Osmolality is the measurement of concentration of particles in a solution, such as electrolytes, glucose, and urea, which affect fluid balance in the body. It is a more accurate indicator of hydration status than just measuring fluid intake or output. Osmotic fragility is a test to assess the fragility of red blood cells, osteocalcin is a marker of bone metabolism, and oxalate is a test to assess the level of oxalate, which can lead to kidney stone formation but is not directly related to fluid and electrolyte balance.
