TIBC test cost — $12–$23.95
TIBC · measured in µg/dL
Iron-binding capacity — completes the saturation math.
Optimal windowReference range
An assay-specific reference interval has not yet been added to this guide.
Use the interval printed beside this exact result, including its specimen, units, age/sex group and collection conditions. A range for a similarly named test may not apply.
Optimal range / clinical target
PeptideLab has not verified a separate ‘optimal’ target for this measurement. Reference intervals, diagnostic cutoffs and treatment targets answer different questions.
Tests that include TIBC
TIBC is included in Iron panel (Fe/TIBC/Ferritin). GoodLabs and Ulta prices below cover that panel, not an individual biomarker. Test prices are shown before separate collection fees.
Tracking more than one biomarker?
Build a list to compare test and panel combinations, with one blood-draw fee in your GoodLabs estimate.
$12 blood draw per visit, added once to your order.
Collection fee is additional; not included in this test price.
Does insurance cover TIBC testing?
When a clinician orders TIBC for a diagnosis or to follow a known condition, most plans cover it — and many cover routine screening as $0 preventive care for eligible adults. The catch is you need a qualifying reason and an in-network order; a “I just want to see my number” request often isn’t covered, and if you haven’t met your deductible you can end up paying the lab’s full list price anyway.
The direct-pay prices above skip insurance entirely: you pay the cash price, test on your own schedule with no doctor visit, and it’s HSA/FSA-eligible. For a single marker that’s often cheaper — and faster — than a copay plus deductible exposure.
TIBC inside a bundle
Every compared membership/panel that includes TIBC, cheapest first. Worth it when you want several markers at once rather than a single test.

What TIBC is
Total iron-binding capacity — a measure of the blood's total capacity to bind iron, reflecting transferrin availability. It rises in iron deficiency and falls in overload or inflammation.
Why it matters for longevity & performance
Used with serum iron to compute transferrin saturation; high TIBC with low iron confirms deficiency.
TIBC testing — frequently asked
Do I need to fast for a TIBC test?
No. TIBC does not require fasting — you can test any time of day.
Do I need a doctor's order to get a TIBC test?
No. Direct-to-consumer labs (GoodLabs, Ulta, Quest and Labcorp OnDemand) include the physician order in the price — you order online and visit a draw site, no appointment with your own doctor needed.
How fast are TIBC results?
Usually 1–3 business days after your blood draw; most results post to the lab's online portal.
What's the difference between the standard and optimal TIBC range?
Reference intervals describe results in a reference population; they do not by themselves diagnose or exclude disease. A treatment target depends on the condition and the person. PeptideLab has not verified a separate ‘optimal’ target for this measurement. Reference intervals, diagnostic cutoffs and treatment targets answer different questions.
Does insurance cover TIBC testing?
Often, when ordered for a diagnosis; many plans cover it as preventive care at no cost for eligible adults. The direct-pay prices above let you skip insurance and test on your own schedule.
