Fig. 1From: Study and interest of cellular load in respiratory samples for the optimization of molecular virological diagnosis in clinical practiceAverage cellularity of respiratory specimens depending on the sample type and age group. a Nasal aspirate was the sample type that provides, on average, more epithelial cells for patients under the age of 15 (5.70 Log/ml for aspirates versus 4.96 Log/ml for swabs). b Although having the same shape, the average cellularity curve of positive samples was always located above the negativesBack to article page
