Order the CBC w/ Diff test — $21.99 Full TestWell vs Request A Test comparison

Is it the same test?

Yes. Both orders are analyzed at the same CLIA-certified lab under the same CPT code (85025), so the assay, the reference range and the number on your report are identical. You are paying for the ordering experience, the physician authorization and any bundling — not a different test.

Where does the price difference come from?

Request A Test lists a lower-looking sticker and adds a $4.00 service fee at checkout, so a single test costs $33.00. TestWell's $21.99 sticker plus one $6.00 lab processing fee — $27.99 — is the whole price. The fee gap narrows when several tests share one order at either company.

When is Request A Test the better choice?

Larger catalog: it says its menu holds over 1,000 tests, and it lists about 200 packages
In business since 2002, with a new promotion each month
Results as early as one business day on routine tests, by its own estimate
You want a clinician consult included. A licensed physician authorizes every TestWell order, but that review is not a visit — there is no call to walk through results unless you bring them to your own provider.
You can't get to a draw site. TestWell is venous-draw only at Quest, Labcorp and BioReference locations; we don't ship at-home finger-prick kits.

Frequently asked questions

Is the CBC w/ Diff test at TestWell the same as Request A Test's?

Yes — the sample is analyzed at the same CLIA-certified lab (CPT 85025), so the assay, reference range and result are identical. What differs is the price, the ordering experience and what else is bundled.

Are Request A Test's prices all-in?

No. Request A Test adds $4.00 service fee per order on top of the $29.00 sticker, so one CBC w/ Diff test comes to $33.00. 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 what checkout charges for a Labcorp draw ($23.99 all-in at Quest).

Do I need a doctor's order for a CBC w/ Diff 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). Request A Test also includes physician authorization in its price.
