LAB MONITORING
Labs that actually mean something.
GLP-1 therapy is metabolically active medicine. Labs before any prescription and every three months keep you safe, confirm the medicine is working, and catch what a small appetite quietly takes — iron, B12, magnesium, vitamin D — before it becomes a problem.
Without lab monitoring, you and your provider are guessing. The numbers tell us what is happening inside your body that a scale cannot — and they let your provider titrate your dose, adjust your supplements and your protein target, and protect your long-term health.
This is not the same as a yearly physical. GLP-1 medication changes how your body processes calories, hormones, and nutrients in a matter of weeks. The cadence has to match the medicine.
WHY EVERY THREE MONTHS
The cadence isn’t arbitrary — it’s how the medicine works.
Three months is when changes become measurable.
HbA1c reflects a roughly 90-day average. Lipid shifts stabilize at 8–12 weeks. Thyroid suppression patterns become readable. Earlier than that, the numbers are still noisy.
Three months is when dose-response patterns emerge.
Your provider can see whether the dose you are on is producing the metabolic shift it should — and adjust before the next quarter starts.
Three months catches subtle side effects before they escalate.
Kidney strain, liver stress, electrolyte shifts, and mineral deficiencies usually start subtle. Quarterly monitoring catches them while they are easy to correct.
Three months is when the nutrition markers move.
Iron, B12, magnesium and vitamin D drift down slowly on a small appetite. A quarterly recheck catches the drop while a supplement adjustment still fixes it — and confirms the ones you are taking are working.
WHAT WE ORDER
The panels — and why each one matters.
Every patient gets the core panel and the nutrition and bone panel at baseline. The core panel repeats every quarter; the nutrition markers are rechecked on the schedule your results set. Hormone, metabolic and bone-turnover markers are added only when your case calls for them.
THE CORE PANEL · EVERYONE, BASELINE AND QUARTERLY
PANEL 01
Comprehensive Metabolic Panel (CMP)
Glucose, kidney function (BUN, creatinine), liver enzymes, electrolytes, calcium and albumin. Catches the early signs of dehydration, kidney strain or liver stress that GLP-1 medications can occasionally trigger, before they become problems.
PANEL 02
Lipid Panel
Total cholesterol, LDL, HDL, triglycerides. GLP-1 therapy often improves lipid markers — but not always. We track every quarter to confirm the improvement is real and to catch the patients whose markers move the wrong direction.
PANEL 03
HbA1c
Three-month average blood sugar. The clearest single marker of how the medication is shifting your metabolic state. Especially important if you have prediabetes or type 2 diabetes.
PANEL 04
Thyroid (TSH, reflex free T4)
Checked at baseline and whenever symptoms suggest it, because untreated thyroid disease undermines weight loss and its symptoms can look just like GLP-1 fatigue from the outside.
PANEL 05
Complete Blood Count (CBC)
Anemia screen and safety baseline. Read together with your iron and B12 results.
PANEL 06
Vitamin D (25-OH)
Commonly low at baseline. Repletion supports bone and muscle during weight loss, and it is one of the levers behind your supplement plan.
THE NUTRITION & BONE PANEL · EVERYONE AT BASELINE
PANEL 07
Ferritin and iron panel
Iron deficiency is the most common deficiency in obesity and gets worse on a small appetite. Fatigue and hair loss on a GLP-1 are often iron. Rechecked whenever it is low or iron is started.
PANEL 08
Vitamin B12 and folate
Both fall with lower animal-protein, vegetable and legume intake; B12 also drops on metformin. Low B12 carries a nerve and anemia risk that is easy to prevent.
PANEL 09
Magnesium
Low on a restricted intake and on some common medications. It is behind cramps and palpitations, and it is needed to activate vitamin D. Rechecked every quarter.
PANEL 10
Zinc and phosphorus
Zinc falls with low intake and shows up as hair loss and taste change, which lowers appetite further. Phosphorus is part of bone mineral balance and flags refeeding physiology or vitamin D deficiency.
ADDED WHEN YOUR CASE CALLS FOR IT
Hormones (when indicated)
Estradiol, FSH, testosterone, DHEA-S, morning cortisol. Ordered when your history — perimenopause, menopause, PCOS, symptoms of low testosterone — suggests a result would change the plan. Elysiv does not prescribe hormone or testosterone therapy; where it is indicated, we refer you.
Metabolic and inflammation markers (when indicated)
Fasting insulin, hs-CRP, uric acid and a liver fibrosis score. Ordered on the Metabolic Optimization track and when your baseline suggests fatty liver or insulin resistance is part of the picture.
Bone turnover markers (higher-risk patients)
CTX and P1NP. Rising turnover during rapid weight loss identifies who needs protein, calcium and strength work tightened. Reserved for patients at real fracture risk; not a routine test.
BODY COMPOSITION
Labs every quarter. Your scale every month.
Blood work tells you what is happening inside; it does not tell you what the weight you are losing is made of. That is what the body-composition scale is for. It ships after your video visit, it is yours to keep, and it measures weight, body fat and lean mass at home.
Your provider reads the fat and lean-mass trend with you at every monthly follow-up, alongside your labs and your strength work — and adjusts your protein target, your supplements and, if you are on one, your dose. In some trials, 40–60% of the weight lost on GLP-1 medication was lean mass; the scale is how we make sure yours is fat.

HOW IT WORKS
Where you go — and how it’s billed.
Where
Your provider sends the order to a Quest Diagnostics or Labcorp near you. Walk in, walk out — no appointment needed for routine panels. Results route back to your provider, who walks through them with you in plain English.
Billing
Baseline and quarterly labs are included in your $395 monthly membership and are ordered under Elysiv’s account at Quest or Labcorp. No separate bill from the lab; nothing is billed to your insurance. The cadence is built into the program.
