WebAug 10, 2024 · If your serum osmolarity starts to climb too high, ADH will make you thirsty and signal your kidneys to retain water (by reducing urine output). This will help to “dilute” you, and will lower your osmolarity. The … WebThe calculated osmolality is then subtracted from the measured osmolality to provide the osmol gap, or the difference between these two values. If this gap falls within an acceptable range,(<10) then it is assumed that sodium, glucose, BUN are indeed the major dissolved ions and molecules in the serum.
