TNF-Alpha
A key inflammatory cytokine driving the systemic inflammatory response.
A more upstream and specific inflammatory signal than hs-CRP — useful when chronic inflammation is present and you want to characterise it beyond a general marker.
Optimal ranges, root causes, and the complete correction protocol — nutrition, supplements, lifestyle, hormones and peptides — plus 100+ other markers.

On its own, one marker is a data point. These panels include TNF-Alpha plus the markers that make it interpretable — each names every test, why it is on the list, and loads the whole set into your cart in one click at 10% off.
includes this + 9 more markers — Persistent aches, slow recovery, autoimmune history, high cardiovascular risk, or a raised CRP that nobody explained.
includes this + 8 more markers — Joint pain, unexplained rashes, recurring low-grade fevers, profound fatigue, or a family history of autoimmune disease.
Why your TNF-Alpha might be wrong
Most abnormal results are interference, not disease. These are the things that measurably move this specific marker — check them before you change anything. Each one says whether the number is wrong and should be repeated, badly timed and should be redrawn, or real with a cause worth explaining.
TNF-alpha is unstable and cytokine results depend heavily on how fast the sample was processed and frozen. Between-lab agreement is poor.
Do not compare results across labs. Treat a single cytokine value with real caution.
Circulating cytokines follow a daily rhythm with an overnight peak and a mid-morning trough, so two draws hours apart are not comparable.
Draw at the same time of day on every repeat.
This is an acute-phase reactant — it moves substantially during any infection, injury or inflammatory episode, and the change has nothing to do with your baseline.
Wait two weeks after any illness, vaccination or injury before drawing or interpreting.
What TNF-Alpha means in combination
A single marker tells you a little. Combinations tell you the story — these are the named patterns this marker takes part in, and what each one points at.
The combination that actually means something. The antibody alone is weak evidence; the antibody plus a clinical picture plus objective inflammation is a referral. Unexplained low white cells, platelets or haemoglobin carry more weight here than the titre does.
Rheumatology. If rheumatoid arthritis is the question, add anti-CCP — far more specific than rheumatoid factor and positive years before symptoms.
