Tubular reabsorption of a filtered substance is likely to be active rather than passive if its.

Concentration in the tubular fluid is lower than in peritubular capillary blood.
Excretion is increased by cooling the kidney.
Renal clearance is lower than that of inulin.
Renal clearance rises at high plasma levels.
Urinary excretion rate:plasma concentration ratio is the same as for glucose.
