15 entries
ApoB/ApoA-I ratio — lab reference
Approximate risk strata are sex-specific and assay-dependent.
Lipids and Cardiovascular Risk MarkersApolipoprotein A-I — lab reference
Assay-specific. Interpret with HDL and ApoB.
Lipids and Cardiovascular Risk MarkersApolipoprotein B — lab reference
90-99 above desirable; 100-119 borderline high; 120-139 high; ≥140 very high. Risk goals may be lower.
Lipids and Cardiovascular Risk MarkersBNP — lab reference
Age, kidney function, obesity, rhythm, and clinical setting affect interpretation.
Lipids and Cardiovascular Risk MarkersHDL cholesterol — lab reference
Higher HDL is not always protective; interpret within the entire risk profile.
Lipids and Cardiovascular Risk MarkersHigh-sensitivity CRP — lab reference
≥2 suggests higher cardiovascular risk; >10 may reflect acute inflammation and should generally be repeated when well.
Lipids and Cardiovascular Risk MarkersLDL cholesterol — lab reference
Risk-based goals may be <100, <70, or <55 depending on primary/secondary prevention risk.
Lipids and Cardiovascular Risk MarkersLDL particle number (LDL-P) — lab reference
Advanced lipoprotein testing. Use the performing laboratory classification.
Lipids and Cardiovascular Risk MarkersLipoprotein-associated phospholipase A2 — lab reference
Method, units, and cutoffs vary. Dr. Purser to decide whether to retain.
Lipids and Cardiovascular Risk MarkersLipoprotein(a) — lab reference
≥75 increased; ≥125 commonly treated as a risk-enhancing level. Units are not directly interchangeable with mg/dL.
Lipids and Cardiovascular Risk MarkersNon-HDL cholesterol — lab reference
Risk-based goals may be lower; useful when triglycerides are elevated.
Lipids and Cardiovascular Risk MarkersNT-proBNP — lab reference
Use assay- and indication-specific rule-out/rule-in thresholds.
Lipids and Cardiovascular Risk MarkersTotal cholesterol — lab reference
Screening measure, not a stand-alone treatment target.
Lipids and Cardiovascular Risk MarkersTriglycerides — lab reference
150-199 borderline high; 200-499 high; ≥500 severe and pancreatitis-relevant.
Lipids and Cardiovascular Risk MarkersVLDL cholesterol — lab reference
Often calculated. Less reliable when triglycerides are markedly elevated.
