WebA drop in low plasma osmolarity causes the osmoreceptors to increase in size since water enters those cells by osmosis. The osmoreceptors then send fewer impulses to the hypothalamus causing less ADH to be released. Less water is reabsorbed in the kidney to lower the blood water potential. This results in the production of very dilute urine. WebWhy the Test is Performed. This test helps check your body's water balance.
