Lab Monitoring Summary
Regular lab monitoring on GLP-1 treatment tracks health improvements beyond the scale. Most patients see significant improvements in metabolic markers within 3-6 months of starting semaglutide or tirzepatide.
Recommended Lab Schedule
| Test | Baseline | 3 Mo | 6 Mo | Annual | Expected |
|---|---|---|---|---|---|
| A1C / Fasting Glucose | X | X | X | X | Decrease |
| Lipid Panel (LDL, HDL, TG) | X | - | X | X | Improve |
| Liver Enzymes (ALT/AST) | X | X | X | X | Normalize |
| Kidney Function (BUN/Cr) | X | X | X | X | Stable |
| Thyroid (TSH) | X | - | X | X | Monitor |
| CBC | X | - | X | X | Stable |
| Vitamin B12 | - | - | X | X | Monitor |
| CRP (inflammation) | X | - | X | X | Decrease |
What to Watch For
Positive Trends
- A1C dropping below 5.7% (non-diabetic range)
- Triglycerides normalizing below 150
- Liver enzymes returning to normal range
- CRP decreasing (reduced inflammation)
Alert Your Provider
- Rising creatinine or declining GFR
- Elevated amylase or lipase (3x normal)
- Low B12 levels developing
- Thyroid values shifting significantly

Frequently Asked Questions
What labs should I get before starting GLP-1?
Baseline labs should include: comprehensive metabolic panel (CMP), lipid panel, A1C, fasting glucose, thyroid panel (TSH), CBC, liver enzymes (ALT/AST), and kidney function (BUN/creatinine). These establish your starting point for tracking improvement.
How often should I get bloodwork on GLP-1?
Recommended schedule: baseline before starting, 3 months after starting, 6 months, then annually. More frequent testing may be needed if you have diabetes, thyroid conditions, or kidney disease. Your provider will customize the schedule.
What improvements should I expect in my labs?
Most patients see: A1C decrease 0.5-1.5%, triglycerides drop 20-30%, LDL decrease 5-15%, ALT/AST normalize, fasting glucose improve 10-30 mg/dL, CRP decrease 30-50%, and blood pressure reduction 5-10 mmHg. Changes are typically visible by 3 months.
Should I be concerned about any lab changes on GLP-1?
Watch for: rising creatinine (kidney function), increasing amylase/lipase (pancreatitis risk), dropping too-low blood sugar if diabetic, B12 deficiency with long-term use. Report any abnormal results to your healthcare provider promptly.
