Litholink Metabolic Panel, 24 Hr Urine Panel

Message

This test is ordered by Urology Staff Physicians who give a collection kit to the patient and place an order in CPRS. The patient sends the sample to the Litholink Laboratory, not to the VA Laboratory. Results are sent to the VA Laboratory so they can be entered in CPRS.

This test is currently only available in BHS CPRS. If you are a Bedford provider and wish to see this test offered in Bedford CPRS- please contact the Bedford Laboratory.
