Your concierge doctor first visit labs are not a routine checkbox — they are the clinical foundation for every decision that follows, from dosing a GLP-1 to adjusting thyroid medication or starting hormone replacement therapy.
TL;DR: At a first visit, a concierge doctor typically orders a comprehensive metabolic panel, CBC, lipid panel, HbA1c, fasting insulin, TSH with free T3/T4, a full sex hormone panel (testosterone, estradiol, progesterone, DHEA-S, SHBG), vitamin D, and ferritin. That panel — 15 to 20 individual markers — gives the clinician a complete metabolic and hormonal baseline before any prescription is written. GoodLife Health uses this same protocol for every new member in 2026, with results reviewed by a licensed clinician before treatment begins.
- Concierge first-visit panels cover 15-20 individual markers spanning metabolic, thyroid, hormonal, and micronutrient status.
- 10-12 hours of fasting is required beforehand for accurate glucose, insulin, and lipid results.
- A "normal" TSH or testosterone result can still leave a patient symptomatic — free T3/T4 and free testosterone/SHBG tell the fuller story.
- Vitamin D deficiency shows up in 35-40% of adults presenting for metabolic care.
- CBC is a required safety baseline before starting testosterone therapy or GLP-1 medications.
- Results should be reviewed by a clinician in a dedicated conversation, not delivered as an unexplained portal notification.
Why the first-visit panel matters more than an annual physical
A standard insurance-based annual physical runs a basic metabolic panel and maybe a lipid screen. A concierge doctor runs a different kind of panel — one designed to catch the metabolic dysfunction and hormonal imbalance that standard care misses for years. The difference is not just test count; it is clinical intent. The labs are ordered to answer specific questions, not to satisfy billing codes.
In 2026, the most common reason adults join a direct primary care membership is that their previous doctor told them their labs were "normal" while they gained weight, felt exhausted, and lost libido. A thorough baseline panel almost always reveals why.

What you'll need before the draw
- 10-12 hours of fasting before the blood draw. Water and plain black coffee are fine; cream, sugar, and food are not.
- A complete medication and supplement list — some supplements (biotin, high-dose vitamin D) skew specific markers.
- Any prior lab results you can share. Even a 2-year-old lipid panel helps the clinician spot a trend.
- 20-30 minutes. The draw itself takes under 10 minutes. Lab turnaround at standard reference labs is 24-72 hours.

The labs, step by step
Step 1 — Metabolic foundation (CMP + fasting insulin + HbA1c)
What it accomplishes: The comprehensive metabolic panel (CMP) reads kidney function (creatinine, BUN), liver enzymes (ALT, AST), electrolytes, and fasting glucose in a single draw. Adding HbA1c gives a 90-day glucose average, and fasting insulin reveals insulin resistance years before glucose goes abnormal.
Why it matters: A patient can have a fasting glucose of 94 mg/dL — technically normal — with a fasting insulin of 22 µIU/mL, indicating significant insulin resistance. That finding alone changes the conversation about whether a GLP-1 is indicated and which one to consider.
A patient can have a fasting glucose of 94 mg/dL — technically normal — with a fasting insulin of 22 µIU/mL, indicating significant insulin resistance. Glucose normalizes last; insulin dysregulation is the earlier signal, which is why skipping fasting insulin because the glucose looks fine is a common mistake.
Specific markers: Glucose, BUN, creatinine, eGFR, sodium, potassium, CO2, calcium, total protein, albumin, bilirubin, ALT, AST, alkaline phosphatase, HbA1c, fasting insulin.
Expected outcome: A fasting insulin above 10 µIU/mL in a fasting state is worth discussing. HbA1c above 5.7% signals pre-diabetes and makes the case for metabolic intervention.
Common mistake: Skipping the fasting insulin because the glucose looks fine. Glucose normalizes last — insulin dysregulation is the earlier signal.
---
Step 2 — Lipid panel (standard + advanced when indicated)
What it accomplishes: Total cholesterol, LDL, HDL, triglycerides, and the triglyceride-to-HDL ratio. A ratio above 3.0 is a practical proxy for insulin resistance and small-dense LDL particle dominance.
Why it matters: Triglycerides above 150 mg/dL combined with HDL below 40 mg/dL (men) or 50 mg/dL (women) in a fasting state is a metabolic syndrome marker. This panel shapes the diet and medication conversation immediately.
Common mistake: Reading only LDL in isolation. A patient with an LDL of 110 mg/dL and a triglyceride-to-HDL ratio of 4.5 carries more cardiovascular risk than the LDL alone suggests.
---
Step 3 — Thyroid panel (TSH + free T3 + free T4)
What it accomplishes: TSH alone is what most primary care offices run. A concierge doctor adds free T3 and free T4 to distinguish between a pituitary signal problem and a conversion problem. Some patients convert T4 to T3 poorly, a pattern TSH alone misses entirely.
Why it matters: Subclinical hypothyroidism — TSH between 2.5 and 4.5 mIU/L with symptoms — is one of the most under-treated causes of weight resistance, fatigue, and cognitive slowing in adults over 35.
Specific markers: TSH, free T3, free T4. Thyroid antibodies (TPO-Ab, TgAb) are added when autoimmune thyroid disease is suspected.
Common mistake: Treating a TSH of 3.8 as "normal" when the patient reports cold intolerance, constipation, and 20 lbs of unexplained weight gain. The reference range is population-based, not symptom-adjusted.
The thyroid and hormone imbalance guide covers the T3/T4 conversion issue in more detail.

