Levels of iron in bronchoalveolar lavage fluid (BAL) from normal volunteers and PAP patients. Metal concentrations in the bronchoalveolar fluid of PAP patients were elevated relative to values in healthy controls. All concentrations of iron were low relative to those normally found in blood (about 100 micrograms/dL). * significantly greater than normals; p < 0.05.
