A la carte thyroid tests from $17.56 (Total T4), with TSH at $18.36 and Free T4 at $20.76 using code TH20; two-marker TH-1 panel $39.12 (promotional pricing at time of writing).
At a glance
You can order a TSH test online without a doctor's appointment: every order includes a physician's authorization, you have blood drawn at any of 2,100+ Quest locations, and physician-reviewed results typically arrive in 24 to 48 hours. Individual thyroid tests start at $17.56 with promo code TH20, a TSH test is $18.36 and a Free T4 test is $20.76 at the promotional price, so you can start with the basics and add Free T3, reverse T3, or antibody tests only if you need them. This route suits people who want a quick, low-cost thyroid check to bring to their doctor rather than a large upfront panel.
Best suited for
- People who want a quick, low-cost TSH check without booking a doctor's appointment first
- Anyone whose insurance or clinic makes routine thyroid labs slow or expensive to obtain
- Those tracking a known thyroid result between visits, on a retest schedule set with their clinician
- Testers who prefer to build a la carte, starting with TSH and Free T4, then adding Free T3, reverse T3, or antibody tests only if needed

Key biomarker ranges
Commonly used adult reference ranges for markers this panel measures, labs vary, so always interpret results against your lab's stated ranges and with your doctor.
Commonly used reference ranges run roughly 0.4–4.0 µIU/mL; TSH moves inversely to thyroid activity, and time of day, illness, and biotin can skew results.
| Zone | Range |
|---|---|
| Low | 0–0.4 µIU/mL |
| Normal range | 0.4–4 µIU/mL |
| Mildly elevated | 4–6 µIU/mL |
| High | 6–10 µIU/mL |
Commonly used reference ranges run roughly 2.3–4.2 pg/mL; Free T3 is best interpreted alongside TSH and Free T4 rather than in isolation.
| Zone | Range |
|---|---|
| Low | 0–2.3 pg/mL |
| Normal range | 2.3–4.2 pg/mL |
| High | 4.2–6 pg/mL |
Commonly used reference ranges run roughly 0.8–1.8 ng/dL; Free T4 shows thyroid hormone supply, while TSH shows the pituitary’s demand signal.
| Zone | Range |
|---|---|
| Low | 0–0.8 ng/dL |
| Normal range | 0.8–1.8 ng/dL |
| High | 1.8–3 ng/dL |
The importance of testing
TSH is the standard first-line thyroid marker: it is the most sensitive single indicator of thyroid function and is frequently included in routine health exams. Ordering it directly means you don't need to wait for an appointment or referral to get a number, you order online, walk into a nearby Quest lab, and receive a physician-reviewed report you can take to your own clinician.
Starting small also keeps testing matched to your question. A standalone TSH (with Free T4, if you want the classic two-marker baseline) tells you whether thyroid signaling looks typical. If those results raise questions, the same promotion covers the logical next steps a la carte: Free T3 and reverse T3 for hormone conversion, Total T3 and Total T4 for overall circulating levels, and TPO/TgAb or TSI antibody tests, markers associated with autoimmune thyroid conditions such as Hashimoto's thyroiditis and Graves' disease.
Ordering directly is also a practical way to track trends between doctor visits. Because each test is inexpensive, you can recheck on the schedule you and your clinician agree on and watch whether values hold steady or drift, rather than relying on a single reading. Results live in a confidential online account, are HSA/FSA eligible, and are easy to download and share.

Order NowFrequently asked questions
Do I really not need a doctor's order to get a TSH test?
Correct, every order automatically includes a licensed physician's authorization, so no office visit, referral, or insurance is required. You purchase the test online, and the authorization is handled for you as part of checkout.
How much does a TSH test cost online?
At the current promotion, a standalone TSH test is $18.36 with code TH20 (regularly $22.95), and other individual thyroid tests range from $17.56 to $36.76 at promotional pricing. Pricing is described as limited-time, so confirm the final amount on the partner page; HSA and FSA payments are accepted for eligible tests.
Where do I go for the blood draw, and how fast are results?
You visit any of more than 2,100 Quest locations nationwide, walk-ins are welcome, or you can schedule online, and most results arrive within 24 to 48 hours. Each report is reviewed by a licensed physician and posted to your confidential online account.
Should I order just TSH, or add other thyroid tests?
TSH alone is a reasonable first check, since it is the most sensitive single indicator of thyroid function; pairing it with Free T4 (or the $39.12 TH-1 panel that combines both) gives the classic two-marker baseline. Deeper tests, Free T3, reverse T3, and TPO/TgAb or TSI antibodies, which are markers associated with autoimmune thyroid conditions, are typically follow-ups to discuss with your doctor if your initial results raise questions.
Can I order this test from any state?
Not every state, direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. In other states, testing is available wherever there is a Quest location.
