether a disease, inflammation, drug, or other problem is affecting it.
Potatoes are ready for harvest when the foliage first starts to die and turn yellow. Early (new) potatoes can be lifted earlier (no earlier than June ) to get the very tastiest potatoes. In this case, harvest them about a week after the potato plant flowers first appear. New potatoes only produce a couple of handfuls of potatoes per plant, so dig up the whole plant. After flowering.
You need to cover the plant with more earth, about 1/2 way up the plant, then when the plant doubles in size do that again. Then in the late fall, you can start to harvest potatoes, after a light frost, or you can wait until the green tops die off completely and get mature potatoes. I grow them in Massachusetts, but I am guessing the same applies else where.
