| osmotic fragility t. |
(for spherocytosis): heparinized or defibrinated blood is placed in tubes of sodium chloride solution (pH 7.4) varying in concentration from 0.85 to 0.00 per cent (w/v); the amount of hemolysis in each tube is determined colorimetrically. Increased fragility indicates spherocytosis.

| osmotic p. |
the pressure required to stop osmosis through a semipermeable membrane between a solution and pure solvent; it is proportional to the osmolality of the solution and also to other colligative properties of the solution, including freezing point depression, vapor pressure depression, and boiling point elevation. Symbol π.

| osmotic p., effective |
