What does a high HDL result mean?

A high HDL (high-density lipoprotein) result is traditionally considered 'good cholesterol' and associated with lower cardiovascular risk. However, recent evidence shows the relationship is nuanced: extremely high HDL levels (e.g., >90 mg/dL in men, >110 mg/dL in women) have been linked in some studies to increased risk of infections or even cardiovascular events. Moreover, HDL function (cholesterol efflux capacity, anti-inflammatory properties) matters more than the absolute number. A high HDL from a consumer lab test is a single biomarker that must be interpreted within the full lipid panel (LDL, triglycerides, non-HDL) and other risk factors (blood pressure, smoking, diabetes). Mendelian randomization studies have weakened the case for HDL as a causal protective factor; it is now viewed more as a risk marker than a therapeutic target. In practice, a high HDL is usually a favorable sign, but without medical context and lifestyle assessment (exercise, diet, alcohol intake), the value can be misleading. MyBody-X tests do not diagnose – if results are abnormal, consult a physician.
