Physical examination is notable for mucopurulent discharge from both nares and tenderness to palpation over her bilateral maxillae. Sputum gram stain shows gram-positive diplococci. Which of the following best describes the levels of immunoglobulins that would most likely be found upon testing this patient's serum??
