any anomaly in the two-step process beginning with the active or passive extraction of substances (such as water, glucose, oligopeptides, amino acids, sodium (Na+) and other ions) from the renal tubule fluid into the renal interstitium, and the subsequent transport of these substances out of the renal interstitium back into the bloodstream; reabsorption begins in the proximal convoluted tubules and continues in the loop of Henle, distal convoluted tubules, and collecting tubules
