Summary
Hypercube pooling for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) screening has a quantization effect. This study determined the optimal edge and dimension for hypercube pooling to improve PCR test efficiency during pandemics.
Area of Science:
- Virology
- Epidemiology
- Biostatistics
Background:
- Large-scale screening is crucial for controlling the SARS-CoV-2 pandemic.
- Hypercube pooling PCR offers speed and efficiency for sample testing.
Purpose of the Study:
- To evaluate the effectiveness of hypercube pooling for SARS-CoV-2 screening.
- To determine the optimal edge and dimension for hypercube pooling strategies.
- To develop a computational tool for optimizing pooling strategies.
Main Methods:
- A C++ program was developed to calculate the expected number of PCR tests per patient.
- Simulations were performed across various prevalence, edge, and dimension values.
- The program identified optimal edge and dimension parameters for hypercube pooling.
Main Results:
- Hypercube pooling with edge = 3 may not be the optimal strategy due to quantization effects.
- Each edge value demonstrated a specific range of best performance.
- The study identified optimal edge and dimension combinations based on disease prevalence.
Conclusions:
- The optimal hypercube pooling strategy is dependent on disease prevalence.
- The developed C++ program can assist in selecting optimal pooling parameters.
- This tool aims to enhance the efficiency of SARS-CoV-2 pandemic control efforts.
