Why expand beyond standard labs
Standard panels (CMP, lipid panel, A1c) capture core metabolic health but miss patterns visible only with advanced markers. For patients with cardiometabolic risk factors, expanded monitoring is justified.
Markers worth adding
- HOMA-IR: insulin resistance score. Useful baseline + 6-month follow-up. Often improves substantially on GLP-1.
- ApoB: Better atherogenic burden estimator than LDL-C alone. Particularly informative if LDL appears normal but cardiometabolic risk is elevated.
- Lp(a): Genetic CV risk marker. Measured once (level doesn't change much). Not GLP-1-responsive, but informs overall CV risk picture.
- hs-CRP: Inflammation marker. Often improves with weight loss.
- Fasting insulin: Useful for HOMA-IR calculation; supplements glucose-only measures.
- 24-hour ABPM: For patients with white-coat hypertension or borderline office BP.
Expected changes on GLP-1
- HOMA-IR: typically substantial improvement
- ApoB: 5–15% decrease
- hs-CRP: variable, often improves with weight loss
- Lp(a): no expected change (genetic)
Cost considerations
Expanded markers add ~$100–$300 per panel beyond standard labs. Insurance coverage varies. For patients with established CV disease or T2D, often covered.