Step 4 — Sex hormone panel
What it accomplishes: This is where a concierge first-visit panel diverges most sharply from standard care. The full sex hormone panel covers total testosterone, free testosterone, estradiol (E2), progesterone (day 21 of cycle for premenopausal women), DHEA-S, SHBG, and LH/FSH.
Why it matters for women: Low testosterone in women causes low libido, muscle loss, and mood instability — but it is almost never tested at a standard annual visit. SHBG determines how much testosterone is actually bioavailable; a woman with a "normal" total testosterone of 38 ng/dL but SHBG of 110 nmol/L has very little free testosterone in circulation.
Why it matters for men: Total testosterone reference ranges are broad (300–1000 ng/dL). A man at 310 ng/dL is technically in range but functionally low. Free testosterone and SHBG tell the complete story.
Common mistake: Drawing testosterone in the afternoon. Total testosterone follows a diurnal rhythm, peaking between 7–10 AM. An afternoon draw can read 15–20% lower than a morning draw for the same patient.
---
Step 5 — Micronutrients (vitamin D, ferritin, B12)
What it accomplishes: Vitamin D (25-OH), ferritin, and B12 are the three micronutrient markers most consistently correlated with fatigue, mood, and immune function in adults seeking care for metabolic or hormonal concerns.
Why it matters: Ferritin below 30 ng/mL produces fatigue and hair loss indistinguishable from thyroid or hormonal symptoms. Treating a ferritin of 12 ng/mL with hormone therapy will not resolve the fatigue. Vitamin D below 30 ng/mL impairs testosterone production, immune regulation, and insulin sensitivity.
Expected outcome: In 2026, population data from multiple outpatient labs consistently shows vitamin D deficiency in 35–40% of adults presenting for metabolic care. Supplementation protocols typically target a serum level of 50–70 ng/mL.
Common mistake: Running serum B12 and stopping there. Active B12 deficiency can exist with a serum B12 in the "normal" range (200–900 pg/mL). Methylmalonic acid is the confirmatory test when B12 deficiency is clinically suspected.
---
Step 6 — CBC with differential
What it accomplishes: Complete blood count reads red cell indices (hemoglobin, hematocrit, MCV), white cell differential, and platelet count. It establishes anemia type, screens for infection, and is a baseline requirement before starting testosterone therapy in men (hematocrit monitoring) or GLP-1 therapy.
Why it matters: Testosterone therapy raises hematocrit. A baseline above 50% before starting therapy is a clinical reason to delay or adjust dosing. You cannot know that without running the CBC.
Testosterone therapy raises hematocrit. A baseline above 50% before starting therapy is a clinical reason to delay or adjust dosing — the CBC is not optional, it informs safety monitoring for every common treatment in this space.
Common mistake: Skipping the CBC when the patient presents for "hormones only." The CBC is not optional — it informs safety monitoring for every common treatment in this space.

Step 7 — Inflammatory and metabolic extras (when indicated)
Depending on intake history, a clinician may add:
- hsCRP — high-sensitivity C-reactive protein, a marker of systemic inflammation predictive of cardiovascular risk
- Uric acid — elevated in metabolic syndrome and relevant when starting a GLP-1
- PSA — prostate-specific antigen for men over 40 before starting testosterone
- Cortisol (AM) — when symptoms suggest adrenal dysfunction or the patient is on chronic corticosteroids
- Homocysteine — when cardiovascular risk is elevated or B-vitamin deficiency is suspected
Not every panel includes all of these. A good clinician adds them based on your history, not as a default upsell.

Troubleshooting: what to do when results come back
Common results and what to do about them
based on the troubleshooting scenarios below
| Result you got back | What to do |
|---|---|
| TSH is 3.2 mIU/L and you have symptoms | Do not accept "that's normal" as a final answer — request free T3 and free T4 if they were not run. |
| Testosterone is "in range" but you feel low | Ask for SHBG and free testosterone; total testosterone alone leaves out bioavailable hormone. |
| Vitamin D came back at 22 ng/mL | Most clinicians target 50-70 ng/mL and may prescribe 5,000 IU/day, with a recheck at 90 days. |
| Ferritin is below 30 ng/mL | Oral iron takes 3-4 months to meaningfully raise ferritin; IV iron is faster when symptoms are severe. |
| Results show pre-diabetes (HbA1c 5.7-6.4%) | This is the inflection point where lifestyle intervention combined with GLP-1 therapy has the highest long-term impact. |
| You were told to fast but didn't | Reschedule the draw — a non-fasted lipid panel is inaccurate. |
Your TSH is 3.2 mIU/L and you have symptoms. Do not accept "that's normal" as a final answer. Request free T3 and free T4 if they were not run. Symptom context matters; the population reference range does not account for individual variation.
Your testosterone is "in range" but you feel low. Ask for SHBG and free testosterone. Total testosterone at 340 ng/dL with SHBG at 80 nmol/L leaves very little bioavailable hormone.
Your vitamin D came back at 22 ng/mL. Standard supplementation at 2,000 IU/day will raise levels slowly — most clinicians target 50–70 ng/mL and may prescribe 5,000 IU/day to get there faster, with a recheck at 90 days.
Your ferritin is below 30 ng/mL. Iron deficiency without anemia is real and under-treated. Oral iron supplementation takes 3–4 months to meaningfully raise ferritin. IV iron (Ferinject or Injectafer) is faster when symptoms are severe.
Results show pre-diabetes (HbA1c 5.7–6.4%). This is the clinical inflection point where lifestyle intervention combined with GLP-1 therapy has the highest long-term impact. The SURMOUNT-1 trial data (2022, n=2,539) showed tirzepatide reduced HbA1c by 2.1 percentage points in non-diabetic adults with obesity at 72 weeks.
You were told to fast but didn't. Reschedule the draw. A non-fasted lipid panel is inaccurate. Triglycerides in particular spike post-meal and will produce a misleading result.
