Quantitative 99m Tc-albumin colloid nasal mucociliary clearance as an outcome in primary ciliary dyskinesia.

NMC velocity discriminated highly significantly between patients with PCD and healthy controls. We suggest here a fast and feasible set up for NMC measurements that is easily applicable for any clinical trial involving PCD medication aimed for the nasal compartment, a step before or parallel to conducting clinical trials investigating whole-lung ciliary function in PCD.
