1. Collect a random urine specimen.
2. No preservative.
1. A timed 24-hour collection is the preferred specimen for measuring and interpreting this urinary analyte. Random collections normalized to urinary creatinine may be of some clinical use in patients who cannot collect a 24-hour specimen, typically small children. Therefore, this random test is offered for children <16 years old.
2. Any drug that causes alkalemia or acidemia may be expected to alter citrate excretion and should be avoided, if possible.
