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 normal color of urine can range from a translucent yellow to amber. It is a sterile liquid that is expelled from the body and is a product of cellular metabolism. The appearance of your urine can be affected by certain foods you eat, beverages you drink and diseases that you may be afflicted by. The yellow to amber color that normal urine has is due to a pigment called urochrome. When your urine is darker (amber), this usually is a sign you arenât getting enough fluids.
