Background:

Viral infections pose significant risks to immunocompromised patients, including renal transplant recipients and those undergoing hematology-oncology treatment.
Timely and accurate viral diagnosis is crucial for effective patient management and treatment strategies in these vulnerable populations.
Decentralized laboratory services may offer advantages in speed and accessibility for viral pathogen identification.

Purpose of the Study:

To compare the performance of a hospital-based satellite laboratory with a state-wide reference laboratory for viral isolation.
To evaluate the efficiency, accuracy, and cost-effectiveness of a satellite laboratory model for viral diagnostics.

Main Methods:

A hospital-based satellite laboratory was established for primary viral isolation.
Clinical specimens from renal transplant and hematology-oncology patients were submitted to the satellite lab.
Paired specimens were also sent to a state-wide reference laboratory for comparative analysis.
Viral isolates, turnaround times, and costs were compared between the two systems.

Main Results:

The hospital-based laboratory identified 12 viral isolates from 97 clinical specimens.
For the first 50 paired specimens, the hospital lab identified 7 isolates, while the state lab identified 6.
The average turnaround time for the hospital lab was 9.2 days, compared to 11.2 days for the state lab.
The cost per specimen for the hospital lab was $18.10, comparable to routine bacteriology.

Conclusions:

A hospital-based satellite laboratory system provides rapid, accurate, and accessible viral diagnosis.
This decentralized model is a cost-effective approach for identifying viral pathogens in high-risk patient groups.
Implementing satellite laboratories can improve patient care through timely diagnostic results.
