Some weight loss services skip labs entirely. We don't think that's responsible — and we know from experience that having baseline data dramatically improves outcomes. The good news: it's a focused panel, not the kitchen sink.
GLP-1 medications are remarkable when they fit; they're also not appropriate for everyone. Labs help your clinician make the right call.
Most members starting semaglutide or tirzepatide are well people who simply want help losing significant weight. For those members, the lab requirements are short — confirm there's no contraindication, establish a baseline, and ship the medication.
But some members have underlying issues that make GLP-1 medications either riskier or less effective than they could be. Subclinical hypothyroidism. Iron deficiency. Vitamin D insufficiency. PCOS. Insulin resistance that needs metformin alongside the GLP-1. Pre-diabetes that's about to flip into diabetes. Liver enzyme elevations from fatty liver disease. These are not exotic findings — they're common in adults whose weight has crept up over years, and they meaningfully change the optimal treatment plan.
HealifyNow's weight-loss lab panel is designed to catch the things that matter, without ordering tests that don't change anything. Your clinician explains every result, and we run a follow-up panel at 3-6 months to verify the medication is doing what it should.
HbA1c, fasting glucose, CMP (liver/kidney), CBC, TSH, lipid panel. Eight markers. ~$129.
Fasting insulin, vitamin D, B12, ferritin. Catches deficiencies that affect energy and weight loss.
Estradiol, FSH, progesterone if relevant. Identifies hormone patterns affecting weight (perimenopause, PCOS).
Combine with the full panel ($399) for the most thorough baseline and ongoing tracking.
From your first message to your medication arriving at your door — clinician-guided, every step.
A care team member meets with you to understand your goals, medical history, and treatment preferences. The first visit is no-cost and no-commitment — we want you to be confident before moving forward.
Connect by secure video or phone with a U.S.-licensed physician or nurse practitioner who reviews your full picture — labs, prior treatments, current medications, and lifestyle — and decides what is clinically appropriate.
If your clinician determines treatment is right for you, they issue a prescription that goes to a licensed U.S. pharmacy. We coordinate discreet shipping, or you can fill it locally. Follow-up visits are built in.
HbA1c. Your 3-month glucose average. Catches pre-diabetes and undiagnosed diabetes. Changes the medication choice (Mounjaro/Ozempic for diabetic; Wegovy/Zepbound for non-diabetic chronic weight management).
Fasting glucose and fasting insulin. Together they reveal insulin resistance before HbA1c does. If insulin is high, your clinician may add metformin alongside the GLP-1 for faster progress.
Comprehensive metabolic panel. Kidney function (we need this for dosing) and liver enzymes. Mild fatty-liver-pattern elevations are common in members who have carried weight for years; we monitor them on therapy.
Complete blood count. Anemia is common, especially in menstruating women. Iron-deficient members feel terrible on GLP-1 medications because the appetite suppression makes nutrient intake worse. Worth knowing.
TSH. Subclinical hypothyroidism affects ~5% of adults and dramatically reduces weight loss response. We treat it; weight loss responds.
Lipid panel. Establishes baseline cardiovascular risk. GLP-1 medications typically improve lipids substantially, which is one of their underappreciated benefits.
Vitamin D, B12, ferritin (optional). Three common deficiencies that drain energy and motivation. Cheap to check, easy to fix, big effect on how you feel during the program.
Your clinician will review every relevant detail with you. Here are the most important points to know up front.
Lab values don't replace a clinician talking through your history, medications, and goals.
Components may be covered if your PCP orders them. Our pricing is transparent.
Some members already have recent labs from their PCP and can submit those instead of running new ones.
GLP-1 prescribing does not require labs by federal law, but doing it without baseline data is irresponsible. We do.
All medications must be prescribed by a licensed provider based on medical necessity. Treatment is not suitable for everyone. Results may vary.
If you're starting a weight-loss program. sign up for the program first. Your clinician will identify which labs you need based on your intake. If you already have recent labs (within 6 months) from your PCP, those are usually fine — you can upload them during sign-up.
If you need new labs, we send a Quest or LabCorp requisition. You walk in for the draw, results come back in 3-5 business days, your clinician reviews them, and your prescription (if appropriate) follows.
On treatment, we re-check key markers at 3 months (HbA1c, lipid panel, liver enzymes) to verify the medication is working and not causing any unexpected effects. This is standard of care and most members find it reassuring.

"Glad they ran labs first. TSH was high — I was hypothyroid and didn't know it. Treated that alongside starting Wegovy. The combo was the actual unlock."
"My fasting insulin was 17. Started metformin with my GLP-1. Lost 31 lbs in five months. PCP had never checked fasting insulin."
"Annual physical labs from January were accepted. Saved me money and a draw. Smooth process all around."
HealifyNow makes it easy to move forward with confidence. Here are the answers to what people ask us most.
HealifyNow requires either recent (within 6 months) labs or a new draw before starting GLP-1 medications. We won't prescribe blind. Most members accept this as reasonable; it's standard of care.
Yes — if they include the core markers and were drawn within the last 6 months, we can use them. Upload the PDF during sign-up.
The required core panel runs about $129 as a standalone. The recommended add-ons (insulin, D, B12, ferritin) bring it to about $199. The comprehensive full panel ($399) covers everything.
Sometimes, if your PCP orders them through standard insurance billing. Our cash-pay pricing is transparent so you can compare and choose.
HbA1c, lipid panel, and liver enzymes at 3 months. Full re-panel at 6-12 months. We integrate the re-tests into your ongoing care without surprise fees.
Your clinician will explain it in plain language and tell you what it means for your weight-loss program — whether it changes the medication, adds a co-treatment (like metformin or thyroid replacement), or needs separate follow-up.
Yes. Many members fast overnight, get drawn first thing in the morning, then meet with the clinician once results post a few days later.
The draw is fast (5-15 minutes) and Quest/LabCorp technicians are professionals. You can request a smaller-gauge needle and use whatever distraction works for you. Most members are fine; we don't shame anyone for being nervous.
Book online and a licensed clinician orders the test for you, so no separate doctor's visit is needed. You then complete a quick blood draw at a Quest or LabCorp location near you.
You complete a quick blood draw at a Quest or LabCorp location near you. Your order confirmation explains exactly what to do and when.
Your instructions tell you whether fasting or any other preparation is needed. Blood panels that include glucose and lipids usually require an 8 to 12 hour fast.
Timing depends on the test. You're notified as soon as results are ready, and a licensed clinician reviews them with you.
A licensed clinician reviews every result, explains what it means in plain language, and recommends next steps, including treatment if appropriate.
Yes. Your results are stored on a HIPAA-compliant platform and shared only with you and your care team.
If results suggest a treatable issue, your clinician can discuss treatment options in a follow-up visit, and you can retest later to track progress.
Start with labs, get a real clinical picture, and begin treatment with confidence.
