Free T4 Test in Tucson
Free T4 — unbound thyroxine, the hormone your body can actually use
Service Description
Walk in or book online for your Free T4 Test in Tucson today. About This Test Your thyroid produces T4, but most of it travels through the blood stuck to carrier proteins where the body cannot touch it. The unbound share is the part that matters. Free T4 measures exactly that share, which is why providers pair it with TSH: one shows the request your brain is sending, the other shows what the gland delivered. What's Included Free T4 — unbound thyroxine, the portion available for your body to use. Who This Test Is For Patients following up on a TSH result that came back outside the normal range. Anyone on thyroid replacement therapy checking whether the dose is holding. People whose provider specified free T4 instead of total T4. Patients who are pregnant or on estrogen therapy, where shifting protein levels make a total T4 hard to interpret. What to Expect & Preparation Preparation: Fasting is not required. Patients on thyroid medication should be drawn ahead of that day's dose. Your Lab Visit: About 15 minutes at our second-floor lab on W St Marys Rd. Walk-ins welcome Monday through Friday, or reserve a time online. No physician order or insurance required. FSA and HSA cards accepted. Turnaround Time: Results post to your secure patient portal in 2 to 3 business days. Most people order Free T4 alongside TSH. The Essential Thyroid Test bundles TSH, Free T3, and Free T4 into a single draw. Note on Turnaround Times: Processing times are estimates and are not guaranteed. Reference laboratories may require extra time for confirmatory testing, sample re-runs, holidays, or unexpected equipment delays.
