Myths vs facts: hsCRP and Stress

hsCRP (high-sensitivity C-reactive protein) is a well-established marker of systemic inflammation, commonly used in cardiovascular risk assessment. Myth: Many assume hsCRP is a direct 'stress test' – this is incorrect. Acute psychological stress can transiently modulate inflammatory pathways, but hsCRP does not capture momentary stress levels. Fact: Chronic stress may contribute to low-grade inflammation via neuroendocrine mechanisms (e.g., cortisol, catecholamines), potentially leading to slightly elevated hsCRP. However, the evidence for a direct causal link is moderate at best; confounders such as diet, sleep, physical activity, and infections have a much stronger influence. A single hsCRP measurement is therefore not a reliable stress indicator. MyBody-X may include hsCRP in its blood test panels, but interpretation requires clinical context and professional guidance. Home tests have inherent limitations: they are not diagnostic and should be used as a screening tool, not a standalone assessment. For objective stress evaluation, validated questionnaires and diurnal cortisol profiling are more appropriate than relying solely on hsCRP.
