JustLabs all-in: $28 test + $18 order fee
No insurance, no doctor visit, and no separate bill from the lab afterward.
What You Pay
| Reverse T3 test | $28 |
| Lab & Physician Order FeeQuest Diagnostics blood draw and independent physician order, once per order | $18 |
| Total | $46 |
The $18 fee is charged once per order, not per test. Add other tests to the same order and you pay only their test prices on top, with everything drawn in the same visit.
Why Reverse T3 Test Prices Vary
Online lab services charge for the physician order and the blood draw differently: some build them into each test price, others add a per-order fee. Compare the total for your order, not the test price alone.
- JustLabs: one $18 fee per order covering the Quest Diagnostics blood draw and the independent physician order, however many tests you add.
- Labcorp OnDemand: no separate fee; the physician service is built into each test price.
- Quest Health: $6 per order (physician service fee) on top of the test price.
- Walk-In Lab: $6 per order (physician fee) on top of the test price.
- Ulta Lab Tests: $12.95 per order (specimen collection fee) on top of the test price.
- TestWell: $6 per order (lab processing fee) on top of the test price.
Because the JustLabs fee is once per order, each test you add to the same order adds only its own price. See every price side by side on the lab test price comparison.
