Web1 Dec 2015 · The plasma glucose concentration at which the filtered glucose load reaches the Tm (375 mg/min) is called the threshold (Fig. 1). The theoretical plasma glucose threshold that corresponds to the Tm (375 mg/min) is ∼300 mg/dl. However, in healthy individuals, the plasma glucose threshold at which glucosuria begins is ∼180 mg/dl. Splay is usually used in reference to glucose; other substances, such as phosphate, have virtually no splay at all. The splay in the glucose titration curve is likely a result of both anatomical and kinetic differences among nephrons. A particular nephron’s filtered load of glucose may be mismatched to its capacity to reabsorb glucose.
