Atherogenic Index of Plasma (AIP) Calculator
Metabolic Relevance
AIP = log₁₀(Triglycerides/HDL-C) correlates strongly with LDL particle size (r = 0.803). A negative AIP indicates HDL exceeds triglycerides — representing excellent cardiovascular protection. Dobiásová validation studies established AIP as a powerful predictor of atherosclerosis risk.
Recommended testing frequency:
Every 3-6 months with lipid panels, especially when monitoring metabolic interventions
Did you know?
AIP can be negative! When HDL exceeds triglycerides, the logarithm becomes negative — indicating large buoyant LDL particles and excellent cardiovascular protection. Athletes and low-carb dieters often achieve negative AIP values.
AIP responds faster to dietary changes than LDL-C. Carbohydrate reduction can dramatically lower triglycerides within 2-4 weeks, rapidly improving your AIP score.
