Lab Requirements Compared: Bloodwork vs. Questionnaire-Only GLP-1 Providers

The JAMA study published in July 2026 — a secret-shopper investigation of GLP-1 telehealth providers — found that many platforms prescribed medication based on minimal medical evaluation. The study reignited a debate that patients should understand: how much medical screening should happen before you start a GLP-1?

We reviewed the intake requirements at 10 providers and categorized them by the level of medical evaluation performed before prescribing.

The Lab Requirements Table

Why Labs Matter (and When They Don't)

The case for bloodwork before GLP-1 prescribing

GLP-1 medications are generally safe, but they interact with existing metabolic conditions. A baseline metabolic panel can identify:

• Kidney function: GLP-1s can cause dehydration-related kidney stress, especially with nausea. Patients with undiagnosed kidney impairment need closer monitoring.
• Thyroid markers: Semaglutide and tirzepatide carry a boxed warning about thyroid C-cell tumors (based on rodent data). A baseline thyroid panel provides a reference point.
• A1C and fasting glucose: If you have undiagnosed prediabetes or type 2 diabetes, your provider should know — it affects dosing, monitoring, and medication choice.
• Liver enzymes: GLP-1s are metabolized differently than most drugs, but liver function baseline is good clinical practice for any new medication.

The clinical consensus: baseline labs aren't strictly required for a healthy patient with no risk factors, but they're considered best practice — especially for patients over 40, those with family history of metabolic disease, or those taking other medications.

The case for questionnaire-only intake

Most patients starting GLP-1 medication are healthy enough that a detailed health history questionnaire captures the relevant information. A 28-year-old with a BMI of 31, no medications, and no family history of thyroid disease doesn't necessarily need bloodwork before starting low-dose semaglutide — a thorough questionnaire covering medical history, current medications, and contraindications may be sufficient for a competent prescriber to make a safe decision.

The speed advantage of questionnaire-only intake is real: providers like GobyMeds and Embody can get medication shipped in 2–3 days partly because they don't wait for lab results. For patients who've already had recent bloodwork through their PCP, requiring duplicate labs is unnecessary cost and delay.

The Red Flags: When "No Labs" Is a Problem

A questionnaire-only intake is reasonable when the questionnaire is thorough. But the JAMA study highlighted a different pattern: some providers' questionnaires were so brief that clinically relevant information was never collected. Signs of an inadequate intake, regardless of lab requirements:

• No medication interaction screening: If the questionnaire doesn't ask about your current medications, the prescriber can't check for interactions.
• No health history beyond BMI: If the only medical question is your height and weight, the evaluation is insufficient.
• No follow-up plan: If the provider prescribes medication with no scheduled follow-up or monitoring plan, you're on your own for side effect management and dose adjustment.
• No contraindication screening: GLP-1s are contraindicated in patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. If nobody asks, nobody checks.

What You Can Do Regardless of Provider

If your chosen provider doesn't require labs, you can still get them on your own:

• Ask your PCP: Request a basic metabolic panel and thyroid panel at your next primary care visit. Mention that you're starting GLP-1 medication.
• Direct-to-consumer labs: Services like Quest Direct and Labcorp OnDemand let you order bloodwork without a doctor's order for $50–150.
• Share results with your telehealth provider: Most platforms accept uploaded lab results even if they don't require them. Found and Oak both incorporate existing labs into their evaluation.

Methodology

Lab requirements verified against provider intake flows, FAQ pages, and Terms of Service as of September 2026. "Required" means the provider will not prescribe without lab results. "Offered" means the provider can order labs for you or incorporates them into evaluation if provided. "Not offered" means the intake flow does not address labs.
