CRP / Albumin Ratio (CAR)

Specialist

also —

What it isA ratio of CRP to albumin — inflammation against nutritional and synthetic capacity.

DoesCaptures the catabolic state seen in chronic illness where inflammation rises and albumin falls.

GoodA low ratio signals quiescent inflammation and intact nutrition.

BadA high ratio predicts mortality across cancer, sepsis, heart failure, and chronic kidney disease — often better than either component alone.

Standard

Lab-specific.

Optimal

0–0.3 (lower is good)

Modifiers

Driven by both components.

How to optimize

Lifestyle: Resistance training to maintain albumin; address inflammation drivers.
Diet: Adequate protein; Mediterranean pattern.
Supplements: Omega-3 EPA+DHA (2–4g/day), curcumin (500mg 2×/day), whey protein if low albumin.
Peptides: —
Drugs: Treat underlying cause.
