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.
The first of the physical properties to be considered is color. The color of urine often varies with its concentration and is most often reported as some shade of yellow (straw, light yellow, yellow, dark yellow, and amber). Normal urine can be found in any of these colors, with the exception of the âamberâ color.
