crystalloid solution

Transfusion medicine A balanced isotonic solution–eg, Ringer's lactate or saline fluid solution, used for volume expansion. Cf Colloid solution.


1. resembling a crystal.
2. a noncolloid substance. Crystalloids form true solutions and therefore are capable of passing through a semipermeable membrane, as in dialysis. The physical opposite of a crystalloid is a colloid (3), which does not dissolve and does not form true solutions.

crystalloid particle
a matrix particle in a single membrane contained in a peroxisome, when viewed through an electron microscope. Called also nucleoid.
crystalloid solution
contains electrolytes and nonelectrolytes which will diffuse into all body fluid compartments. Examples are Ringer's solution and 5% dextrose in water.
