The Claim

The association between loneliness and C-reactive protein (CRP) is consistent when measured using dried blood spots versus venous blood samples, indicating that the relationship is not influenced by the biological sampling method.

In plain English

Studies show that the link between feelings of loneliness and levels of C-reactive protein in the blood remains the same whether the blood is taken from a vein or collected via a finger-prick dried spot. This suggests the connection is real and not caused by how the blood sample is collected.

See the scientific wording

The association between loneliness and C-reactive protein (CRP) is consistent across two different biological sampling methods—dried blood spots and venous blood samples—suggesting that the relationship is not an artifact of measurement technique.

Why this might work

When someone feels lonely for a long time, their body stays in a state of mild stress, which causes certain chemicals to be released that tell the body to make more inflammation markers, like CRP, no matter how the blood is collected.

1 study

  1. Study: The reciprocal associations between social deficits, social engagement, and inflammation: Longitudinal evidence comparing venous blood samples and dried blood spots and mapping the modifying role of phenotypic and genotypic depression.

    Scientists checked if loneliness raises inflammation (CRP) using two different ways to measure blood—finger prick and arm draw—and found the same result both times. This means loneliness really is linked to inflammation, not just a quirk of how they took the blood sample.
