24 hour urine collection is preferred but if a random urine is collected it MUST be acidified within 1 hour of collection - send to the laboratory immediately post collection.  Where possible, list medications the patient is taking.
All timed and 24hr urine oxalates require patient height and weight to calculate excretion/day and correction for surface area.
