This work is a retrospective analysis of real-time polymerase chain reaction (RT-PCR) results for SARS-Co V-2 from 888,665 saliva samples using Dorfman pooling. From August 2020 to February 2022, 56,515 pools of varying sizes and 54,194 individual samples were tested, with 39,928 samples excluded for various reasons.

Individuals with or without symptoms of upper respiratory tract infection, aged 18 years or older, who visit Valby or Hillerød test center for reverse transcriptase–polymerase chain reaction (RT-PCR) testing for SARS-Co V-2 will be offered participation in the study.
The exclusion criteria are individuals with a tracheostomy, laryngectomy, or prior oropharyngeal cancer surgery that would make the throat swab difficult.

Assessing SARS-CoV-2 Testing Adherence in a University Town: Recurrent Event Modeling Analysis
Polymerase chain reaction (PCR) testing accessibility was enhanced with the establishment of new testing locations offering voluntary and complimentary SARS-Co V-2 testing. HDT engaged over 200 public health ambassador students dedicated to advocating for healthy behaviors. Mass communication campaigns were promoted across diverse media platforms to encourage testing and the adoption of health-promoting behavior. The program provided incentives to promote health-promoting behaviors.

PCR and PCR-like technologies (nucleic acid amplification technologies [NAATs]) are considered the gold standard for detection of viral pathogens, but due to the extreme need for tests, the national RT-PCR testing capacity was unable to meet the overall testing demand. Consequently, RATs, which may be performed by non-health-care-trained individuals outside of health care facilities with results within minutes, were implemented on a large scale.

Until now, we are aware of two studies successfully implementing a regular surveillance program for the monitoring of SARS-Co V-2 infections in schools, both of which involve collection of swabs by health care staff for real-time reverse transcription polymerase chain reaction (r RT-PCR) testing [33,34]. Despite massive expansion of testing capacities, however, regular testing and provision of rapid results for all school children would place a substantial logistical burden on schools.

The polymerase chain reaction (PCR)–based tests are effective for diagnostic testing that looks for the SARS-Co V-2 virus’s genetic material, which causes COVID-19 [4]. As per the Centers for Disease Control and Prevention recommendations [4], the PCR test is the gold standard and accurate method for detecting, tracking, and studying COVID-19 [5].
The COVID-19 pandemic is especially challenging for laboratories tasked with rapid and reliable testing of an increased number of PCR tests [6].

Qualitative real-time polymerase chain reaction (RT-PCR) of nasopharyngeal secretions is the gold standard for testing respiratory viruses, including SARS-Co V-2 [1]. However, major concerns have been raised regarding false-negative rates of RT-PCR tests in community testing locations [2]. An early retrospective review of community hospital testing performed in China reported a test sensitivity of only 71% [3].

We propose methods to validate multiple sample types for RNA-PCR (polymerase chain reaction) and for serology tests. Proposed specimen types and assays are depicted in Table 1.
Specimen types and assays to be performed in an evaluation of diverse samples for SARS-Co V-2 (severe acute respiratory syndrome coronavirus 2) RNA and antibody testing.
a Ig G: immunoglobulin G.
b Ig M: immunoglobulin M.
c Ig A: immunoglobulin A.
Patients will be provided with printed instructions for collection (Figure 1).
