The highest concentration of solutes in tubular fluid is found in the deep medullary regions of the kidney, known as the renal medulla. This high solute concentration is necessary for the kidneys to concentrate urine and maintain water balance in the body.
The lowest concentration of nitrogen can be found in the urine when it is first produced. As it accumulates in the bladder, so does the overall concentration of nitrogen.

The highest concentration of THC is typically found in the flowering buds of the cannabis plant. Specifically, the trichomes on the flowers are where the highest concentration of THC is located.
If your urine is too diluted, the test may show a false -. It's best to test with your first morning urine to ensure it is at it's highest concentration.

The highest carbon dioxide concentration in the body will be found in the tissues and cells, where it is produced as a byproduct of cellular metabolism. This carbon dioxide is then transported via the bloodstream to the lungs for exhalation.
The normal glucose concentration in urine ranges from 0 to 15 mg/dL. The glucose concentration in urine becomes zero when no glucose has spilled over into the urine.
ADH, or antidiuretic hormone, increases water reabsorption in the kidneys, leading to more concentrated urine. As water is reabsorbed, the concentration of solutes in the urine, including potassium, increases. Therefore, ADH indirectly affects the concentration of potassium in urine by influencing the overall concentration of solutes.
