## Is it the same test?

Yes — analyzed at the same CLIA-certified lab (CPT 84146); assay, reference range and result are identical.

## When is JustLabs the better choice?

- Multi-test orders: from two tests up, JustLabs usually totals less because its $28 in fees is paid once — their 4-test Basic Wellness Panel is $30 + $28 = $58 versus TestWell's General Wellness Panel at $95.99 all-in ($60.99 in NY/NJ, where JustLabs doesn't operate)
- Eight single tests are cheaper at JustLabs even after fees, mostly specialty assays where their sticker is far below ours: heavy metals panel, Omega-3 Index, LH, prolactin, thyroid antibodies, PSA free & total, and by about a dollar CoQ10 and folate
- Faster quoted turnaround (1-2 business days) on many routine tests
- You're ordering two or more tests in one Quest draw and want the lowest total — JustLabs' $28 in fees is paid once, so bigger orders favor them.
- You want Spanish-language test pages; TestWell's Spanish mirror is still rolling out.


## Price questions

### Is the Prolactin test at TestWell the same as JustLabs's?

Yes — the sample is analyzed at the same CLIA-certified lab (CPT 84146), so the assay, reference range and result are identical. What differs is the price, the ordering experience and what else is bundled.

### Are JustLabs's prices all-in?

No. JustLabs adds $18.00 lab draw fee and $10.00 physician order fee per order on top of the $12.00 sticker, so one Prolactin test comes to $40.00. Ordering several tests at once spreads that fee out. TestWell charges one $6.00 lab fee per order, shown before checkout.

### How current are these prices?

TestWell's price is read from the live catalog every time this page loads and is exactly what checkout charges. JustLabs's sticker and fees were read from its public ordering pages on 2026-09-18 and are re-verified at least monthly; the same rows power our Blood Test Price Index.

### Do I need a doctor's order for a Prolactin test?

Not at TestWell — a licensed physician in our network reviews and authorizes every order, and the requisition is emailed to you (usually within the hour). JustLabs also includes physician authorization in its price.
