Lymphocytes test cost — $3.20–$21.95
Lymphocytes · measured in K/µL
Adaptive-immunity cells — low counts mark immune aging.
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 Lymphocytes
Lymphocytes is included in CBC w/ differential. 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 Lymphocytes testing?
When a clinician orders Lymphocytes 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.
Lymphocytes inside a bundle
Every compared membership/panel that includes Lymphocytes, cheapest first. Worth it when you want several markers at once rather than a single test.

What Lymphocytes is
T, B, and NK cells driving adaptive immunity. Low counts reflect stress, steroids, infection, or immune aging; high can be reactive or clonal.
Why it matters for longevity & performance
Higher-normal lymphocytes (a favorable NLR) indicate preserved immune competence; lymphopenia predicts higher mortality and immunosenescence.
Lymphocytes & peptides — what to watch
If you’re running peptides, TRT or HRT, these are the compounds studied in relation to Lymphocytes — useful for deciding what to track. Research associations for monitoring, not medical or dosing advice. Tap one for its full profile.
Lymphocytes testing — frequently asked
Do I need to fast for a Lymphocytes test?
No. Lymphocytes does not require fasting — you can test any time of day.
Do I need a doctor's order to get a Lymphocytes 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 Lymphocytes 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 Lymphocytes 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 Lymphocytes?
Compounds studied in relation to Lymphocytes include Thymosin Alpha-1, Thymalin. These are research associations for monitoring — not medical or dosing advice.
Does insurance cover Lymphocytes 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.
