Is hsCRP useful for Blutzucker?

The question of whether hsCRP (high-sensitivity C-reactive protein) is useful for blood sugar requires a nuanced answer. hsCRP is a well-established marker of systemic inflammation. Elevated levels (≥2 mg/L) are associated in observational studies with an increased risk of type 2 diabetes, as chronic low-grade inflammation contributes to insulin resistance. However, hsCRP does not directly measure blood glucose or glycemic control. Standard parameters for diabetes diagnosis and management remain fasting glucose, HbA1c, and oral glucose tolerance test. hsCRP can serve as an additional risk marker, particularly for cardiovascular risk assessment in diabetic patients. The evidence is based on numerous cohort studies and meta-analyses (human-moderate). No randomized controlled trials demonstrate a causal benefit of hsCRP measurement for blood sugar management. Additionally, reference ranges vary, and many confounders (infection, smoking, obesity) affect hsCRP levels. For consumers: an elevated hsCRP alone is not a diabetes test. It may be useful in a comprehensive risk evaluation but does not replace blood glucose measurements. Its utility is limited, and medical interpretation is required.
