Splay is a physiological term that refers to the difference between urine threshold (the amount of a substance required in the kidneys before it appears in the urine) and saturation, or TM; in this instance, saturation refers to an exhausted supply of renal reabsorption carriers. In simpler terms, splay is the concentration difference between a substance's maximum renal reabsorption vs. appearance in the urine. Splay is usually used in reference to glucose; other substances, such as phosphate, have virtually no splay at all.
