Of all the differences between GLP-1 telehealth programs, lab work requirements are the most revealing. A provider's approach to laboratory testing tells you more about their clinical philosophy than their website copy ever will.
Providers that require comprehensive baseline labs and periodic follow-up testing are investing in patient safety. Providers that prescribe GLP-1s without any lab work at all are prioritizing speed and convenience over clinical rigor. Both approaches exist in the current market. Here's how to tell the difference.
Why Lab Work Matters for GLP-1 Patients
GLP-1 medications affect multiple body systems beyond appetite and weight. Responsible prescribing requires understanding your baseline metabolic status and monitoring for changes during treatment. The key markers include:
- Kidney function (BUN, creatinine, eGFR): GLP-1s can cause dehydration due to reduced fluid intake and GI side effects. Patients with pre-existing kidney issues are at higher risk, and kidney function should be monitored.
- Thyroid markers (TSH, T3, T4): GLP-1 medications carry a boxed warning about thyroid C-cell tumors in rodents. While the risk in humans is not established, thyroid monitoring is part of responsible prescribing.
- Metabolic panel (fasting glucose, HbA1c, lipids): These markers establish your metabolic baseline and help track the systemic benefits of treatment beyond weight loss.
- Liver function (ALT, AST): GLP-1s may affect liver enzymes, and patients with non-alcoholic fatty liver disease — common in the population seeking weight loss medication — need monitoring.
- Pancreatic markers (lipase, amylase): While pancreatitis from GLP-1s is rare, elevated pancreatic enzymes warrant attention, especially in patients with risk factors.
What We Found Across Providers
Tier 1: Comprehensive lab programs
The best programs require baseline lab work before the first prescription and follow-up labs at 3-month and 6-month intervals (at minimum). Labs are either included in the program cost or facilitated through a partner lab at a disclosed price. Results are reviewed by the prescribing clinician, and the treatment plan is adjusted based on findings.
These programs may cost slightly more — lab work isn't free, and clinician time to review results costs money. But they're practicing medicine the way it's supposed to be practiced.
Tier 2: Labs recommended but not required
Many providers "recommend" lab work but make it optional. They'll suggest you get labs through your primary care provider or a direct-to-consumer lab service, but they'll prescribe the medication regardless of whether you do. The results, if obtained, may or may not be reviewed by the prescribing clinician.
This isn't negligent — there's a reasonable argument that requiring labs creates a barrier to access. But it does mean the provider is prescribing without the full clinical picture, and the patient is responsible for their own monitoring.
Tier 3: No lab work at all
At the bottom of the spectrum, some providers prescribe GLP-1 medications based solely on an online questionnaire with no lab work — not required, not recommended, not even mentioned. These programs are optimized for speed and conversion: complete the form, get approved, start medication.
What to Ask Your Provider
- Do you require baseline lab work before prescribing? If so, which panels?
- Is the cost of lab work included in my subscription, or is it additional?
- How often do you recommend follow-up labs? Who reviews the results?
- What happens if my lab results show a concerning finding — does it change my treatment plan?
- If I bring lab results from my primary care physician, will you review them?
These providers include or strongly support lab monitoring as part of their programs:
