The identification aids in the diagnosis of diseases caused by bacteria belonging to the genus Streptococcus and provides epidemiological information on these diseases. Pathogenic streptococci are associated with infections, such as sore throat, impetigo (an infection characterized by small pustules on skin), urinary tract infections, rheumatic fever, and kidney diseases. Abbott TestPack Plus Strep A with On Board Controls (OBC) II is a rapid immunoassay for the qualitative detection of Group A Streptococcal (Group A Strep) antigen in throat swab specimens from patients with suspected Group A Strep associated pharyngitis and for confirmation of presumptive Group A Strep colonies isolated on culture plates. ## Device Story Rapid immunoassay for qualitative detection of Group A Streptococcal antigen. Input: throat swab specimens or presumptive Group A Strep colonies from culture plates. Principle: immunoassay utilizing internal on-board control system (six control features) to verify assay performance. Output: qualitative visual result indicating presence of Group A Strep antigen. Used in clinical settings by healthcare professionals. Assists clinicians in diagnosing pharyngitis and confirming culture results. Benefits patients by providing rapid identification of Group A Strep, facilitating timely clinical decision-making. ## Clinical Evidence Clinical study of 445 throat swabs from five U.S. sites. Compared to SBA culture: sensitivity 92.9% (EOA) to 94.6% (10 min), specificity 97.9% (EOA) to 97.0% (10 min). Compared to SSA culture: sensitivity 90.4% (EOA) to 92.2% (10 min), specificity 97.9% (EOA) to 97.0% (10 min). ## Technological Characteristics Rapid immunoassay; includes internal on-board control system with six control features. Qualitative detection of Group A Strep antigen. Requires specimen processing. ## Regulatory Identification Streptococcus spp. serological reagents are devices that consist of antigens and antisera (excluding streptococcal exoenzyme reagents made from enzymes secreted by streptococci) used in serological tests to identify Streptococcus spp. from cultured isolates derived from clinical specimens.

Substantial equivalence has been demonstrated between TestPack Plus Strep A with OBC II and the results obtained through isolation of Group A Strep colonies on sheep blood agar medium followed by a serological grouping of presumptive Group A Strep. TestPack Plus Strep A with OBC II is a rapid immunoassay for the qualitative detection of Group A Streptococcal antigen from throat swab specimens or confirmation of presumptive Group A Strep colonies recovered from culture. The intended use of both is for the qualitative detection of Streptococcus pyogenes. Both can be used with throat swab specimens. TestPack Plus Strep A with OBC II detects Strep A specific antigen, whereas, culture and confirmation by typing identify growth of the Streptococcus pyogenes organisms. TestPack Plus Strep A with OBC II can be used for both the qualitative identification of Group A Strep antigen and the confirmation of suspect colonies from culture, whereas, culture and confirmation by typing can only be used for the qualitative detection of Streptococcus pyogenes organisms. TestPack Plus Strep A with OBC II utilizes an internal on board control system consisting of six control features, however, culture does not contain any internal controls. TestPack Plus Strep A with OBC II requires processing of the throat swab specimen, however, culture does not require processing of the throat swab specimen. TestPack Plus Strep A OBC II 510(k) April 1997 ebc310ka.lwp Attachment A Page 1 of 2 {1}------------------------------------------------ Clinical testing was performed on 445 throat swabs collected at five U.S. clinical sites from patients seeking medical attention for pharyngitis. Each swab was used to inoculate 5% Sheep Blood Agar (SBA) and Strep Selective Sheep Blood Agar (SSA) culture plates within 30 minutes of collection. The culture plates were aerobically incubated at 35 to 37℃. Suspect beta-hemolytic colonies were confirmed as Group A Strep by a latex agglutination test. When compared to SBA culture, TestPack Plus Strep A with OBC II assay demonstrated a sensitivity of 92.9% at End of Assay (EOA) and 94.6% at 10 minutes after specimen addition, a specificity of 97.9% at EOA and 97.0% at 10 minutes after specimen addition, and an agreement of 96.6% at EOA and 96.4% at 10 minutes after specimen addition for all sites combined. When compared to SSA culture, TestPack Plus Strep A with OBC II assay demonstrated a sensitivity of 90.4% at EOA and 92.2% at 10 minutes after specimen addition, a specificity of 97.9% at EOA and 97.0% at 10 minutes after specimen addition, and an agreement of 96.0% at EOA and 95.7% at 10 minutes after specimen addition for all sites combined. In conclusion, these data demonstrate that the TestPack Plus Strep A with OBC II assay is as safe and effective as, and is substantially equivalent to the results obtained through isolation of Group A Strep colonies on SBA culture plates or SSA culture plates.
