• To explain unusual observations in Elispot data.
• To provide recommendations for reliable Elispot data acquisition.

Main Methods:

• Review of existing literature on Elispot analysis.
• Analysis of subjectivity and operator-dependency in automated Elispot reading.
• Inclusion of harmonization guidelines and international study findings.

Main Results:

• Plate evaluation is a significant source of variability in Elispot results.
• Even automated systems exhibit subjectivity and operator-dependency.
• Consensus guidelines for plate evaluation have been developed through international collaboration.

Conclusions:

• Standardized Elispot plate evaluation is critical for reproducible results.
• Understanding and mitigating analytical challenges are essential for accurate immune monitoring.
• This article provides a framework for navigating Elispot analysis algorithms and settings.
