When is CRP Check actually useful?

Based solely on the provided context, there is no information about when a CRP Check is actually useful. The context covers IgG food sensitivity tests, DNA tests for allergies, gluten avoidance, longevity tests, and sports genetics, but does not mention C-reactive protein (CRP). In general medical practice, CRP is useful for detecting and monitoring inflammation, such as in infections or chronic inflammatory conditions. High-sensitivity CRP (hs-CRP) can also aid in cardiovascular risk assessment. However, without supporting context, the evidence for the utility of a CRP Check in this specific setting is unclear. Consumers should rely on clinical guidance rather than direct-to-consumer marketing claims.
