Inflammation
ESR test cost — $4.80–$15
ESR · measured in mm/hr
A nonspecific inflammation gauge — keep it low.
Lower is betterReference 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.

Does insurance cover ESR testing?
When a clinician orders ESR 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.
What ESR is
The rate at which red cells settle in a tube over one hour — an indirect, nonspecific index of inflammation driven by fibrinogen and other acute-phase proteins. Slower and less specific than CRP.
Why it matters for longevity & performance
Elevated ESR reflects chronic inflammatory burden linked to cardiovascular disease, cancer, and mortality; many longevity panels prefer hs-CRP as the sharper marker.
ESR & peptides — what to watch
If you’re running peptides, TRT or HRT, these are the compounds studied in relation to ESR — useful for deciding what to track. Research associations for monitoring, not medical or dosing advice. Tap one for its full profile.
ESR testing — frequently asked
Do I need to fast for a ESR test?
No. ESR does not require fasting — you can test any time of day.
Do I need a doctor's order to get a ESR 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 ESR 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 ESR 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.
Which peptides affect ESR?
Compounds studied in relation to ESR include BPC-157, Thymosin Alpha-1. These are research associations for monitoring — not medical or dosing advice.
Does insurance cover ESR 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.
