Salivary IL ‐6 Shows Greater Intraindividual Stability Than Other Stress‐Related Cytokines in Young Adults

Key Points

• The aim is to compare the stability of salivary IL-6 with other stress-related cytokines in young adults.
• Data collection involved measuring salivary levels of IL-6 and other cytokines.
• Young adults were selected for the study.
• Stability assessments were conducted over multiple time points.
• Salivary IL-6 exhibited greater stability than other cytokines measured.
• Other stress-related cytokines showed more variability in levels.
• The findings suggest a unique reliability for IL-6 as a stress biomarker.
