What Are the Challenges in Laboratory-Based Surveillance?

Despite its advantages, laboratory-based surveillance faces several challenges:

Resource Intensity: It requires significant financial, technical, and human resources.
Data Integration: Integrating laboratory data with other surveillance data can be complex.
Timeliness: Delays in sample collection, transport, and testing can impact the timeliness of data.
Quality Control: Ensuring the quality and consistency of laboratory tests across different sites can be difficult.
Data Sharing: Legal and ethical issues can hinder the sharing of laboratory data across jurisdictions.
