It is important for the ordering physician to be aware that there is an in-house Mucopolysaccharides (MPS) screening test. The in-house test code is MPSU, for Mucopolysaccharides, Urine Spot Test. The in-house test is typically recommended first. Please be clear when ordering if both tests are intended to be ordered and supply enough sample for both in separate containers. For the reference lab test, it is important to include the patient's age. For best results, an early morning random urine sample is preferred. This test is most often associated with patients already diagnosed with MPS.
