The rationale for this study is to demonstrate the potential of the CandyCollect platform for acquisition of samples from children in the clinic. With deliberate design to maximize collection performance from saliva sampling, the investigators long-term vision is that the CandyCollect platform will achieve better sensitivity and specificity than can be obtained with current biospecimen collection techniques, while providing a platform that is preferred by patients and usable in home settings. Ultimately, the CandyCollect has the potential to make saliva sampling a new gold standard for respiratory disease diagnostics and prevent the discomfort associated with a pharyngeal swab.~Intervention: Pediatric participants diagnosed with GAS via rapid antigen detection test (RADT) will be asked to suck on a swab for 10 seconds, like sucking on a lollipop. They will then be asked to suck on a candy lollipop that will collect their saliva. Participants will do each type of saliva collection twice-two swabs, then two lollipops. Afterwards, participants (both pediatric and caregiver) will fill out a short survey asking about their feelings and opinions about the different types of tests.~Specific aims:~Aim 1: The primary aim of this study is to assess the efficacy of the CandyCollect platform to capture and detect GAS in a small scale clinical study. The investigators will compare results of the CandyCollect sampling with both the RADT, which is the current gold standard, as well as a lollipop swab.~Aim 2: The secondary aim of this study is to evaluate the usability of the CandyCollect device by surveying pediatric participant and parent experience, acceptance of the collection technique, and their willingness to perform the test at home.~Hypotheses to be tested:~Aim 1: The CandyCollect platform is non-inferior to gold-standard RADT for GAS.~Aim 2: Pediatric participants and their parent/legal guardians will have a more positive experience with the CandyCollect than the RADT throat swab or the lollipop swab, and they will be willing to do the CandyCollect at home.
This study will enroll children ages 5-17 who test positive for Group A Streptococcus (GAS) at a single clinic visit lasting approximately 30 minutes. The primary aim of this study is to assess the accuracy and feasibility of the CandyCollect platform to capture and detect GAS. The investigators hypothesize that the CandyCollect platform is non-inferior to gold-standard rapid antigen detection testing for GAS.
