What analyte is affected by ascorbic acid?

Ascorbic acid can interfere with many clinical chemistry assays because it is a strong reducing agent and can alter colorimetric or enzymatic reactions used to quantify analytes. Its presence can skew the signal that a test relies on, leading to inaccurate readings. In this set of choices, the measurement of urea is the one most affected by ascorbic acid in typical assay setups, which can produce an artificially higher reading. The other analytes are also susceptible to interference in some methods, but the scenario here points to urea showing an increased result when ascorbic acid is present. To avoid such interference, labs may use methods designed to be less sensitive to reducing agents or treat samples to remove ascorbate before testing.
