Every time I do a sputum sample (unless it's asked for at clinic or GP's surgery) I always nebulise a bronchodilator followed by physio, so I can get sample from various areas of the lung. I always hesitate to nebulise saline 0.9% or hypertonic 7% in case it effects the sample in a negative way.
My question is does anyone know if nebulising saline directly before effects the sample in any way?
