Diagnosis of Morquio A. Observation of careful unique clinical features and systemic skeletal radiographs of the patient will be the first step to suspect Morquio A differentiated from other MPS or skeletal dysplasia. Urine total GAG assay is less reliable, therefore, urine and blood KS test will be preferential. Enzyme assays should not be hesitated once the physician suspects Morquio A in spite of KS assay results. Once newborn screening is available, dried blood spot samples at newborn will be tested and diagnosis of Morquio A could be done prior to appearance of the unique signs and symptoms.
