The fluorescent antibody technique makes it possible to establish the diagnosis of pertussis during the catarrhal period of the disease -- a period in which the disease is particularly difficult to identify -- in less than one hour. This technique is more sensitive than the method of cultivating nasopharyngeal mucus on Bordet-Gengous medium during the catarrhal period 95 compared with 86. However, after this period this technique must always be accompanied by a bacteriological diagnosis which becomes more sensitive after the first week of coughing fits 85 compared with 75.
