Real-world studies and clinical applications, however, often face challenges such as non-compliance, imprecise self-reporting, and logistical constraints, which can jeopardize data quality.

This expert-led webinar discusses practical, scalable ways for ensuring reliable cortisol outcomes in research, clinical, and applied contexts. The goal is to improve data integrity while remaining feasible in field-based and large-cohort settings.

The webinar covers the following:

1. Foundations of reliable cortisol assessment

• Required timing windows for diurnal and CAR sampling
• Common causes of mistakes
• The effect of non-adherence on assay validity

2. Digital tools and workflow advancements

• Objective sampling-time verification via barcode technology or app-based tracking
• Provides automated reminders and protocol assistance
• Integrating contextual data from wearables and sleep trackers

3. From sample to assay

• Tube preparation, labeling, and tracking
• Storage, transportation, and pre-analytical variability
• Ensure compatibility with high-sensitivity cortisol immunoassays

The session covers practical insights from large-scale field applications and Tecan's solutions, and concludes with a live Q&A to address participant-specific issues.
