Preparation:Ship specimens Monday through Friday to avoid delays. Carefully read all instructions and review the collection procedures before starting. This test requires a first morning urine sample and has no special dietary restrictions. If taking sulfur-containing medications or supplements (e.g., DMSA, DMPS, MSM), complete the course and wait 4 days before collecting your sample. Certain medications, including barbiturates, tranquilizers, digoxin, quinidine, and alcohol, may elevate D-glucaric acid levels. Avoid non-essential medications, supplements, and alcohol for 72 hours before and during collection unless directed otherwise by your physician. Do not discontinue prescription medications without consulting your doctor. Female patients should avoid collecting urine during menstruation.
Test Results:
5-7 business days once the lab receives the specimen. May take longer based on weather, holiday, or lab delays.
