1 of 3 things: Hi. If your TSH is 0.344, which is just slightly below the normal range, it could be: 1) normal, no thyroid disease (the normal range EXCLUDES 5% of normal values), 2) mildly hot (autonomously hyperfunctioning) nodule (s), or 3) your doctor checked it while it was heading down.
Rat urine, like human urine, can vary in different degrees. Normally, it will be a light yellow. If the rat is highly active, it will be taking in a lot of water. This may result in urine that is lighter or clear. This is absolutely normal in most circumstances. If the rat is drinking excessively and is not active, that could be a sign of trouble. Older or dehydrated rats may have darker urine.
Normal urine is clear and has a straw-yellow color. The color of the urine, however, can vary when foods of certain types are consumed or when certain medications are taken.ome substances that can change the color of the urine and potentially lead to darker urine are carotene, food colorings, beets, blackberries, laxatives, B complex vitamins, and drugs such as Pyridium.
