Abstract
I was disturbed to read in "Immunologic Defects in Patients with Refractory Sinusitis" by Shapiro et al that I was quoted as saying "a normal response to pneumococcal immunization was defined as a rise to more than 200 ng/mL for antigens 3, 7, 9, and 14." In both those references as well as many other publications from my laboratory, I indicate that by radioimmunoassay, the only technique which my laboratory uses, 200 to 300 ng of antibody N/mL is a normal preimmunization level.
