Answer

A delay in the diagnosis of acute poststreptococcal glomerulonephritis (APSGN) is sometimes related to the absence of a clear history of a preceding documented streptococcal infection. [44] This may be due to more stringent definition criteria that require documented evidence of past infection by streptococci. Typically, an acute nephritic syndrome develops 1-2 weeks after an antecedent streptococcal pharyngitis, whereas a lapse of 3-6 weeks is common before a nephritic syndrome develops following streptococcal pyoderma.
